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 680 acres (280 ha) in April 1927 for the airport. The 7,020-foot-long (2,140 m) 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: some of the largest such companies were based and headquartered in Oakland including Transocean Air Lines, World Airways, Trans International Airlines, Universal Airlines and Saturn Airways. Other large supplemental carriers, such as United States Overseas Airlines, had operational bases in Oakland. Oakland became one of the largest overhaul and maintenance operations in the country when Aircraft Engine and Maintenance Company (AEMCO) processed thousands of aircraft.

The airport's first Jet Age terminal (now Terminal 1) was designed by John Carl Warnecke & Associates and opened in 1962, part of a $20 million expansion on bay fill that included the 10,000-foot (3048 m) runway 11/29 (now 12/30). The May 1963 OAG showed 15 airline flights arriving in Oakland each day, including nine from San Francisco; in June 1963, TWA flew Oakland's first scheduled jet, a Convair 880, to Chicago. American Airlines scheduled service from Oakland to Phoenix and then into Dallas using the Boeing 720 aircraft. Pacific Southwest Airlines (PSA) provided several flights within California from OAK using Boeing 727 and DC-9 aircraft. United Airlines introduced non-stop service to Chicago and on the San Francisco-Oakland-Los Angeles route using the Boeing 727.

During the Vietnam War, World Airways shuttled thousands of military passengers through Oakland to their bases in Southeast Asia, and an international arrivals facility was built, allowing the airport to handle international flights for the first time. World Airways had broken ground on the World Air Center at Oakland San Francisco Bay Airport. The maintenance hangar could store four Boeing 747s. It opened in May 1973. During its operation, World Airways provided contract maintenance services for 14 airlines in the facility. By 1988, World Airways vacated the Oakland maintenance base and moved its headquarters to Washington Dulles. That same year, United Airlines assumed the lease on the maintenance base.

After the war, Oakland's traffic slumped, but airline deregulation prompted several low-fare carriers to begin flights. This increase prompted the airport to build a $16.3 million second terminal, the Lionel J. Wilson Terminal 2, with seven gates for PSA and AirCal service. In the mid-1980s, People Express Airlines provided scheduled Boeing 747 transcontinental flights from OAK to Newark. SFO Helicopter Airlines served scheduled passenger flights between SFO and the Oakland Convention Center from OAK for many years until 1985. In 1987, British Airways and Air France Concorde visited Oakland to provide supersonic two-hour flights to the Pacific halfway to Hawaii and back to Oakland. Additionally, Concorde returned for a special around-the-world trip covering 38,215 miles over a three-week tour in March 1989.

FedEx Express opened an air cargo base at OAK in 1988, which is now one of the busiest air freight terminals in the United States. In the 1990s, Southwest Airlines opened a crew base in Oakland, and expanded its flights to become the airport's dominant passenger carrier. The airport has international arrival facilities, including U.S. Customs and Border Protection office.
