San Francisco International Airport (SFO IATA) is the main international airport of the San Francisco Bay Area in California, the United States.


San Francisco International Airport, or commonly called by its IATA identifier, SFO, sits between San Francisco and San Jose, roughly 15 miles south of downtown San Francisco, and 35 miles northwest of San Jose, at the western side of San Francisco Bay. Within California, its passenger traffic is second only to Los Angeles. SFO is the 7th-busiest airport in the USA and 22nd-busiest in the world, with nearly 45 million people arriving and departing from the airport annually. The airport was built in 1927, and adopted what is now the centralized terminal design 30 years later.

The airport adopts the centralized terminal concept, with 4 terminals (3 domestic, 1 international) with 7 concourses in a circle surrounding parking and transportation facilities. Some domestic flights depart from the international terminal, and conversely, some international flights to Canada depart from the domestic terminals.

San Francisco is a major hub for both domestic and international flights to the United States. United Airlines operates a hub out of Terminal 3, while Alaska Airlines operates a hub from both Terminal 2 and the International Terminal, with flights allocated to either terminal at random; check the flight information before you head to the airport for the correct terminal. Though it has a wide range of flights, it's well known for its weather delays.

Arrival procedures[edit]

At the entrance to the International Terminal

The two sets of parallel runways at SFO are spaced too closely together for simultaneous arrivals during periods of low visibility. While in clear weather, both runways in a particular direction can be used, low clouds (a not uncommon weather pattern in the Bay Area) will require that arrivals use only one of the two. Should this happen, air traffic control will delay inbound traffic either in the air or at your departure airport. If you are making connections at SFO or have time-sensitive business there, allow for extra time should your incoming flight be delayed.

International arrivals: All passengers arriving on international flights (except origins with US preclearance) will be processed through immigration. Passengers will then collect their baggage and pass customs. Those with onward flights, international and domestic, will proceed to check-in and security. Be prepared for a 30-40 minute wait. There is no international transit zone. Travellers terminating in San Francisco should follow signs for their desired ground transportation.

Domestic arrivals: Passengers arriving on domestic flights will arrive on the departure level inside security. Those in transit will not need to clear security again unless their next departure leaves from a different terminal that does not have a walkway between them. Travelers terminating in San Francisco exit and may proceed downstairs to baggage claim or ground transportation. The AirTrain and BART is available upstairs.

Departure procedures[edit]

Passengers must check in with their airline at their respective terminal. Once you pass the security checkpoint, you generally cannot go to other concourses (some exceptions under #Get around). This limits your choice of food, drinks, and shopping.

International travelers will not pass exit controls; however, airline staff will verify passport and applicable destination visa validity.

Ground transportation[edit]

Map of the airport

By train[edit]

If you are staying in San Francisco or the East Bay, your most convenient option will likely be BART. The platform is at Parking Garage G. You can get there from any of the terminals using the AirTrain.

If you are going south to San Jose, you can take the Caltrain commuter rail line, but you first need to take the BART to Millbrae, where you can transfer to Caltrain. You can take BART directly to Millbrae from the airport after 8PM on weekdays, and all day on weekends. During other times, you need to take BART to San Bruno, then backtrack on another BART line to Millbrae.

There are no trains from the airport to Marin County, across the Golden Gate Bridge from San Francisco. To get there you'll need to take the Airporter bus (see below), or transfer to a ferry or bus in San Francisco.

By bus[edit]

SamTrans provides bus service throughout San Mateo County and limited service to and from San Francisco. There are bus stops at the International Terminal, Terminal 2, and Terminal 3. Routes KX, 292, 397 and 398 stop directly at the Airport terminals. Routes 140, 292 and 397 stop at the Rental Car Center.

SamTrans bus tokens (valid for local fares) are available for purchase at a discount in bags of ten at several Airport Information Kiosks:

  • International Terminal -- Arrival Level (Outside Exit A & Exit G)
  • International Terminal -- Departure Level (Near Ticket Aisle#1 outside BART station entrance)
  • Domestic Terminals 1 and 3 (Baggage Claim Area)

The Marin Airporter offers service every half hour to and from Marin County, operating from 5AM to midnight. The Airport Express offers service every hour to and from Sonoma County, with similar hours of operation. The Santa Cruz Airport Flyer provides service to SJC, Scotts Valley, and Santa Cruz.

The Monterey Airbus provides service to SJC and Monterey.

By car[edit]

  • The airport is accessible via Highway 101 and the surface street McDonnell Road. Freeway traffic is often congested, plan accordingly.
  • The Rental Car Center is connected to the airport terminals via the AirTrain.

Get around[edit]

Pre-security all terminals are reachable on foot. The Rental Car Center however is not, and requires the AirTrain.

The AirTrain rail system can get you around the airport. The AirTrain runs 24 hours a day and is free.

  • The Red Line circulates the terminals plus the International Garages near Concourses A & G, and the BART train station at the garage near Concourse G.
  • The Blue Line stops at all of the Red Line stations, plus West Field Road and the Rental Car Center. You can also walk between terminals.

If you're parking at the Long-term Parking Lot, you need to use a shuttle to get to the terminals. The shuttle picks up from the departure level of each terminal, runs 24 hours a day (every 5 minutes from 4AM to midnight, 15 minutes all other times), and is free.

After security (airside), Terminal 3 and International Terminal G are connected by a walkway to facilitate Star Alliance connections, and Terminal 1 and Terminal 2 are similarly connected (but be careful you don't accidentally walk out of security!). Otherwise you cannot move between terminals after security. In some cases you can't even move between concourses within the same terminal while inside security.

The surrounding communities also have plenty of accommodations. San Bruno directly to the west, Millbrae and Burlingame to the south along US 101, or South San Francisco and Brisbane to the north along US 101 have plenty of chain hotels to choose from. Most of these hotels run shuttles to the airport, which stop at the designated area on the Departures level in front of each terminal.
