Continental Airlines, Inc.

We are the world’s sixth largest airline (as measured by the number of scheduled miles flown by revenue passengers, known as revenue passenger miles, in 2004). Together with ExpressJet Airlines, Inc. (operating as Continental Express), a wholly owned subsidiary of ExpressJet Holdings, Inc. from which we purchase seat capacity, and our wholly owned subsidiary, Continental Micronesia, Inc., each a Delaware corporation, we operate more than 2,500 daily departures throughout the Americas, Europe and Asia. As of September 30, 2005, we flew to 128 domestic and 119 international destinations and offered additional connecting service through alliances with domestic and foreign carriers. We directly served 23 European cities, eight South American cities, Tel Aviv, Hong Kong, Beijing and Tokyo as of September 30, 2005. In addition, we provide service to more destinations in Mexico and Central America than any other U.S. airline, serving 40 cities. Through our Guam hub, Continental Micronesia provides extensive service in the western Pacific, including service to more Japanese cities than any other United States carrier.

We are a Delaware corporation, with executive offices located at 1600 Smith Street, Houston, Texas 77002. Our telephone number is (713) 324-2950.

Risk factors

You should carefully consider the risks and uncertainties described below, together with all of the other information in this prospectus supplement and the accompanying prospectus, before purchasing our common stock. If any of these risks actually occurs, our business, financial condition or results of operations could be materially adversely affected. As a result, the price of our common stock could decline, and you could lose part or all of your investment.

Primarily due to record-high fuel prices and the continued weak domestic fare environment, the current U.S. domestic network carrier financial environment continues to be poor and could deteriorate further. Among the many factors that threaten us are the continued rapid growth of low-cost carriers and resulting downward pressure on domestic fares, high fuel costs, high labor costs for our flight attendants, excessive taxation, increased security costs and significant pension liabilities. These factors are discussed below as well as in the “Overview” section of Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2004 Form 10-K/ A.

RISK FACTORS RELATING TO THE COMPANY

We continue to experience significant losses

We have had substantial losses since September 11, 2001, the magnitude of which is not sustainable. Although revenue trends have been improving, we expect to incur a significant loss in the fourth quarter and full year 2005 due in large part to record high fuel prices. We have been able to implement some fare increases on certain domestic and international routes in recent months, but these increases have not fully offset the substantial increase in fuel prices.

We believe that under current conditions, absent adverse factors outside of our control, such as additional terrorist attacks, hostilities involving the United States, a further delay in the restart of the Gulf Coast refineries damaged by the recent hurricanes or further significant increases in crude oil prices, our existing liquidity and projected 2006 cash flows will be sufficient to fund current operations and other financial obligations through 2006. However, we have significant financial obligations due in 2007 and thereafter, and it is possible that we will have inadequate liquidity to meet those obligations if the current adverse domestic fare environment for network carriers does not improve materially, fuel prices remain high and we are unable to increase revenue or decrease costs considerably or raise additional liquidity through financing activities and/or by selling non-strategic assets. Our recent pay and benefit cost reductions are helping us reduce our overall costs, but we do not expect that these reductions in and of themselves will provide sufficient liquidity or restore our long-term profitability in the current environment.

Record high fuel prices are materially and adversely affecting our operating results

Fuel costs, which are currently at unprecedented high levels, constitute a significant portion of our operating expense. Fuel costs represented approximately 15.7% of our operating expenses for the year ended December 31, 2004 and approximately 20.8% of our operating expenses for the nine months ended September 30, 2005. Fuel expense is currently our single largest operating expense item.

In addition, fuel prices and supplies are influenced significantly by international political and economic circumstances, such as the political crises in Venezuela and Nigeria in late 2002 and early 2003 and post-war unrest in Iraq, as well as OPEC production curtailments, a disruption of oil imports, other conflicts in the Middle East, environmental concerns, weather and other unpredictable events. Further, Hurricane Katrina and Hurricane Rita caused widespread disruption to oil production, refinery operations and pipeline capacity in portions of the U.S. Gulf Coast. As a result of these disruptions, the price of jet fuel increased significantly and the availability of jet fuel supplies was diminished.

S-3

Risk factors

Further increases in jet fuel prices or disruptions in fuel supplies, whether as a result of natural disasters or otherwise, could have a material adverse effect on our results of operations, financial position or liquidity.

From time to time we enter into petroleum swap contracts, petroleum call option contracts and/or jet fuel purchase commitments to provide some short-term hedge protection (generally three to six months) against sudden and significant increases in jet fuel prices, while simultaneously ensuring that we are not competitively disadvantaged in the event of a substantial decrease in the price of jet fuel. However, as of September 30, 2005, we did not have any fuel hedges in place.

We are also at risk for ExpressJet’s fuel costs. Under our capacity purchase agreement and a related fuel purchase agreement with ExpressJet, we pay all of ExpressJet’s fuel expense plus a margin on their fuel expense up to a cap provided in the capacity purchase agreement and related fuel purchase agreement (which margin applies only to the first 71.2 cents per gallon, including fuel taxes). The portion of our capacity purchase expense comprising ExpressJet’s fuel, fuel taxes and margin was approximately $387 million for the nine months ended September 30, 2005, as compared to approximately $238 million for the same period in 2004. This significant increase was primarily due to escalating fuel prices and an increased number of ExpressJet flights period over period.

An increase in early retirements could negatively impact our operations and could result in a material adverse effect on our liquidity

We could experience an increase in early retirements caused by concern among our employees about our financial stability. The potential of an increase in early retirements could be exacerbated by the fact that our employees are entitled to lump-sum distributions from our defined benefit pension plans upon their retirement, including early retirement within the provisions of the plans. Some of our competitors have terminated, or have sought to terminate, their defined benefit pension plans in bankruptcy, which can cause employees to receive less than the full amount of their pension benefits under applicable federal pension benefit insurance, and can also limit or eliminate the ability of employees to receive their pension benefits in a lump-sum. If liquidity concerns increase, we could experience a significant increase in early retirements which could negatively impact our operations and materially increase our near-term funding obligations to our defined benefit pension plans, which could itself result in a material adverse effect on our liquidity.

Our high leverage may affect our ability to satisfy our significant financing needs or meet our obligations

We have a high proportion of debt compared to our equity capital.

As of September 30, 2005, we had approximately:

Our combined long-term debt and capital lease obligations coming due in the fourth quarter of 2005 total approximately $356 million. We also have significant operating leases and facility rental costs. Annual aircraft and facility rental expense under operating leases approximated $1.3 billion for the year ended December 31, 2004 and $1.0 billion for the nine months ended September 30, 2005.

In addition, we have substantial commitments for capital expenditures, including for the acquisition of new aircraft and related spare engines. As of September 30, 2005, we had firm purchase commitments

S-4

Risk factors

for new aircraft and related spare engines with an estimated aggregate cost of approximately $2.7 billion. In addition, we have lease commitments for five used 757-300 aircraft not yet delivered and options to purchase an additional 30 Boeing aircraft. We are scheduled to take delivery of six Boeing aircraft over the remaining three months of 2005 (three new 737-800s and three used 757-300s) and eight in 2006 (six new 737-800s and two used 757-300s), with delivery of the remaining 46 Boeing aircraft occurring from 2007 through 2011.

In May 2005, we obtained a lease financing commitment from a third party for the seven new Boeing 737-800 aircraft scheduled to be delivered in 2005. We also have backstop lease financing for the six 737-800 aircraft expected to be delivered in 2006 and the two 777-200ER aircraft expected to be delivered in 2007. By virtue of these agreements, we have secured financing for all Boeing aircraft scheduled to be delivered through 2007. However, we currently do not have backstop financing or any other financing in place for the remainder of the Boeing firm aircraft that are scheduled to be delivered between 2008 and 2011. Further financing will be needed to satisfy our capital commitments for our firm aircraft. We can provide no assurance that sufficient financing will be available for the aircraft on order or other related capital expenditures, or for our capital expenditures generally.

We also have substantial pension obligations. Based on current legislation and assumptions, we will be required to contribute in excess of $1.5 billion to our defined benefit pension plans over the five year period from 2005 through 2009. Year-to-date, we have contributed $304 million in cash to our defined benefit pension plans, meeting our minimum pension contribution requirements for 2005.

