San Francisco International Airport (SFO) sits on the bay about 13 miles south of downtown San Francisco, and it is the primary gateway to the Bay Area for both domestic and international travelers.
Four Terminals, Linked Airside
SFO has four terminals, numbered 1, 2, and 3 plus the International Terminal, all connected airside so you never have to exit security to change terminals. The BART station sits at the International Terminal, a five-minute walk from Terminal 3 and about ten minutes from Terminal 1, with a free AirTrain shuttle covering the rest.
BART Beats Driving Into the City
BART runs directly from SFO into downtown San Francisco in about 30 minutes, a far more predictable trip than a taxi or rideshare during Bay Area traffic, especially through the 101 corridor.
SFO vs. Oakland and San Jose
Oakland International Airport (OAK) and San Jose Mineta International (SJC) both serve the wider Bay Area and are worth checking too, particularly for Southwest and budget carrier routes that skip SFO.
