In 2014, it was the seventh busiest in the United States and the twenty-first busiest airport in the world by passenger count. It is the fifth largest hub for United Airlines, functions as United Airlines’ primary transpacific gateway – and is one of United’s more than 330 destinations worldwide.BOOK NOW
AirTrain is the airport’s people-mover system. Fully automated and free of charge, it connects all four terminals, the two international terminal garages, the BART station, and the airport’s Rental Car Center.
The San Francisco International Airport (SFO) BART station, located in Parking Garage G of the International Terminal, is the only direct rail link between the airport, the city of San Francisco, and the general Bay Area. The SFO station is served by the Pittsburg/Bay Point – SFO/Millbrae line.
BART is SFO’s connection to Caltrain at the Millbrae Station, which requires a transfer at the San Bruno station during most of BART’s weekday operating hours; direct service between SFO and Millbrae is available on weekday evenings, weekends, and holidays. Caltrain used to offer a free shuttle to SFO airport from the Millbrae station, but it was replaced by BART service when the SFO extension was completed.
The San Francisco Municipal Railway, San Francisco’s transit agency, does not provide service to the airport. However, SamTrans, San Mateo County’s transit agency, does, with five lines, 140, 292, 397, 398, and KX, connecting the Airport with Downtown San Francisco, the Peninsula, and as far south as Palo Alto. In particular:
- Route 140 provides local service from the Rental Car Center (accessible via AirTrain) to San Bruno, South San Francisco, and Pacifica, stopping at San Bruno Caltrain, San Bruno BART, and Skyline College for connections within San Mateo County and beyond.
- Route 292 serves the airport daily between San Francisco and Hillsdale Mall via Bayshore Boulevard and Downtown San Mateo.
- Route KX provides express service to the airport from Redwood City (northbound) during the morning commute and from San Francisco (southbound) during the afternoon and evening commute.
- Route 398 serves the airport when Route KX does not operate, and it runs between San Bruno BART and Redwood City Caltrain. This route operates daily except during certain times at peak periods on weekdays.
- Route 397 operates to the airport during the overnight hours as a part of the Bay Area’s “All Nighter” service. This service mirrors that of Route 292 north of the airport (with an additional stop at Civic Center BART/Muni Metro Station), with service continuing south via Millbrae BART/Caltrain Station and El Camino Real to and from Palo Alto Caltrain.
Samtrans can be accessed on the arrivals/baggage claim level of the domestic terminals and in courtyard A or G in the International Terminal.
Numerous door-to-door “shared ride” van and hotel courtesy shuttles stop at the center transportation island on the departure level, while airporter and limousine are on the arrivals/baggage claim level of the airport. Charter services are also available in the courtyards.
The airport is located on U.S. Route 101, 13 miles (21 km) south of downtown San Francisco. It is near the US 101 interchange with Interstate 380, a short freeway that connects US 101 with Interstate 280.
The airport provides both short-term and long-term parking facilities.
Short term parking is located in the central terminal area and two international terminal garages. Long term parking is located on South Airport Blvd. and San Bruno Ave. and are served by shuttle buses.
Passengers can also park long-term at a select number of BART stations that have parking lots, with a permit purchased online in advance.
Taxis depart from designated taxi zones located at the roadway center islands, on the Arrivals/Baggage Claim Level of all terminals.
Ride share services (or transportation network companies) such as Lyft and Uber are available via their respective mobile app and can be picked up at the curbside of the each terminal’s departure (not arrival) level.