Additional financing will be needed to satisfy our capital commitments. We cannot predict whether sufficient financing will be available. As of September 30, 2005, our senior unsecured debt was rated Caa2 by Moody’s and CCC+ by Standard & Poor’s. Reductions in our credit ratings may increase the cost and reduce the availability of financing to us in the future. We do not have any debt obligations that would be accelerated as a result of a credit rating downgrade. However, we would have to post additional collateral of approximately $60 million under our bank-issued credit card processing agreement if our debt rating falls below Caa3 as rated by Moody’s or CCC- as rated by Standard & Poor’s. We would also be required to post additional collateral of up to $27 million under our workers’ compensation program if our debt rating falls below Caa2 as rated by Moody’s or CCC+ as rated by Standard & Poor’s.

Our bank-issued credit card processing agreement also contains certain financial covenants which require, among other things, us to maintain a minimum EBITDAR (generally, earnings before interest, taxes, depreciation, amortization and rentals, adjusted for certain special charges) to fixed charges (generally, interest and total rentals) ratio of 0.9 to 1.0 through June 2006 and 1.1 to 1.0 thereafter. The liquidity covenant in the agreement requires us to maintain a minimum level of $1.0 billion of unrestricted cash and short-term investments. Although we are currently in compliance with these covenants, failure to maintain such compliance would result in our being required to post up to an additional $360 million of cash collateral, which would adversely affect our liquidity. Depending on our unrestricted cash and short-term investments balance at the time, the posting of a significant amount of cash collateral could cause our unrestricted cash and short-term investments balance to fall below the $1.0 billion minimum balance requirement under our $350 million secured loan facility, resulting in a default under such facility.

Our labor costs or labor disruptions could threaten future liquidity

Labor costs constitute a significant percentage of our total operating costs. Labor costs (including employee incentives) constituted 27.8% of our total operating expenses for the year ended December 31, 2004 and 24.2% for the nine months ended September 30, 2005.

S-5

Risk factors

Even given the effect of pay and benefit cost reductions implemented beginning in April 2005, we estimate that our wages, salaries and benefits cost per available seat mile, measured on a stage length adjusted basis, will continue to be higher than that of many of our competitors. We are currently in negotiations with the union representing our flight attendants, with the assistance of an appointed federal mediator, in an effort to reach an agreement for pay and benefit reductions and work rule changes. There is no assurance that an agreement will be reached or, if reached, will be ratified by the flight attendants. Although we enjoy generally good relations with our employees, we can provide no assurance that we will not experience labor disruptions in the future. Any disruptions which result in a prolonged significant reduction in flights would have a material adverse impact on our results of operations and financial condition.

Our net operating loss carryforwards may be limited

At December 31, 2004, we had estimated net operating loss carryforwards, or NOLs, of $3.2 billion for federal income tax purposes that will expire beginning in 2006 through 2024. If we were to have a change of ownership under current conditions, our annual NOL utilization could be limited to approximately $27 million per year, before consideration of any built-in gains.

For financial reporting purposes, income tax benefits recorded on net losses result in deferred tax assets. We are required to provide a valuation allowance for deferred tax assets to the extent management determines that it is more likely than not that such deferred tax assets will ultimately not be realized. Due to our continued losses, we were required to provide a valuation allowance on deferred tax assets recorded on losses during the first quarter of 2004. As a result, part of our first and all of our second, third and fourth quarter 2004 and all of our 2005 net losses were not reduced by any tax benefit. Furthermore, we expect to be required to provide additional valuation allowances in conjunction with deferred tax assets recorded on losses in the future.

RISK FACTORS RELATING TO THE AIRLINE INDUSTRY

Additional terrorist attacks or international hostilities may further adversely affect our financial condition, results of operations and prospects

As described in greater detail in our filings with the SEC, the terrorist attacks of September 11, 2001 involving commercial aircraft severely and adversely affected our financial condition, results of operations and prospects, and the airline industry generally. Additional terrorist attacks, even if not made directly on the airline industry, or the fear of such attacks (including elevated national threat warnings or selective cancellation or redirection of flights due to terror threats), could negatively affect us and the airline industry. Those potential negative effects include increased security, insurance and other costs for us, higher ticket refunds and decreased ticket sales. The war in Iraq decreased demand for air travel during the first half of 2003, especially in transatlantic markets, and additional international hostilities could potentially have a material adverse impact on our financial condition, liquidity and results of operations. Our financial resources might not be sufficient to absorb the adverse effects of any further terrorist attacks or an increase in post-war unrest in Iraq or other international hostilities involving the United States.

The airline industry is highly competitive and susceptible to price discounting

The U.S. airline industry is increasingly characterized by substantial price competition, especially in domestic markets. Carriers use discount fares to stimulate traffic during periods of slack demand, to generate cash flow and to increase market share. Some of our competitors have substantially greater financial resources or lower cost structures than we have, or both. In recent years, the market share held by low cost carriers has increased significantly and is expected to continue to increase, which is

S-6

Risk factors

dramatically changing the airline industry. For the last three years, large network carriers have generally lost a significant amount of pricing power in domestic markets, which has contributed to the dramatic losses for us and the airline industry generally. We cannot predict if or for how long these trends will continue.

US Airways Group, Inc., United Air Lines, Inc. and, most recently, Delta Air Lines, Inc. and Northwest Airlines, Inc., as well as several small competitors, have filed for bankruptcy protection. Other carriers could file for bankruptcy or threaten to do so to reduce their costs. Carriers operating under bankruptcy protection can operate in a manner that would be adverse to us and could emerge from bankruptcy as more vigorous competitors with substantially lower costs than ours.

Since its deregulation in 1978, the U.S. airline industry has undergone substantial consolidation, and we may in the future experience additional consolidation. We routinely monitor changes in the competitive landscape and engage in analysis and discussions regarding our strategic position, including alliances, asset acquisitions and business combination transactions. We have had, and expect to continue to have, discussions with third parties regarding strategic alternatives. The impact of any consolidation within the U.S. airline industry cannot be predicted at this time.

Additional security requirements may increase our costs and decrease traffic

Since September 11, 2001, the Department of Homeland Security, or DHS, and Transportation Security Administration have implemented numerous security measures that affect airline operations and costs, and are likely to implement additional measures in the future. Most recently, DHS has begun to implement the US-VISIT (a program of fingerprinting and photographing foreign visa holders), announced that it will implement greater use of passenger data for evaluating security measures to be taken with respect to individual passengers, expanded the use of federal air marshals on our flights (thus displacing additional revenue passengers), begun investigating a requirement to install aircraft security systems (such as active devices on commercial aircraft as countermeasures against portable surface to air missiles) and expanded cargo and baggage screening. DHS has also required certain flights to be cancelled on short notice for security reasons, and has required certain airports to remain at higher security levels than other locations.

In addition, foreign governments have also begun to institute additional security measures at foreign airports that we serve, out of their own security concerns or in response to security measures imposed by the U.S.

A large part of the costs of these security measures is borne by the airlines and their passengers, and we believe that these and other security measures have the effect of decreasing the attractiveness of air transportation as compared to other modes of transportation in general and thus decreasing traffic. Security measures imposed by the U.S. and foreign governments after September 11, 2001 have increased our costs and adversely affected us and our financial results, and additional such measures taken in the future may result in similar adverse effects.

Extensive government regulation could increase our operating costs and restrict our ability to conduct our business

As evidenced by the security measures discussed above, airlines are subject to extensive regulatory and legal compliance requirements that result in significant costs. Additional laws, regulations, taxes and airport rates and charges have been proposed from time to time that could significantly increase the cost of airline operations or reduce revenue. The Federal Aviation Administration, or FAA, from time to time issues directives and other regulations relating to the maintenance and operation of aircraft that require significant expenditures. Some FAA requirements cover, among other things, retirement of older aircraft, security measures, collision avoidance systems, airborne windshear avoidance systems,

S-7

Risk factors

noise abatement and other environmental concerns, commuter aircraft safety and increased inspections and maintenance procedures to be conducted on older aircraft. We expect to continue incurring expenses to comply with the FAA’s regulations.

