With post-security walkway connections across all terminals, navigating SFO lounges is straightforward provided you know where lounges are currently located during ongoing airport construction.

1. Post-Security Terminal Walkways & Airside Map
SFO is organized in a ring shape around central parking structures.
Post-security connecting corridors link every terminal behind TSA security. You can walk continuously between Harvey Milk Terminal 1, Terminal 2, Terminal 3, International Terminal A, and International Terminal G without exiting the secure area.
Walking from International Terminal A to International Terminal G across the terminal ring takes significant time. Allow adequate walking time when visiting distant lounges.
