American Overseas Airlines (AOA) was an airline that operated between the United States and Europe between 1945 and 1950. It was headquartered in Midtown Manhattan, New York City.2

The story

American Export Airlines (AEA), commonly known as Am Ex, was founded in April 1937 as a wholly owned subsidiary of the shipping company American Export Lines. Transatlantic surveys were done with a Consolidated PBY-4 flying boat and in 1939 AEA placed an order for three Vought-Sikorsky VS-44 flying boats, dubbed 'Flying Aces', named after the parent company's Four Aces. That same year, AEA made an application to the U.S. Civil Aeronautics Board (CAB) for routes across the Atlantic from the United States to the United Kingdom, France, and Portugal. On July 15, 1940, in spite of strong protests by Juan Trippe, the president of Pan American Airways (PAA), President Franklin D. Roosevelt gave his approval to AEA for a seven-year temporary certificate to serve Lisbon (Portugal) from New York City-La Guardia Flying Boat base. Later, services were also flown to Foynes (Ireland). These services ended in 1944 when AEA started operations on behalf of the U.S. Air Transport Command (ATC), using Douglas C-54 Skymasters mainly between the US and military bases in North Africa.

AEA could not begin its New York City (USA) – Foynes (Ireland) flying boat service before June 1942, due in part to vigorous objections from PAA.

Postwar operations

In 1945, AEA was awarded transatlantic rights, which covered destinations in Northern Europe with the requirement that the shipping company (American Export Lines) divest itself of control and turn the control over to another carrier, so that an airline was not controlled by a surface carrier. Consequently, enough stock was sold to American Airlines to give them control, but the chairman of the board of AEA, J. E. Slater, remained. American Airlines was interested in acquiring AEA since it wanted to break into the overseas market, dominated at that time by PAA. The US CAB approved the acquisition of AEA by American Airlines on July 5, 1945. The La Guardia – Botwood – Shannon route was initially operated by Vought-Sikorsky flying boats using the Marine Air Terminal at LaGuardia Airport. By 1948 the airline also served Prestwick, Amsterdam, Frankfurt, Berlin, Keflavik, Oslo, Copenhagen, Stockholm and Helsinki.

The AEA name was retained until November 1945 when AEA was renamed to American Overseas Airlines. The entity started operations with six C-54s at the end of AEA's ATC contract.

AOA launched international landplane flights on October 24, 1945, operating a Douglas DC-4, Flagship New England (N90904), on the route New York City to London via Boston, Gander (Newfoundland) and Shannon (Ireland).

The reliable but unpressurised DC-4s were replaced on the Atlantic routes by Lockheed L-049 Constellations from 23 June 1946. From summer 1949 the Constellations were supplemented and then largely replaced by Boeing 377 Stratocruisers, the first AOA service by the type being on 17 August that year to London Heathrow Airport.

AOA was acquired by PAA but on May 17, 1950, the US CAB ruled against this merger. President Harry S. Truman, however, overturned the CAB decision, and AOA was merged into what would become Pan American's Atlantic Division on September 25, 1950. This unit ultimately became part of Delta Air Lines, following Pan Am's bankruptcy in 1991.