Many aspects of airlines’ operations are also subject to increasingly stringent federal, state and local laws protecting the environment. Future regulatory developments in the U.S. and abroad could adversely affect operations and increase operating costs in the airline industry. For example, potential future actions that may be taken by the U.S. government, foreign governments, or the International Civil Aviation Organization to limit the emission of greenhouse gases by the aviation sector are unknown at this time, but the impact to us and our industry is likely to be adverse and could be significant.

Additionally, because of significantly higher security and other costs incurred by airports since September 11, 2001, many airports have significantly increased their rates and charges to air carriers, including to us, and may do so again in the future. Restrictions on the ownership and transfer of airline routes and takeoff and landing slots have also been proposed. The ability of U.S. carriers to operate international routes is subject to change because the applicable arrangements between the United States and foreign governments may be amended from time to time, or because appropriate slots or facilities are not made available. We cannot provide assurance that current laws and regulations, or laws or regulations enacted in the future, will not adversely affect us.

Our results of operations fluctuate due to seasonality and other factors associated with the airline industry

Due to greater demand for air travel during the summer months, revenue in the airline industry in the second and third quarters of the year is generally stronger than revenue in the first and fourth quarters of the year for most U.S. air carriers. Our results of operations generally reflect this seasonality, but have also been impacted by numerous other factors that are not necessarily seasonal, including excise and similar taxes, weather, air traffic control delays and general economic conditions, as well as the other factors discussed above. As a result, our operating results for a quarterly period are not necessarily indicative of operating results for an entire year, and historical operating results are not necessarily indicative of future operating results.

S-8

Use of proceeds

We expect to receive approximately $202.4 million of net proceeds after deducting estimated offering expenses from this offering ($232.7 million if the underwriter’s overallotment option is exercised in full). We intend to use these net proceeds for general corporate purposes.

S-9

Underwriting

We are offering the shares of our Class B common stock described in this prospectus supplement and the related prospectus through UBS Securities LLC. We have entered into an underwriting agreement with UBS Securities LLC. Subject to the terms and conditions of the underwriting agreement, UBS Securities LLC has agreed to purchase 18,000,000 shares of our Class B common stock.

The underwriting agreement provides that the underwriter must buy all of the shares if it buys any of them.

Our Class B common stock is offered subject to a number of conditions, including:

We have been advised that the underwriter intends to make a market in our Class B common stock. However, it is not obligated to do so and may discontinue making a market at any time without notice.

In connection with this offering, the underwriter or securities dealers may distribute prospectus supplements and the related prospectuses electronically.

We have agreed to indemnify the underwriter against certain liabilities, including certain liabilities under the Securities Act of 1933, as amended. If we are unable to provide this indemnification, we have agreed to contribute to payments the underwriter may be required to make in respect of those liabilities.

Over-allotment option

We have granted the underwriter an option to buy up to an aggregate of 2,700,000 additional shares of our common stock. The underwriter may exercise this option solely for the purpose of covering over-allotments, if any, made in connection with this offering. The underwriter has 30 days from the date of this prospectus supplement to exercise this option.

Commissions and discounts

Shares sold by the underwriter to the public are being offered at the offering price set forth on the cover of this prospectus supplement. Any shares sold by the underwriter to securities dealers may be sold at a discount of up to $0.03 per share from the public offering price. Sales of shares made outside of the United States may be made by affiliates of the underwriter.

If all the shares are not sold at the public offering price, the underwriter may change the public offering price and the other selling terms. Upon execution of the underwriting agreement, the underwriter will be obligated to purchase the shares at the prices and upon the terms stated therein and, as a result, will thereafter bear any risk associated with changing the offering price to the public or other selling terms. The underwriter has informed us that it does not expect discretionary sales to exceed 5% of the shares of our Class B common stock to be offered.

S-10

Underwriting

The following table shows the per share and total underwriting discounts and commissions we will pay to the underwriter assuming both no exercise and full exercise of the underwriter’s option to purchase up to an additional 2,700,000 shares.

We estimate that the total expenses of this offering paid and payable by us, not including the underwriting discounts and commissions, will be approximately $150,000.

No sales of similar securities

We and certain of our executive officers have entered into lock-up agreements with the underwriter. Under the agreement, subject to exceptions specified in the agreement, we and certain of our executive officers may not, without the prior written approval of UBS Securities LLC, offer, sell, contract to sell or otherwise dispose of, directly or indirectly, our Class B common stock or securities convertible into or exchangeable for or exercisable for our Class B common stock. These restrictions will be in effect for a period of 60 days from October 19, 2005. At any time and without public notice, UBS Securities LLC may, in its sole discretion, release some or all of the securities from the lock-up agreement.

Price stabilization and short positions

In connection with this offering, the underwriter may engage in activities that stabilize, maintain or otherwise affect the price of our Class B common stock, including:

Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of our Class B common stock while this offering is in progress. These transactions may also include making short sales of our Class B common stock, which involve the sale by the underwriter of a greater number of shares of Class B common stock than it is required to purchase in this offering. Short sales may be “covered short sales,” which are short positions in an amount not greater than the underwriter’s over-allotment option referred to above, or may be “naked short sales,” which are short positions in excess of that amount.

The underwriter may close out any covered short position either by exercising its over-allotment option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriter will consider, among other things, the price of shares available for purchase in the open market compared to the price at which it may purchase shares through the over-allotment option. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the Class B common stock in the open market that could adversely affect investors who purchased in this offering.

As a result of these activities, the price of our Class B common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriter at any time. The underwriter may carry out these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise.

DESCRIPTION OF DEBT SECURITIES

      The following description sets forth certain general terms and provisions of our debt securities, consisting of notes, debentures or other evidences of indebtedness, that we may offer by this prospectus. We will describe the particular terms of debt securities, and provisions that vary from those described below, in one or more prospectus supplements.

      We may offer under this prospectus up to $1.0 billion total principal amount of debt securities, or its equivalent if debt securities are issued at a discount or in a foreign currency or currency units. We may issue the debt securities in registered or bearer form. The debt securities we offer pursuant to this prospectus will be unsecured obligations unless otherwise specified in the applicable prospectus supplement. We may issue the debt securities as unsubordinated or senior debt securities, or as subordinated debt securities. The senior debt securities will rank equally in right of payment with all our current and future unsubordinated indebtedness, and the subordinated debt securities will be subordinated in right of payment to all our senior indebtedness, as described below under “— Subordination of Subordinated Debt Securities.”

      As required by U.S. law, debt securities are governed by a document called an “indenture.” The indenture is a contract between us and an entity named in this prospectus or a prospectus supplement which acts as trustee. The trustee has two main roles:

      Senior debt securities will be issued under a senior debt indenture entered into between us and J. P. Morgan Trust Company, National Association (as successor in interest to Bank One, N.A.), as trustee, dated as of July 15, 1997. Subordinated debt securities will be issued under a subordinated debt indenture between us and a trustee we name when the subordinated debt securities are issued. The senior debt indenture and the subordinated debt indenture are sometimes collectively referred to in this prospectus as the “indentures.” We have filed the senior indenture and a form of the subordinated indenture as exhibits to this registration statement of which this prospectus is a part.

      The following description is a summary of selected provisions relating to the debt securities and the indentures. The summary is not complete. You should not rely on this summary, because the indentures define your rights as a holder of the debt securities.

General

      The indentures do not limit the total principal amount of debt securities that may be issued and provide that debt securities may be issued from time to time in one or more series. We will set forth in a prospectus supplement a description of the series of debt securities being offered, including some or all of the following:

      The holders of our debt securities (whether senior or subordinated debt securities) will be effectively subordinated to the creditors of our subsidiaries because such creditors will have a direct claim against any assets of such subsidiaries upon their liquidation or reorganization. By contrast, as a holder of our debt securities (whether senior or subordinated debt securities), you will have only an indirect claim against the assets of our subsidiaries that derives through our ownership of the capital stock of our subsidiaries. Consequently, as a holder of debt securities, your right to participate in those assets will be effectively subordinated to the claims of that subsidiary’s creditors (including trade creditors). In addition, the holders of our debt securities (whether senior or subordinated debt securities) will be effectively subordinated to the holders of our secured debt to the extent of the collateral securing such debt.

      Except as may be set forth in a prospectus supplement, the indentures also do not limit the aggregate amount of unsecured indebtedness that we or our subsidiaries may incur.

