San Francisco Airport Shuttles, Taxis and Trains

San Francisco International Airport is served directly by train, taxi, and public bus services.

Airport Train Services


The train's Red Line is a short, circular route with stops that serve all the terminals, their associated short-term (and daily) parking garages, and the BART rail station. The Blue Line operates on a longer circular route, linking a rental car center stop with the stops for the terminals, garages, and BART rail station. Services run 24 hours a day.


Bay Area Rapid Transit (BART) provides a metro rail service within the San Francisco urban area. It has a station at the airport. AirTrain links to the BART station at the garage G / BART station stop. The BART station is located on the G gate's side of the International Terminal on Level 3, which is the departures / ticketing level.

BART services run for most of the day, with a down time in the hours of the early morning. Some services go north to San Francisco, traveling though the center of the city and terminating on the other side of the Bay in Dublin / Pleasanton. Many other services interconnect with this line, allowing passengers to travel to and from a large number of places in the Bay Area. Other services go north to Millbrae Intermodal Station, where they connect with CalTrain. Many BART stations offer parking facilities.


BART trains from the airport connect with CalTrain services at Millbrae Intermodal Station. CalTrain operates train services between San Francisco and San Jose, stopping at many other stations along the way, including Palo Alto and Stanford.
