The airport covers of land. The airport is an operating base for Southwest Airlines, which operates point-to-point routes with bases instead of a traditional network with hubs. History Early years The city of Oakland looked into the construction of an airport starting in 1925. The announcement of the Dole Air Race for a flight from California to Hawaii provided the incentive to purchase in April 1927 for the airport. The runway was the longest in the world at the time and was built in just 21 days ahead of the Dole race start. The airport was dedicated by Charles Lindbergh on September 17. In its early days, because of its long runway enabling safe takeoff rolls for fuel-heavy aircraft, Oakland was the departing point of several historic flights, including Charles Kingsford Smith's historic US-Australia flight in 1928 and Amelia Earhart's final flight in 1937. Earhart departed from this airport when she made her final, ill-fated voyage, intending to return there after circumnavigating the globe. Boeing Air Transport (a predecessor of United Airlines) began scheduled flights to Oakland in December 1927. It was joined by Trans World Airlines (TWA) in 1932. In 1929 Boeing opened the Boeing School of Aeronautics on the field, which expanded rapidly in 1939 as part of the Civilian Pilot Training Program. Thousands of pilots and mechanics were trained before the facility was changed into the United Air Lines training center in 1945. In 1943 the U.S. Armed Forces temporarily took over Oakland Airport and opened Naval Air Station Oakland. It was transformed into an airlift base for military flights to the Pacific islands, ordering all scheduled services to move to San Francisco International Airport. After the war, airlines slowly returned to Oakland; Western Airlines began flights in 1946, and was followed by American Airlines, TWA, United, Transocean Air Lines and Pacific Southwest Airlines (PSA). Oakland became a larger center for non-scheduled and supplemental air carriers: The four largest such companies were based and headquartered in Oakland: Transocean Air Lines, World Airways, Trans International Airlines and