      Unless we indicate differently in a prospectus supplement, the debt securities will not be listed on any securities exchange and will be issued in fully registered form without coupons. If debt securities are issued in bearer form, we will set forth the special restrictions and considerations applicable to such debt securities in a prospectus supplement. Bearer debt securities will be transferable by delivery of the security by the transferring holder to the new holder, and the transfer will not be registered or recorded by the trustee or us.

      We may sell the debt securities for an amount less than their stated principal amount, bearing no interest or bearing a below market rate of interest. We will provide you with information on the federal income tax consequences and other special considerations applicable to any of these debt securities in a prospectus supplement.

      If the purchase price of any debt securities is payable in one or more foreign currencies or currency units or if any debt securities are denominated in one or more foreign currencies or currency units or if the principal of, premium and/or interest, if any, on any debt securities is payable in one or more foreign currencies or currency units, the restrictions, elections, federal income tax considerations, specific terms and other information with respect to the debt securities and such foreign currency or currency units will be set forth in a prospectus supplement.

Denominations, Payment, Registration, Transfer and Exchange

      We will issue registered debt securities in denominations of $1,000 and multiples of $1,000, and we will issue bearer debt securities in $5,000 denominations or, in each case, in such other denominations and currencies established by the terms of the debt securities of any particular series. Unless we provide otherwise in a prospectus supplement, we will make payments in respect of the debt securities, subject to any applicable laws and regulations, in the designated currency and at the office or agency as we may designate from time to time. At our option, however, we may make interest payments on debt securities in registered form:

      We will pay installments of interest on debt securities:

      The paying agents outside the United States, if any, whom we initially appoint for a series of debt securities will be named in a prospectus supplement. We may at any time designate additional paying agents or rescind the designation of any paying agents, provided that, in the case of:

      We will have the right to require a holder of any debt security, in connection with the payment of the principal of, premium and/or interest, if any, on any debt security, to certify certain information to us for tax purposes. In the absence of such certification, we will be entitled to rely on any legal presumption to enable us to determine our duties and liabilities, if any, to deduct or withhold taxes, assessments or governmental charges from such payment.

      Unless we provide otherwise in a prospectus supplement, you may transfer debt securities in registered form at the agency we designate from time to time. You will not be required to pay a service charge to transfer or exchange the debt securities, but you may be required to pay for any tax or other governmental charge imposed in connection with the transfer or exchange.

      If we redeem the debt securities of any series, we will not be required to:

Subordination of Subordinated Debt Securities

      Unless otherwise indicated in the applicable prospectus supplement, the following provisions will apply to the subordinated debt securities.

      The payment of the principal of, premium, and/or interest, if any, on, and the redemption or repurchase of, the subordinated debt securities and coupons will be subordinated and junior in right of payment, as set forth in the subordinated indenture, to the prior payment in full of all our “senior indebtedness” (as defined below). Generally, the subordinated debt securities will rank equally in right of payment with all of our existing and future subordinated indebtedness other than any future subordinated indebtedness or other subordinated obligations which we specify will rank junior to the subordinated debt

securities. Notwithstanding the preceding, payment from the money or the proceeds of U.S. government obligations held in any defeasance trust described under “— Defeasance; Satisfaction and Discharge” below is not subordinate to any senior indebtedness or subject to the restrictions described herein.

      Senior indebtedness consists of the following types of obligations, in each case subject to the exceptions enumerated below:

      Except as set forth in the applicable prospectus supplement, senior indebtedness will not include the following:

      The senior indebtedness will continue to be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of the senior indebtedness. Except as set forth in the applicable prospectus supplement, the payment of the principal of, premium, if any, and interest, if any, on the subordinated debt securities and coupons will rank senior in right of payment to our guarantee of certain payments under the 6% Convertible Preferred Securities, Term Income Deferrable Equity Securities (TIDES) of Continental Airlines Finance Trust II and our 6% Convertible Junior Subordinated Debentures due 2030.

      No payment on account of principal of, premium, if any, or interest on, or redemption or repurchase of, the subordinated debt securities or any coupon or any deposit pursuant to the provisions described under “— Defeasance; Satisfaction and Discharge” below may be made by us if there is a default in the payment of principal, premium, if any, sinking funds or interest (including a default under any repurchase or redemption obligation) or other amounts with respect to any senior indebtedness. Similarly, no payment may be made if any other event of default with respect to any senior indebtedness, permitting the holders of senior indebtedness to accelerate the maturity thereof, has occurred and has not been cured, waived or ceased to exist after written notice to us and the trustee by any holder of senior indebtedness. Upon any

acceleration of the principal due on the subordinated debt securities or payment or distribution of our assets to creditors upon any dissolution, winding up, liquidation or reorganization, all principal, premium, if any, sinking funds and interest or other amounts due on all senior indebtedness must be paid in full before the holders of the subordinated debt securities are entitled to receive any payment. Because of such subordination, if we become insolvent, our creditors who are holders of senior indebtedness may recover more, ratably, than the holders of the subordinated debt securities. Furthermore, such subordination may result in a reduction or elimination of payments to the holders of the subordinated debt securities.

      The subordinated indenture does not limit our ability to incur senior indebtedness or any other indebtedness.

Global Debt Securities

      The debt securities of a series may be issued in whole or in part in global form that will be deposited with a depositary or with a nominee for the depositary identified in a prospectus supplement. In such case, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the total principal amount of outstanding debt securities of the series to be represented by such registered global security or securities. Unless and until it is exchanged in whole or in part for debt securities in definitive form, a registered global security may not be registered for transfer or exchange except as a whole by the depositary, the depositary’s nominee or their respective successors as described in the applicable prospectus supplement.

      The specific terms of the depositary arrangement with respect to any portion of a series of debt securities to be represented by a registered global security will be described in a prospectus supplement. We expect that the following provisions will apply to depositary arrangements.

      Upon the issuance of any registered global security, and the deposit of such security with or on behalf of the appropriate depositary, the depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of the debt securities represented by such registered global security to the accounts of institutions or participants that have accounts with the depositary or its nominee. The accounts to be credited will be designated by the underwriters or agents engaging in the distribution of the debt securities or by us, if we offer and sell such debt securities directly.

      Ownership of beneficial interests in a registered global security will be limited to participants of the depositary (which are usually large investment banks, retail brokerage firms, banks and other large financial institutions) and persons that hold interests through participants. Ownership of beneficial interests by participants in a registered global security will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by the depositary for that security or its nominee. Ownership of beneficial interests in a registered global security by persons who hold through participants will be shown on, and the transfer of those ownership interests within that participant will be effected only through, records maintained by that participant. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in certificated form. The preceding limitations and such laws may impair the ability to transfer beneficial interests in registered global securities.

      So long as the depositary for a registered global security, or its nominee, is the registered owner of a registered global security, that depositary or nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by that registered global security. Unless otherwise specified in a prospectus supplement and except as specified below, owners of beneficial interests in a registered global security will not:

      Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indentures.

      The depositary may grant proxies and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a holder is entitled to give or take under the indentures. Unless otherwise specified in a prospectus supplement, payments with respect to principal, premium and/or interest, if any, on debt securities represented by a registered global security registered in the name of a depositary or its nominee will be made to such depositary or its nominee, as the case may be, as the registered owner of such registered global security.

      We expect that the depositary for any debt securities represented by a registered global security, upon receipt of any payment of principal, premium or interest, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the registered global security as shown on the records of such depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing instructions and customary practices in the securities industry, as is now the case with the securities held for the accounts of customers registered in “street names,” and will be the responsibility of such participants. Neither we nor the trustee or any agent of ours will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a registered global security, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

      Unless otherwise specified in a prospectus supplement, if the depositary for any debt securities represented by a registered global security is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by us within 90 days, we will issue debt securities in certificated form in exchange for the registered global security. In addition, the indentures provide that we may at any time and in our sole discretion determine not to have any of the debt securities of a series represented by one or more registered global securities and, in such event, will issue debt securities of such series in certificated form in exchange for all of the registered global securities representing such debt securities. Further, if we so specify with respect to the debt securities of a series, an owner of a beneficial interest in a registered global security representing such series of debt securities may receive, on terms acceptable to us and the depositary for such registered global security, debt securities of such series in certificated form registered in the name of such beneficial owner or its designee.

