San Francisco International Airport - SFO

San Francisco, United States of America (US)

Getting around the airport

Four terminals, seven concourses, AirTrain

San Francisco International Airport lies 21km south of the city. It has four terminals and seven concourses, laid out in a star shape. The concourses are set up in alphabetical order, anti-clockwise, so be sure to travel in the right direction to your terminal to avoid losing time.

Terminals 1, 2 and 3 serve domestic flights while the huge International Terminal serves both international and domestic flights:

  • Terminal 1: Concourses and Gates B and C
  • Terminal 2: Concourse and Gates D
  • Terminal 3: Concourses and Gates E and F
  • International Terminal: Concourses and Gates A and G. These gates are housed in separate terminal buildings, joined by the International Terminal Main Hall. You'll find the BART train station here, too, as well as a medical centre and a good selection of eating options.
  • There are some connections between the terminals:
    • Terminal 3 Boarding Area F is connected to International Terminal Boarding Area G behind security
    • Terminal 1 Boarding Area C is connected to Terminal 2

Travelling between terminals

It's a large airport, and, while you can walk to all terminals, the free, automatic AirTrain shuttle train will shorten your journey considerably. It runs every 2.5 minutes and covers a 10km loop:

  • The Red Line goes clockwise from Concourses G to A (a nine-minute journey)
  • The Blue Line goes anti-clockwise from Concourses A to G and then travels further to the Rental Car Center (a 19-minute journey)

Stop at the 'Garage G/BART Station' stop to take the BART train into the city.

Getting into San Francisco

BART train is a good option

The airport is well connected by public transport, and the train is the easiest, cheapest route into the city. 

Train

The Bay Area Rapid Transit (BART) rapid rail takes you to San Francisco, San Mateo County and the East Bay. Trains leave every 15-20 minutes from: Mon-Fri 04:09-23:54, Sat 06:07-23:54, Sun 08:07-23:54. 
Journey time is 30 minutes to central stations like Powell Street (for Union Square) and Civic Center.

Cost: USD 9.65 one-way (children under four travel free), USD 19.30 round-trip 
Buying tickets:
Automated machines when you get off the AirTrain or online before you travel. The machines take cash and credit cards.
Location: BART Station, International Terminal, level 3, Boarding Area G side

If you're heading to Silicon Valley, take the Caltrain suburban rail service to Palo Alto or San Jose stations. First, take BART one station south to Millbrae station (changing at San Bruno during the week) and then transfer to Caltrain. 

Cost: USD 3.75 one-way (1 Zone), USD 2.25 for every zone upgrade 
Buying tickets: Buy your BART ticket in the airport, and then your Caltrain ticket at Millbrae

Note: Since Jan 2018, you have to pay 50 cent extra for paper tickets. You can get a 'Clipper Card' to avoid this.

This is the cheapest route to the city. SamTrans bus routes KX, 292, 397 and 398 connect the airport to San Mateo County, San Francisco and Palo Alto (1hr 15mins). The KX route is the quickest option for downtown, but doesn't accept passengers with luggage.

Taxi

A taxi journey takes around 26 minutes, depending on traffic, and can be pretty pricey.

Location: Ranks outside every terminal, arrivals level

Ride share

In typical, early-adopter San Francisco style, it's permitted to use the apps Lyft, Uber and Sidecar to make the journey in a local's car for less than a taxi.

Location: Pick up and drop off are at departures level outside the terminals
