The airport's history
San Francisco International Airport (SFO) has a rich history that dates back to the late 1920s. The airport, located in San Mateo County, California, has undergone numerous expansions, demolitions, and reconstructions to become one of the busiest airports in the world.
The City of San Francisco first leased 150 acres of land from the Mills Estate in 1927 for a temporary and experimental airport project. The site, known as Mills Field, was officially dedicated as the Mills Field Municipal Airport of San Francisco in May 1927. In 1930, the city leaders decided to purchase an additional 1,112 acres from the Mills Estate, expanding the airport site. The airport's name was officially changed to San Francisco Airport in 1931, and it was placed under the management of the City's Public Utilities Commission.
In the early years of the airport, carriers such as Western Air Express, Maddux Air Lines, and Century Pacific Lines operated from the airport. United Airlines, which joined in 1934, quickly became the key carrier at the airport, offering services to Los Angeles and New York with Douglas DC-3 aircraft. By 1936, the airport had three runways and a seaplane harbour under construction. During World War II, the airport served as a Coast Guard base and Army Air Corps training and staging base, known as the Naval Auxiliary Air Facility Mills Field.
After World War II, the airport was renamed San Francisco International Airport to reflect the expansion of overseas service. The airport underwent significant expansion, with a new terminal building, a new control tower, and extended runways. In 1947, the airport code "SFO" was introduced, and the addition of international carriers such as British Commonwealth Pacific Airlines and Philippine Airlines contributed to its growing international presence. By 1952, SFO had reached two million annual passengers, highlighting the need for a new terminal, which was dedicated in 1954 as the Central Terminal.
In the late 1950s, SFO became a profitable operation and continued to grow. The first Hilton Airport Hotel opened at the airport in 1962, and in 1971, the groundbreaking ceremony for the North Terminal (now Terminal 3) was held. Today, SFO is the primary international airport serving the San Francisco Bay Area and is a major hub for airlines such as United and Alaska Airlines. The airport has continued to develop its facilities, including the addition of the International Terminal in 2000, which is the largest international terminal in North America.