Consolidation, Merger and Conveyance of Assets as an Entirety

      Each indenture provides that we will not merge or consolidate with or into any other entity or sell, convey, transfer, lease or otherwise dispose of all or substantially all our assets unless:

      If a successor corporation assumes our obligations, the successor will succeed to and be substituted for us under the indentures, the debt securities and any related coupons. Consequently, all of our obligations will terminate, except in the case of a lease. If any such permitted consolidation, merger, sale, conveyance, disposition or other change of control transaction occurs, the holders of the debt securities will not have

the right to require redemption of their securities or similar rights unless otherwise provided in a prospectus supplement.

Events of Default

      An “Event of Default” occurs with respect to debt securities of any series if any of the following occurs:

      An Event of Default with respect to a particular series of debt securities will not necessarily be an Event of Default with respect to any other series of debt securities.

      The indentures provide that, if an Event of Default occurs with respect to the debt securities of any series and is continuing, the trustee for the series or the holders of 25% in aggregate principal amount of all of the outstanding debt securities of that series, by written notice to us (and to the trustee for such series, if notice is given by the holders of debt securities), may declare the principal (or, if the debt securities of that series are original issue discount debt securities or indexed debt securities, such portion of the principal amount specified in the prospectus supplement) of all the debt securities of that series to be due and payable.

      The indentures provide that the trustee for any series of debt securities will give to the holders of the debt securities of that series notice of all uncured Defaults (as defined below) within 90 days after the occurrence of a Default. However, such notice will not be given until 60 days after the occurrence of a Default with respect to the debt securities of that series involving a failure to perform a covenant other than the obligation to pay principal, premium, and/or interest, if any, or make a mandatory sinking fund payment. Further, except in the case of default in payment on the debt securities of that series, the trustee may withhold the notice if and so long as a committee comprised of certain officers of the trustee determines in good faith that withholding such notice is in the interests of the holders of the debt securities of that series. “Default” means any event which is, or, after notice or passage of time or both, would be, an Event of Default.

      Under the indentures, the trustee is under no obligation to exercise any of its rights or powers at the request of any of the holders, unless such holders have offered to the trustee reasonable indemnity. Subject to such provision for indemnification, the indentures provide that the holders of not less than a majority in aggregate principal amount of the debt securities of each series affected with each series voting as a class, may direct the time, method and place of conducting any proceeding for any remedy available to the trustee for such series, or exercising any trust or power conferred on such trustee. We are required to file annually with the trustee a certificate as to our compliance with all conditions and covenants under indentures.

      By notice to the trustee, the holders of not less than a majority in total principal amount of any series of debt securities may waive any past Default or Event of Default with respect to that series and its consequences, except a Default or an Event of Default based on the payment of the principal of, premium,

if any, or interest, if any, on any debt security of a series and certain other defaults. Further, such majority holders may rescind and annul a declaration of acceleration with respect to that series (unless a judgment or decree based on such acceleration has been obtained by the trustee), if all existing Defaults and Events of Default with respect to that series (other than the non-payment of the principal of that series that has become due solely by the declaration of acceleration) have been cured or waived.

Modification of Indenture

      Without Holder Consent. Without the consent of any holders of debt securities, we and the trustee may enter into one or more supplemental indentures for any of the following purposes:

      With Holder Consent. Except as provided above, the consent of the holders of a majority in aggregate principal amount of the debt securities of each series affected by such supplemental indenture is generally required for the purpose of adding to, or changing or eliminating any of the provisions of, the indentures or debt securities pursuant to a supplemental indenture. However, no amendment may, without the consent of the holder of each outstanding debt security directly affected thereby,

      A supplemental indenture which changes or eliminates any provision of the indenture expressly included solely for the benefit of holders of debt securities of one or more particular series of debt securities will be deemed not to affect the rights under the indenture of the holders of debt securities of any other series.

Defeasance; Satisfaction and Discharge

      If indicated in the applicable prospectus supplement, we will have two options to discharge our obligations under a series of debt securities before their stated maturity date. We may elect either:

      To elect either option, we must deposit with the trustee for such series an amount of money and/or government obligations sufficient to pay the principal of, premium and/or interest, if any, on such debt securities to stated maturity or redemption, as the case may be, and any mandatory sinking fund payments.

      Upon the occurrence of a defeasance, we will be deemed to have paid and discharged the entire indebtedness represented by the debt securities of or within any series and any related coupons and to have satisfied all of our other obligations with respect to such debt securities and coupons, except for:

      Upon the occurrence of a covenant defeasance, we will:

      Unless otherwise specified in the applicable prospectus supplement and except as described below, the conditions to both defeasance and covenant defeasance are as follows:

      A nationally recognized firm of independent public accountants must deliver a written certification to the trustee as to the sufficiency of the trust funds deposited for the defeasance or covenant defeasance of the debt securities. As holders of the debt securities, you will not have any recourse against such firm. If government obligations deposited with the trustee for the defeasance of the debt securities decrease in value or default subsequent to their being deposited, we will have no further obligation, and you will have no additional recourse against us, as a result of such decrease in value or default.

      We may exercise our defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our defeasance option, payment of the debt securities may not be accelerated

because of an Event of Default. If we exercise our covenant defeasance option, payment of the debt securities may not be accelerated by reason of an Event of Default with respect to the covenants to which such covenant defeasance is applicable. However, if such acceleration were to occur, the realizable value at the acceleration date of the money and government obligations in the defeasance trust could be less than the principal and interest, if any, then due on the defeased debt securities, because the required deposit in the defeasance trust is based upon scheduled cash flow rather than market value, which will vary depending upon interest rates and other factors.

      A prospectus supplement may further describe the provisions, if any, applicable to defeasance or covenant defeasance with respect to debt securities of or within a particular series.

      In addition, we may satisfy and discharge either indenture with respect to any series of debt securities and as a result we will be relieved of our obligations with respect to the debt securities of that series, other than our obligations with respect to registration of transfer and exchange of such debt securities and the replacement of lost, stolen or mutilated debt securities, provided that either:

The Trustee

      The trustee under the senior debt indenture is J. P. Morgan Trust Company, National Association (as successor in interest to Bank One, N.A.). The trustee under the subordinated debt indenture will be named when the subordinated debt securities are issued. If more than one series of debt securities is outstanding under an indenture, a trustee may serve as trustee with respect to the debt securities of one or more of such series. If more than one series of debt securities is outstanding under an indenture, the holders of a majority in total principal amount of each such series at any time outstanding may remove the trustee with respect to such series (but not as to any other series) by notifying the trustee and us and may appoint a successor trustee for such series with our consent.

      Each indenture contains certain limitations on the right of the trustee, should it become a creditor of ours, to obtain payment of claims in certain cases, or to realize for its own account on certain property received in respect of any such claim as security or otherwise. The trustee is permitted to engage in certain other transactions; however, if after an Event of Default has occurred and is continuing, the trustee acquires any conflicting interest (as specified in the Trust Indenture Act of 1939) it must eliminate such conflict or resign.

Governing Law

      The indentures and the debt securities will be governed by the laws of the State of New York.

DESCRIPTION OF COMMON STOCK AND PREFERRED STOCK

      Our authorized capital stock currently consists of 200 million shares of Class B common stock, which we refer to as the common stock, and 10 million shares of preferred stock. As of August 31, 2005, we had outstanding 67,048,822 shares of Class B common stock and one share of Series B preferred stock.

      This section contains a description of our common stock and preferred stock that we may offer by this prospectus as well as the terms of our Series B preferred stock which may affect our common stock and preferred stock that we may offer by this prospectus. The following discussion is not meant to be complete and is qualified by reference to our certificate of incorporation, bylaws and the rights agreement that we describe in this section. For more information, you should read “Where You Can Find More Information.”

Description of Common Stock

      Rights to Dividends and on Liquidation, Dissolution or Winding Up. Common stockholders participate ratably in any dividends or distributions on the common stock. In the event of any liquidation, dissolution or winding up of our company, common stockholders are entitled to share ratably in our assets available for distribution to the stockholders, subject to the prior rights of holders of any outstanding preferred stock.

      Preemptive and Other Subscription Rights. Common stockholders do not have preemptive, subscription, conversion or redemption rights, and are not subject to further capital calls or assessments.

