San Francisco International Airport (SFO) is one of the busiest airports in the United States, managing both domestic flights and international links for Europe, and Latin America. The airport was first opened on May 7, 1927, on 150 acres of land that was certified by the famous local landowner Ogden L.A. Mills, and in connection with it is called Mills Field Airport. His name remained Mills Field until 1931, after which his name was changed to San Francisco Municipal Airport, which was later replaced by the City at the International somewhere around 1955.
The airport serves the cosmopolitan city of San Francisco, Silicon Valley and the wide Gulf region. It is the largest Bay Area airport, and is the second busiest airport in the state of California. As of 2009, San Francisco International Airport is the 10th largest in the United States and the 20th largest airport in the world, in terms of passengers.
There are four terminals within SFO which are Terminal 1, 2, 3 and International Terminal which is very much loved. Three of the terminals are used for domestic flights and bound flights in Canada, while the international terminal is obviously not aimed at international flights. There are seven concerts working on each of these terminals. The Ascension Area A and G are used in an international terminal for handling international flights. Terminal 1 and 3 with B&C and E&F boarding areas respectively handle local bound flights and Canada. Although Terminal 2 with the boarding area D has undergone some renovation work.
SFO Airport recommends an extensive array of facilities and services, including a variety of restaurants, shops, business center, Wi-Fi, disabled facilities and banking services. There are very few specialties available at San Francisco Airport, which are aquarium, aviation library and museum, demonstration room, children's play area. An internal transport system, AirTrain, is used to link all the different parts of the airport. Another train service called Metro Rail service is used to travel between an airport, bay area and city.
