Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at SFO handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Boarding Area B only, Gates B1–B27 (26 gates, 6 capable of international processing). Fully renovated and reopened April 2023 — world's first airport terminal named after an LGBTQ+ civil-rights leader. Airlines: Alaska Airlines, American Airlines, Delta Air Lines, Hawaiian Airlines, JetBlue Airways, Porter Airlines, Sun Country Airlines, WestJet. Lounges: Alaska Lounge, Admirals Club. Connects airside to T2 to the south.
Two concourses: Boarding Area C (Gates C2–C11) and Boarding Area D (Gates D1–D12, D14–D18). Airlines: Air Canada, Breeze Airways. Widely regarded as one of the best-designed terminals in the US. AirTrain station temporarily renamed 'Terminals 2 and 3' as of Nov 2025 while T3's own station is closed for renovation. Connects airside to T1 (north) and T3 (south).
Two concourses: Boarding Area E (Gates E1–E13) and Boarding Area F (Gates F1–F22) — 36 gates total. United Airlines domestic hub; two United Club lounges. Currently under a major $2.9 billion T3 West Modernization project through approximately 2027. Own AirTrain station closed November 4, 2025; passengers use the T2 AirTrain station instead. Connects airside to T2 (north) and International Terminal G (south).
Boarding Area A (Gates A1–A15, southern side): Aer Lingus, Aeromexico, Air France, Air India, Air Premia, Avianca, British Airways, Cathay Pacific, China Airlines, China Eastern, China Southern, Copa Airlines, Emirates, EVA Air, French Bee, Frontier Airlines, Iberia, ITA Airways, Japan Airlines, KLM, Korean Air, Philippine Airlines, Qantas, Qatar Airways, Starlux, TAP Air Portugal, Turkish Airlines, Vietnam Airlines, Virgin Atlantic, Zipair. Boarding Area G (Gates G1–G14, northern side): Air China, Air New Zealand, ANA, Asiana Airlines, Fiji Airways, Lufthansa, SAS, Singapore Airlines, Swiss International Air Lines, United Airlines (international flights). ITB is the largest terminal; A and G are on opposite ends — airside walk between them requires transiting T1+T2+T3 (~20–25 min). Fastest A-to-G connection is to exit security and take the free AirTrain.

Free AirTrain automated people mover runs every 4 minutes, 24/7. Red Line runs clockwise stopping at all terminals, terminal garages, BART station, and Grand Hyatt. Blue Line runs counterclockwise, also serving the Rental Car Center and Long-Term Parking. Full loop takes approximately 9–10 minutes. Since June 17, 2024, SFO also completed a full ring of post-security airside connectors: passengers can walk T1 — T2 — T3 — ITB-G — ITB-A — T1 without exiting the sterile area or re-clearing security. Note: T3's own AirTrain station is closed (as of November 4, 2025, through approximately 2027) for the T3 West renovation; the T2 station now serves both T2 and T3.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at SFO — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
Use the airside walkways for quick terminal-to-terminal connections without re-clearing security — all terminals have been linked post-security since June 2024. The one exception: to move between International Terminal Boarding Area A and Boarding Area G without a 20–25 minute walk through three domestic terminals, exit security and take the free AirTrain (every 4 min) for a roughly 5-minute ride instead.
A few habits that prevent last-minute sprints:
Experienced travellers at SFO use a short checklist every time:
