Founded in 1931 as American Airways, American Airlines (AA) is the world's largest airline when measured by revenue and fleet size. A founding member of the Oneworld alliance, AA operates a primary hub at Dallas Fort Worth International Airport (DFW) and has eight secondary hubs at airports across the United States. The airline flies to about 345 destinations in North America, the Caribbean, South America, Asia and Europe. It has codeshare agreements with 15 other carriers, as well as joint ventures with British Airways, Japan Airlines, Iberia, Finnair and Qantas on certain routes. Its fleet consists of 963 aircraft.
American Airlines allows passengers to choose their seats in most cases, but there are times when the seats will be assigned at check-in. The carrier may withhold some seats until the day of departure to best accommodate passengers. Economy Class passengers will enjoy a seat pitch of 30-32 inches, while Business and First Class passengers can relax comfortably with 38-40 inches of legroom or a lie-flat seat.
