Where are you

Before you go

Connect without reclearing TSA

Since June 2024 a sterile walkway links A–T1–T2–T3–G. If you are already through security, walk — don’t ride AirTrain (that dumps you landside).

International arrivals

Everyone on an international arrival clears CBP, then re-clears security for a domestic connection. Budget extra time even with Global Entry.

When to arrive

Domestic: 2 hours. International: 3 hours. Summer mornings often bring marine layer; United and Alaska banks bunch at T3 and T1.

Wi-Fi and charging

Join “#SFO FREE WIFI”. Outlets are at most gates; yoga rooms and Kids’ Spots are post-security in T1, T2, and T3.

Terminals move. Confirm your boarding pass, then treat this as the map. Live flight boards: flysfo.com.
