Security Checkpoints

Security checkpoints are located at the entrance to boarding areas. Only ticketed passengers are permitted beyond the checkpoints. In addition to the general lanes, all security checkpoints except F3 offer TSA Pre-Check, Priority Line and Clear lanes. Security checkpoint F3 does not have a TSA Pre-Check lane.

Passengers can connect to certain terminals without exiting and re-entering security. Post-security connectors are available between:

• Harvey Milk Terminal 1, Gates C2 through C11 and Terminal 2, Gates D1 through D18.
• International Terminal, Gates G1 through G14 and Terminal 3, E1 through E13 and Gates F1 through F22.

Please note that arriving international passengers who are connecting to other flights must go through the federal inspection process at their first point of entry into the United States, exit and re-enter security. International flights that have been precleared are not required to undergo the federal inspection process again upon arrival.