      No Cumulative Voting Rights. Common stockholders do not have the right to cumulate their votes in the election of directors.

      Voting. Holders of common stock are entitled to one vote per share on all matters submitted to a vote of stockholders, except that voting rights of non-U.S. citizens are limited as described under “— Limitation on Voting by Foreign Owners.”

Description of Preferred Stock

      The following summary describes certain general terms of our authorized preferred stock.

      We may issue preferred stock from time to time in one or more series. Subject to the provisions of our certificate of incorporation and limitations prescribed by law, our board of directors may adopt resolutions to issue the shares of preferred stock in one or more series, to fix the number of shares of the series and to establish the designations, powers, preferences and relative, participating, optional or other special rights of the preferred stock. Our board of directors may also fix the qualifications, limitations or restrictions, if any, of the preferred stock, including dividend rights (including whether dividends are cumulative), dividend rates, terms of redemption (including sinking fund provisions), redemption rights and prices, conversion or exchange rights and liquidation preferences of the shares of the series, in each case without any further action or vote by our stockholders.

      If we offer preferred stock, a description will be filed with the SEC and the specific terms of the preferred stock will be described in the prospectus supplement, including the following terms:

Limitation on Voting by Foreign Owners

      Our certificate of incorporation provides that shares of capital stock may not be voted by or at the direction of persons who are not citizens of the United States unless the shares are registered on a separate stock record. Applicable restrictions currently require that no more than 25% of our voting stock be owned or controlled, directly or indirectly, by persons who are not U.S. citizens, and that our president and at least two-thirds of our directors or other managing officers be U.S. citizens. For purposes of the certificate of incorporation, “U.S. citizen” means:

      Our bylaws provide that no shares will be registered on the foreign stock record if the amount so registered would exceed the restrictions described above or adversely affect our operating certificates or authorities. Registration on the foreign stock record is made in chronological order based on the date we receive a written request for registration.

Preferred Stock Purchase Rights

      General. One preferred stock purchase right is currently associated with each outstanding share of our common stock. Each of these preferred stock purchase rights entitles the registered holder to purchase from us one one-thousandth of a share of our Series A junior participating preferred stock at a purchase price of $200 per one one-thousandth of a share, subject to adjustment.

      The preferred stock purchase rights will have anti-takeover effects. The preferred stock purchase rights could cause substantial dilution to a person or group that attempts to acquire us and effect a change in the composition of our board of directors on terms not approved by our board of directors, including by means of a tender offer at a premium to the market price. Subject to restrictions and limitations contained in our charter, the preferred stock purchase rights should not interfere with any merger or business combination approved by our board of directors, because we may redeem the preferred stock purchase rights at the redemption price prior to the time that a person has become an acquiring person or amend the preferred stock purchase rights to make them inapplicable to the approved transaction.

      The following summary of the material terms of the preferred stock purchase rights is not meant to be complete and is qualified by reference to the rights agreement that governs the issuance of the rights. See “Where You Can Find More Information.”

      Evidence and Transferability of Preferred Stock Purchase Rights. The preferred stock purchase rights will be evidenced by the certificates representing shares of common stock until the earlier to occur of:

      Until the rights distribution date or the earlier redemption or expiration of the preferred stock purchase rights:

      As soon as practicable following the rights distribution date, separate certificates evidencing the preferred stock purchase rights will be mailed to holders of record of the shares of common stock as of the close of business on the rights distribution date and those separate preferred stock purchase rights certificates alone will evidence the rights.

      Exempt Persons. We and certain persons affiliated with us are exempt from the definition of acquiring person. An exception to the definition of acquiring person in the rights agreement permits an institutional investor to be or become the beneficial owner of our common stock representing 15% or more of the voting power of the common stock then outstanding, subject to certain limitations described below, without becoming an acquiring person, as long as the institutional investor continues to be an institutional investor. Generally, an institutional investor is a person who, as of January 31, 2000:

      If our board of directors determines that a person is no longer an institutional investor, then this person will be required to divest itself as promptly as practicable of a sufficient number of shares of common stock so that this person beneficially owns less than 15% of the voting power of our common stock then outstanding.

      If our board of directors determines that this person does not divest itself of common shares as required, then this person will be or become an acquiring person under the rights agreement.

      Exercisability of Rights. The preferred stock purchase rights are not exercisable until the preferred stock purchase rights distribution date. The preferred stock purchase rights will expire on November 20, 2008, unless the expiration date is extended or unless the preferred stock purchase rights are earlier redeemed or exchanged by us, in each case, as described below.

      If any person becomes an acquiring person, each holder of a preferred stock purchase right (other than preferred stock purchase rights beneficially owned by the acquiring person, which will be void) will, after the date that any person became an acquiring person, have the right to receive, upon exercise of

those preferred stock purchase rights at the then current exercise price, that number of shares of common stock, or cash or other securities or assets in certain circumstances, having a market value of two times the exercise price of the preferred stock purchase right. If, at any time on or after the date that any person has become an acquiring person, we are acquired in a merger or other business combination transaction or 50% or more of our consolidated assets or earning power are sold, each holder of a preferred stock purchase right will, after the date of that transaction, have the right to receive, upon the exercise of those preferred stock purchase rights at the then current exercise price of the preferred stock purchase right, that number of shares of common stock of the acquiring company which at the time of that transaction will have a market value of two times the exercise price of the preferred stock purchase right.

      The purchase price payable, and the number of shares of junior preferred stock or other securities or property issuable, upon exercise of the preferred stock purchase rights are subject to adjustment from time to time to prevent dilution in some circumstances.

      Until a preferred stock purchase right is exercised, the holder of a preferred stock purchase right will have no rights as a stockholder of our company, including the right to vote or to receive dividends.

      From and after the occurrence of an event described in Section 11(a)(ii) of the rights agreement, if rights are or were, at any time on or after the earlier of (1) the date of such event and (2) the distribution date, acquired or beneficially owned by an acquiring person or an associate or affiliate of an acquiring person, such rights shall become void, and any holder of such rights shall thereafter have no right to exercise such rights.

      Terms of Junior Preferred Stock. Shares of junior preferred stock, which may be purchased upon exercise of the preferred stock purchase rights, will not be redeemable. Each share of junior preferred stock will be entitled to receive when, as and if declared by the board of directors, out of funds legally available for the purpose, an amount per share equal to 1,000 times the cash or non-cash dividend declared per share of common stock. In the event of liquidation, the holders of the junior preferred stock will be entitled to receive an aggregate payment equal to 1,000 times the payment made per share of common stock. Each share of junior preferred stock will have 1,000 votes, together with the common stock. Finally, in the event of any merger, consolidation or other transaction in which the common stock is exchanged, each share of junior preferred stock will be entitled to receive an amount equal to 1,000 times the amount received per share of common stock. The rights are protected by customary antidilution provisions.

      Exchange or Redemption. At any time after any person becomes an acquiring person, and prior to the acquisition by any person or group of a majority of the voting power, our board of directors may exchange the rights (other than rights owned by such acquiring person which have become void), in whole or in part, at an exchange ratio of one share of common stock per right (subject to adjustment). We may, at our option, substitute preferred shares or common stock equivalents for common stock, at the rate of one one-thousandth of a preferred share for each share of common stock (subject to adjustment). No fractional share of common stock will be issued and in lieu thereof, an adjustment in cash will be made based on the market price of the share of common stock on the last trading day prior to the date of exchange.

      At any time prior to any person becoming an acquiring person, our board of directors, by the required board vote, may redeem the rights in whole, but not in part, at a redemption price of $.001 per right. The redemption of the rights may be made effective at the time, on any basis and subject to the conditions which our board of directors may establish. Immediately upon any redemption of the rights (or upon a later date specified by our board of directors in the resolution approving a redemption), the right to exercise the rights will terminate and the only right of the holders of rights will be to receive the redemption price. The redemption of the rights may be subject to certain restrictions and limitations contained in our charter.

      Our board of directors, by the required board vote, may amend the terms of the rights without the consent of the holders of the rights, except that from the time any person becomes an acquiring person, no amendment may adversely affect the interests of the holders of the rights (other than the acquiring person

and its affiliates and associates). The right of our board of directors to amend the rights agreement may be subject to certain restrictions and limitations contained in our charter.

