Postwar developments

After World War II, American launched an international subsidiary, American Overseas Airlines, to serve Europe; AOA was sold to Pan Am in 1950. AA launched another subsidiary, Líneas Aéreas Americanas de Mexico S.A., to fly to Mexico and built several airports there. American Airlines provided advertising and free usage of its aircraft in the 1951 film Three Guys Named Mike.[10]
American Airlines introduced the first transcontinental jet service using Boeing 707s on January 25, 1959. With its Astrojets, as it dubbed the jet fleet, American shifted to nonstop coast-to-coast flights, although it maintained feeder connections to cities along its old route using smaller Convair 990s and Lockheed Electras. American invested $440 million in jet aircraft up to 1962, launched the first electronic booking system (Sabre) with IBM, and built an upgraded terminal at Idlewild (now JFK) Airport in New York City which became the airline's largest base.[11]
From 1971-1978 Beverly Lynn Burns worked as a stewardess for AA. She went on to become the first woman Boeing 747 airline captain.[citation needed]
In 1975 American Airlines was headquartered at 633 Third Avenue in the Murray Hill area of Midtown Manhattan, New York City.
