American Airlines, the largest carrier in the world, has been known for its strategic hub-to-hub routes that channel significant domestic and international traffic. By examining flight data from Cirium’s online database, one can discern which airports serve as crucial hubs for American Airlines. These connecting airports not only handle a substantial share of domestic travel but also link passengers to hubs with international departures.
The Points Guy highlights American Airlines' beginnings with a 1926 flight from St. Louis to Chicago, where Charles Lindbergh, chief pilot of Robertson Aircraft Corporation, carried mail on what was then a typical flight. The airline later became the first to fly the Douglas DC-3 in passenger service between New York and Chicago in 1936.
Among the most frequent routes is Dallas/Fort Worth International Airport (DFW) to Los Angeles International Airport (LAX), boasting multiple daily round-trip flights with both widebody and narrowbody aircraft. "Flagship Lounges at both of these major airports have premium services for frequent travelers on these routes," providing added comfort.
