American Airlines began in 1926 with a flight piloted by Charles Lindberg carrying mail from St. Louis, Missouri to Chicago, Illinois. Soon thereafter, founder C.R. Smith was instrumental in bringing the DC-3, a plane that revolutionized aviation, into service. A legacy carrier, American Airlines continued to grow and expand routes over the decades that followed.

In 2013, American Airlines’ AMR Corporation and US Airways Group formed the American Airlines Group. Two years later, American and US Airways began operating as one airline. American Airlines is a member of the oneworld® alliance, which serves more than 1,000 cities in 160 countries.
