AmericanConnection was an American flight connection service brand name for the spoke-hub of U.S. mainline carrier American Airlines, under which regional airline operator Chautauqua Airlines operated feeder flights for American Airlines at its Chicago hub. American Airlines also uses affiliated companies ( corporations under common ownership) operating under the American Eagle brand to provide regional service to its other hubs in addition to the AmericanConnection service that was operated by Chautauqua Airlines.
On April 6, 2010, American moved all existing AmericanConnection operations to Chicago-O'Hare as part of its restructuring plan, eliminating service by AmericanConnection at Lambert-St. Louis.
At one time AmericanConnection operated over 180 flights a day to 21 destinations. AmericanConnection was an affiliate member of the Oneworld airline alliance.
