Official SFO terminal map
Check the official SFO airlines listing to see which concourse your airline generally arrives/departs from.

Gate numbers at SFO now include both the concourse letter and the gate number, starting over at 1 for each concourse. Prior to Oct 16, 2019 gates were simply numbered 1-102 starting from 1 in the A concourse through 102 in the G concourse.



SFO has 2 main airside zones:

1. International Terminal A, Gates A1-A15 and Terminal 1 (Harvey Milk), Concourse B, Gates B1-B27

[Note that there is a short airside corridor between the A and B Concourses. You can enter security from A and go to B gates, and vice versa. The AirTrain station at Terminal 1-B is temporarily closed as of 9-22-21.]

It's possible to walk between gates in a single zone, but going from one zone to another requires clearing security. Several FTers have reported resistance from BP checkers and TSA agents when you try to enter a concourse that is not connected airside to your departure gate. They are mistaken; you can use a same day boarding pass departing SFO at any of the security checkpoints. Press the issue (politely), and you'll get in.

The landside connector between B and C is currently closed due to construction. To go between these two terminals you either need to go upstairs and take the AirTrain, or go down into the parking garage where you can walk freely (on well-marked pedestrian crosswalks) between terminals as well (pictures for walking in the garage can be found in post 512)

If you're arriving from an international destination, unless it's one of the pre-clearance airports, you'll have to clear Customs and Immigration at SFO and then need a departing boarding pass to clear security. SFO has the typical baggage re-check counters right after Customs for connecting passengers. They are usually open, but if closed, you'll need to lug your luggage to the regular domestic check-in counter of your connecting airline.

There's an AirTrain that runs between terminals (including the two parking garages connected to either side of the International Terminal) and the rental car center. AirTrain now has a stop at the long term parking lot. There is one on-airport hotel, a Grand Hyatt, accessible via the AirTrain. Personally, if forum regulars rob_flies_ua and dhuey need to connect between secure zones with only carry-ons, they just walk between terminals instead of waiting for the train. Returnoftheyeti and makfan will walk from BART to all terminals as well.

BART is the local regional commuter rail. The BART station is located on the north side of the airport, adjacent to International Terminal G. You can exit the paid area in two locations. One is by going up an escalator in the middle of the station and then connecting to the air train. You can also walk to the end of the station. Upon exiting you will be in the International terminal, near the chapel. A one-way ticket from SFO to downtown is $9.65.

Outside of the secure zone, but adjacent to International Terminal G is the SFO Museum

Renovation of Boarding Area C will include a connector to T1-B and is expected to be completed by 2024, following which the entire airport will be connected airside (however going from A to G would require passing through B, C, D, E and F).

AirTrain Map:


As the map shows, Red Line runs clockwise; Blue Line runs counterclockwise. The mistake to avoid is getting on the Blue Line and heading off to the rental car center and long term parking lot when you were only trying to go from one terminal to another (e.g., don't take Blue when you want to go from International-G to Terminal 1). CAUTION: recently when arriving in the late evening, the red line has been closed, and only the blue line is operating but in the opposite direction from the arrows show. Keep an eye out for "sandwich board" signs on the platform, and pay attention to the overhead video screens by the boarding doors for accurate real-time directional info.