Series B Preferred Stock

      We have one outstanding share of Series B preferred stock, which is owned by Northwest Airlines, Inc. Set forth below is a description of some of the material provisions of the Series B preferred stock.

      Ranking. The Series B preferred stock ranks junior to all classes of our capital stock other than our common stock upon liquidation, dissolution or winding up of our company.

      Dividends. No dividends are payable on our Series B preferred stock.

      Voting Rights. The holder of the Series B preferred stock has the right to block certain actions we may seek to take, including:

      Redemption. The Series B preferred stock is redeemable by us at a nominal price under the following circumstances:

Corporate Governance and Control

      Our certificate of incorporation provides that our board of directors will consist of a number of directors as may be determined from time to time by the board of directors in accordance with the bylaws. Our board of directors currently consists of 11 directors elected by common stockholders, subject to the rights of preferred stockholders to elect additional directors as set forth in any preferred stock designations.

Business Combinations

      Our certificate of incorporation provides that we are not governed by Section 203 of the General Corporation Law of Delaware which, in the absence of such provisions, would have imposed additional requirements regarding mergers and other business combinations.

Procedural Matters

      Our bylaws require stockholders seeking to nominate directors or propose other matters for action at a stockholders’ meeting to give us notice within specified periods in advance of the meeting and to follow certain other specified procedures.

Change of Control

      Because a separate class vote is required pursuant to the terms of the Series B preferred stock in connection with some changes of control requiring stockholder approval as described under “— Series B Preferred Stock — Voting Rights,” a change of control of our company could be delayed, deferred or prevented.

      In addition, the existence of the preferred stock purchase rights may have the effect of delaying or preventing a change of control of our company. See “— Preferred Stock Purchase Rights” above.

Limitation of Director Liability and Indemnification

      Our certificate of incorporation provides, to the full extent permitted by Delaware law, that directors will not be liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director. As required under current Delaware law, our certificate of incorporation and bylaws currently provide that this waiver may not apply to liability:

      However, in the event the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of any of our directors will be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended. Our certificate of incorporation further provides that we will indemnify each of our directors and officers to the full extent permitted by Delaware law and may indemnify certain other persons as authorized by the Delaware General Corporation Law. These provisions do not eliminate any monetary liability of directors under the federal securities laws.

DESCRIPTION OF DEPOSITARY SHARES

      We may offer fractional shares of preferred stock, rather than full shares of preferred stock. If we decide to offer fractional shares of preferred stock, we will issue receipts for depositary shares. Each depositary share will represent a fraction of a share of a particular series of preferred stock, and the prospectus supplement will indicate that fraction. The shares of preferred stock represented by depositary shares will be deposited under a deposit agreement between our company and a depositary that is a bank or trust company that meets certain requirements and is selected by us. The depositary will be specified in the applicable prospectus supplement. Each owner of a depositary share will be entitled to all of the rights and preferences of the preferred stock represented by the depositary share. The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of preferred stock in accordance with the terms of the offering.

      We have summarized selected provisions of the deposit agreement and the depositary receipts, but the summary is qualified by reference to the provisions of the deposit agreement and the depositary receipts. The particular terms of any series of depositary shares will be described in the applicable prospectus supplement. If so indicated in the prospectus supplement, the terms of any such series may differ from the terms set forth below.

Dividends

      The depositary will distribute all cash dividends or other cash distributions received by it in respect of the preferred stock to the record holders of depositary shares relating to such preferred shares in proportion to the numbers of depositary shares held on the relevant record date. The amount made available for distribution will be reduced by any amounts withheld by the depositary or us on account of taxes.

      In the event of a distribution other than in cash, the depositary will distribute securities or property received by it to the record holders of depositary shares in proportion to the numbers of depositary shares held on the relevant record date, unless the depositary determines that it is not feasible to make such distribution. In that case, the depositary may make the distribution by such method as it deems equitable and practicable. One such possible method is for the depositary to sell the securities or property and then distribute the net proceeds from the sale as provided in the case of a cash distribution.

Withdrawal of Shares

      Upon surrender of depositary receipts representing any number of whole shares at the depositary’s office, unless the related depositary shares previously have been called for redemption, the holder of the depositary shares evidenced by the depositary receipts will be entitled to delivery of the number of whole shares of the related series of preferred stock and all money and other property, if any, underlying such depositary shares. However, once such an exchange is made, the preferred stock cannot thereafter be redeposited in exchange for depositary shares. Holders of depositary shares will be entitled to receive whole shares of the related series of preferred stock on the basis set forth in the applicable prospectus supplement. If the depositary receipts delivered by the holder evidence a number of depositary shares representing more than the number of whole shares of preferred stock of the related series to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares.

Redemption of Depositary Shares

      Whenever we redeem the preferred stock, the depositary will redeem a number of depositary shares representing the same number of shares of preferred stock so redeemed. If fewer than all of the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot, pro rata or by any other equitable method as the depositary may determine.

Voting of Underlying Shares

      Upon receipt of notice of any meeting at which the holders of the preferred stock of any series are entitled to vote, the depositary will mail the information contained in the notice of the meeting to the record holders of the depositary shares relating to that series of preferred shares. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights represented by the number of shares of preferred stock underlying the holder’s depositary shares. The depositary will endeavor, to the extent it is practical to do so, to vote the number of whole shares of preferred stock underlying such depositary shares in accordance with such instructions. We will agree to take all action that the depositary may deem reasonably necessary in order to enable the depositary to do so. To the extent the depositary does not receive specific instructions from the holders of depositary shares relating to such preferred shares, it will abstain from voting such shares of preferred stock.

Amendment and Termination of Deposit Agreement

      The form of depositary receipt evidencing the depositary shares and any provision of the applicable deposit agreement may at any time be amended by agreement between us and the depositary. We may, with the consent of the depositary, amend the deposit agreement from time to time in any manner that we desire. However, if the amendment would materially and adversely alter the rights of the existing holders

of depositary shares, the amendment would need to be approved by the holders of at least a majority of the depositary shares then outstanding.

      The deposit agreement may be terminated by us or the depositary if:

Resignation and Removal of Depositary

      The depositary may resign at any time by delivering to us notice of its election to do so. We may remove a depositary at any time. Any resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of appointment.

Charges of Depositary

      We will pay all transfer and other taxes and governmental charges arising solely from the existence of any depositary arrangements. We will pay all charges of each depositary in connection with the initial deposit of the preferred shares of any series, the initial issuance of the depositary shares, any redemption of such preferred shares and any withdrawals of such preferred shares by holders of depositary shares. Holders of depositary shares will be required to pay any other transfer taxes.

Notices

      Each depositary will forward to the holders of the applicable depositary shares all notices, reports and communications from us which are delivered to such depositary and which we are required to furnish the holders of the preferred shares.

Limitation of Liability

      The deposit agreement contains provisions that limit our liability and the liability of the depositary to the holders of depositary shares. Both the depositary and we are also entitled to an indemnity from the holders of the depositary shares prior to bringing, or defending against, any legal proceeding. We or any depositary may rely upon written advice of counsel or accountants, or information provided by persons presenting preferred shares for deposit, holders of depositary shares or other persons believed by us or it to be competent and on documents believed by us or them to be genuine.

DESCRIPTION OF WARRANTS

      We may issue warrants to purchase any of our securities. We may issue warrants independently or together with any other securities offered by any prospectus supplement and the warrants may be attached to or separate from those securities. Each series of warrants will be issued under a separate warrant agreement, to be entered into between us and a warrant agent specified in a prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency or trust with any of the holders of the warrants. We will set forth further terms of the warrants and the applicable warrant agreements in the applicable prospectus supplement relating to the issuance of any warrants, including, where applicable, the following:

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

      We may issue stock purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified number of shares of common stock or other securities at a future date or dates, which we refer to in this prospectus as “stock purchase contracts.” The price per share of the securities and the number of shares of the securities may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. The stock purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and debt securities, preferred securities, warrants or debt obligations of third parties, including U.S. treasury securities, securing the holders’ obligations to purchase the securities under the stock purchase contracts, which we refer to herein as “stock purchase units.” The stock purchase contracts may require holders to secure their obligations under the stock purchase contracts in a specified manner. The stock purchase contracts also may require us to make periodic payments to the holders of the stock purchase units or vice versa, and those payments may be unsecured or refunded on some basis.

