Shortly after the Second World War, the airline established two subsidiaries: American Overseas Airlines and Líneas Aéreas Americanas de Mexico S.A..

In the eighties and nineties, AA gained a lot of new airport on American soil. In 1990, the airline bought 445 million dollar worth of shares from TWA to be able to operate from London Heathrow. In 2001, Trans World was completely taken over by American Airlines. This caused a dispute between the business and the TWA-pilots because they were scheduled to start all at the bottom. In the aftermath of the TWA-merger the 11 September attacks took place in which two aircraft of American were involved. This unfortunate happening caused huge losses. Since the company have managed to expand its network in Asia, which proves out to be profitable.
