AMR in the News From Chicago Business Journal American Wants New Nonstops to Sao Paulo American is in the final stages of petitioning the U.S. Department of Transportation to fly between Chicago’s O’Hare and Sao Paulo, Brazil. If the carrier is successful, the new route would be the only South American nonstop route American would operate from Chicago. American’s Miami and DFW hubs have a number of nonstop flights to various South American destinations. If the DOT grants American’s request, service would begin in October 2014. Chicago Mayor Rahm Emanuel said “this proposed service… would not only provide significant consumer benefits to the traveling public in the Chicago area, but also generate consumer benefits for passengers in numerous cities and regions in the United States.” American also is petitioning the DOT to begin service in November of this year from Los Angeles to Sao Paulo.