      The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units. The description in the prospectus supplement will not necessarily be complete, and reference will be made to the stock purchase contracts, and, if applicable, collateral or depositary arrangements, relating to the stock purchase contracts or stock purchase units, which will be filed with the SEC each time we issue stock purchase contracts or stock purchase units. Material United States federal income tax considerations applicable to the stock purchase units and the stock purchase contracts will also be discussed in the applicable prospectus supplement.

DESCRIPTION OF SUBSCRIPTION RIGHTS

General

      We may issue subscription rights to purchase common stock, preferred stock, depositary shares or warrants to purchase preferred stock, common stock or depositary shares. Subscription rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any subscription rights offering to our stockholders, we may enter into a standby underwriting arrangement with one or more underwriters pursuant to which such underwriters will purchase any offered securities remaining unsubscribed for after such subscription rights offering. In connection with a subscription rights offering to our stockholders, we will distribute certificates evidencing the subscription rights and a prospectus supplement to our stockholders on the record date that we set for receiving subscription rights in such subscription rights offering.

      The applicable prospectus supplement will describe the following terms of subscription rights in respect of which this prospectus is being delivered:

Exercise of Subscription Rights

      Each subscription right will entitle the holder of the subscription right to purchase for cash such amount of shares of preferred stock, depositary shares, common stock, warrants or any combination thereof, at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the subscription rights offered thereby. Subscription rights may be exercised at any time up to the close of business on the expiration date for such subscription rights set forth in the prospectus supplement. After the close of business on the expiration date, all unexercised subscription rights will become void.

      Subscription rights may be exercised as set forth in the prospectus supplement relating to the subscription rights offered thereby. Upon receipt of payment and the subscription rights certificate properly completed and duly executed at the corporate trust office of the subscription rights agent or any other office indicated in the prospectus supplement, we will forward, as soon as practicable, the shares of preferred stock or common stock, depositary shares or warrants purchasable upon such exercise. We may determine to offer any unsubscribed offered securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as set forth in the applicable prospectus supplement.

PLAN OF DISTRIBUTION

      Any of the securities being offered hereby and any accompanying prospectus supplement may be sold in any one or more of the following ways from time to time:

      In addition, we may issue the securities as a dividend or distribution to our stockholders.

      The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

      We may solicit offers to purchase directly. Offers to purchase securities also may be solicited by agents designated by us from time to time. Any such agent involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the applicable prospectus supplement. Unless otherwise indicated in such prospectus supplement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment. Any such agent may be deemed to be an underwriter, as that term is defined in the Securities Act of 1933, of the securities so offered and sold.

      If securities are sold by means of an underwritten offering, we will execute an underwriting agreement with an underwriter or underwriters at the time an agreement for such sale is reached, and the names of the specific managing underwriter or underwriters, as well as any other underwriters, the respective amounts underwritten and the terms of the transaction, including commissions, discounts and any other compensation of the underwriters and dealers, if any, will be set forth in the applicable prospectus supplement which will be used by the underwriters to make resales of the securities in respect of which this prospectus is being delivered to the public. If underwriters are utilized in the sale of any securities in respect of which this prospectus is being delivered, such securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters at the time of sale. Securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters. If any underwriter or underwriters are utilized in the sale of securities, unless otherwise indicated in the applicable prospectus supplement, the underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters with respect to a sale of such securities will be obligated to purchase all such securities if any are purchased.

      We may grant to the underwriters options to purchase additional securities, to cover over-allotments, if any, at the initial public offering price (with additional underwriting commissions or discounts), as may be set forth in the prospectus supplement relating thereto. If we grant any over-allotment option, the terms of such over-allotment option will be set forth in the prospectus supplement for such securities.

      If a dealer is used in the sale of the securities in respect of which this prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale. Any such dealer may be deemed to be an underwriter, as such term is defined in the Securities Act, of the securities so offered and sold. The name of the dealer and their terms of the transaction will be set forth in the prospectus supplement relating thereto.

      Offers to purchase securities may be solicited directly by us and the sale thereof may be made by us directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act of 1933 with respect to any resale thereof. We may also offer securities through agents in connection with a distribution to our stockholders of rights to purchase such securities. The terms of any such sales will be described in the prospectus supplement relating thereto.

      Subject to the limitations under Rule 415(a)(4)(ii) under the Securities Act, we may offer our equity securities into an existing trading market on the terms described in the applicable prospectus supplement. Underwriters and dealers who may participate in any at-the-market offerings will be described in the prospectus supplement relating thereto.

      Pursuant to any standby underwriting agreement entered into in connection with a subscription rights offering to our stockholders, persons acting as standby underwriters may receive a commitment fee for all securities underlying the subscription rights that the underwriter commits to purchase on a standby basis. Additionally, prior to the expiration date with respect to any subscription rights, any standby underwriters in a subscription rights offering to our stockholders may offer such securities on a when-issued basis, including securities to be acquired through the purchase and exercise of subscription rights, at prices set from time to time by the standby underwriters. After the expiration date with respect to such subscription rights, the underwriters may offer securities of the type underlying the subscription rights, whether acquired pursuant to a standby underwriting agreement, the exercise of the subscription rights or the purchase of such securities in the market, to the public at a price or prices to be determined by the underwriters. The standby underwriters may thus realize profits or losses independent of the underwriting discounts or commissions paid by us. If we do not enter into a standby underwriting arrangement in connection with a subscription rights offering to our stockholders, we may elect to retain a dealer-manager to manage such a subscription rights offering for us. Any such dealer-manager may offer securities of the type underlying the subscription rights acquired or to be acquired pursuant to the purchase and exercise of subscription rights and may thus realize profits or losses independent of any dealer-manager fee paid by us.

      Securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms (“remarketing firms”) acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreement, if any, with us and its compensation will be described in the applicable prospectus supplement. Remarketing firms may be deemed to be underwriters, as that term is defined in the Securities Act of 1933, in connection with the securities remarketed thereby.

      If so indicated in the applicable prospectus supplement, we may authorize agents, dealers or underwriters to solicit offers by certain institutions to purchase securities from us at the public offering price set forth in the applicable prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the applicable prospectus supplement. Such delayed delivery contracts will be subject to only those conditions set forth in the applicable prospectus supplement. A commission indicated in the applicable prospectus supplement will be paid to underwriters and agents soliciting purchases of securities pursuant to delayed delivery contracts accepted by us.

      Agents, underwriters, dealers and remarketing firms may be entitled under relevant agreements with us to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such agents, underwriters, dealers and remarketing firms may be required to make in respect thereof.

      Any underwriter may engage in stabilizing and syndicate covering transactions in accordance with Rule 104 under the Securities Exchange Act of 1934. Rule 104 permits stabilizing bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. The underwriters may over-allot shares of the securities in connection with an offering of securities, thereby creating a short position in the underwriters’ account. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing and syndicate covering transactions may cause the price of the securities to be higher than it would otherwise be in the absence of such transactions. These transactions, if commenced, may be discontinued at any time.

      Unless otherwise specified in the applicable prospectus supplement, each series of securities will be a new issue and will have no established trading market. We may elect to list any series of securities on an exchange but, unless otherwise specified in the applicable prospectus supplement, we shall not be obligated to do so. No assurance can be given as to the liquidity of the trading market for any of the securities.

      Agents, underwriters, dealers and remarketing firms may be customers of, engage in transactions with, or perform services for, us and our subsidiaries in the ordinary course of business.

      The anticipated date of delivery of securities will be set forth in the applicable prospectus supplement relating to each offer.

LEGAL MATTERS

      Unless otherwise specified in the applicable prospectus supplement, the validity of the securities will be passed upon for us by Vinson & Elkins L.L.P., Houston, Texas, and will be passed upon for any agents, dealers or underwriters by counsel named in the applicable prospectus supplement.

EXPERTS

      Our consolidated financial statements and schedule appearing in our Annual Report on Form 10-K/ A for the year ended December 31, 2004, and our management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2004 included therein, have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in its reports thereon (which conclude, among other things, that we did not maintain effective internal control over financial reporting as of December 31, 2004, based on Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, because of the effects of the material weakness described therein), which are incorporated by reference in this prospectus and elsewhere in the registration statement.
