San Francisco's Airport has four passenger terminals - International Terminal (IT), and Domestic Terminals T1, T2, & T3 - arranged in a circle around the domestic garages. To the South of the garage complex is the large International Terminal with Boarding Areas A & G. To the North of the garage complex, at center, is T2 with Boarding Area D; southwest of T2 is T3 with Boarding Areas E & F; southeast of T2 is Terminal 1 with Boarding Areas B & C. Domestic Terminals 1, 2 & 3 also handle pre-TSA clearance flights (originating from Airports offering U.S. preclearance).
- Information booths are available in all terminals, at pre- & post-security areas with optional language assistance.
- Water bottle refill stations are at post-security of all terminals' boarding areas near their gates: A1, G93, B23, C43, D51, D58, E68, F80-90.
- United uses T3 exclusively, Virgin America & American share T2, Frontier, Delta & Southwest share T1; while all international airlines and currently U.S. airlines Alaska, Jet Blue, Hawaiian & Sun Country use the International Terminal IT - except Virgin America, which uses IT for arrivals from Mexico (A gates), and T2 for all departures to Mexico (D gates), while its domestic flights depart/arrive at T2's D gates (but check with Virgin America first as this may change).
Getting around: (As all terminals are arranged in a circle, walking around the entire terminal loop would take 25 minutes.)
The Red-line of the AirTrain (an automated people mover) serves all terminals & the garage, while the Blue line 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.
Arriving international passengers not transferring to another flight go through Customs clearance, pick up their bags at the baggage claim, and exit through doors marked 'San Francisco' into the international arrivals meeting area, with ground transport options.
Domestic passengers transferring from either T1 or T2 to the International Terminal must exit their terminal, then walk or take the AirTrain to the International Terminal, where they need to go through security checkpoint before proceeding to their departure gate. If they have not yet checked in for their connecting flight, they need first to stop by at their airline counter in the Main Hall before proceeding to the International Terminal.
Domestic passengers transferring from T3 to the International Terminal may transfer via a connector walkway (located post-security near gate 75) to the International Terminal's Boarding Area G arriving at post-security near gate G92. If they have not yet checked in for their connecting flight, they need to stop by at their airline counter in the Main Hall and then take either the AirTrain or walk to the International Terminal, where they need to go through security check before proceeding to their connecting gate.
International passengers transferring to Domestic Terminals: There is no secure transit area in this case. To connect to any of the domestic terminals, take the AirTrain’s red line at either station A or G below the Main Hall. To get to Terminal 3, you can also use the short connector between Boarding Area G and Terminal 3 and its F gates.
International Arrivals Procedure: Unless you have gone through US customs clearance at participating airports, you need to go through passport check or use APC or MPC kiosks*, retrieve checked bags, go through customs clearance and - if transferring to another flight - re-check-in bag: Onward passengers will exit Arrivals Hall through dedicated doors indicating 'Connecting Flights', where they will re-check in bags at the baggage desk directly outside of the exit. If no agent is available there, or bags are not tagged to its final destination, visit your airline's ticket counter first.
Security Check Lines: A frequent flyer remarked: "It is fast going through premium class (minutes), but through the regular line, arrive 2-3 hours minimum before time. I have watched airlines refuse boarding to ticketed passengers if they did not meet the international check-in time requirement. Needless to say the passengers were not happy..."
* Automated Passport Control kioks (APCs): 40 BorderXpress APC kiosks have been installed - expediting the US Customs (CBP) process considerably. They collect passengers' facial & fingerprint biometrics against their passports - approved by US Customs and Border Protection (CBP). Self-service APCs may be used by US & Canadian passport holders, by US permanent residents & by international travelers from Visa-waiver countries. The process takes about 90 seconds.
* MPC Mobil Passport Control is now available for US citizens holding a valid US passport, and to Canadian citizens with both a valid Canadian passport and B1 or B2 visa status. MPCs help expedite arrival at USA by submitting passport info & customs declaration forms from their mobile devices prior to arrival. Android and iPhone users may download the MPC app for free from the Google Play Store and Apple App Store. From there, profiles may be set up for the passenger and other members of the family. Upon submission, an encrypted CBP receipt with a barcode will appear on the device.
