Airport Terminals and Gates

San Francisco’s Airport has four passenger terminals surrounding the ‘Terminal Loop – International Terminal (IT) is the first one when entering the terminal area – followed by the domestic terminals and their concourses, which surround the Domestic Garage area, while International Garages A & G are further south of the international Terminal – at opposite sides of the Terminal loop. Domestic Terminals 1, 2 & 3 also handle pre-TSA clearance flights.

Getting Around: As all terminals are arranged in a circle, the Red-line of the AirTrain (an automated people mover) serves all terminals & the garage, while the Blue line of the AirTrain additionally serves the rental car facility – both lines run a continuous loop taking only minutes between stops (baggage carts have hand brakes and can be taken onto the AirTrain); however, you can also walk to your connecting terminal.
