SFO TSA wait times at San Francisco International

This page is currently backed by 6 live SFO checkpoint readings, so the terminal and checkpoint spread matters more than a single airport-wide average.

SFO's security page is server-rendered with the live wait-time table already in the HTML, so the collector can scrape it directly without a hidden API.

The table includes a freshness stamp. That lets us treat the data as live airport output rather than a planning estimate.

The collector labels each checkpoint with its terminal area so travelers can tell at a glance whether a time is for International Terminal A, Harvey Milk Terminal 1, Terminal 2, Terminal 3, or International Terminal G.

Checkpoint A serves the International Terminal A side.

Checkpoint B and B-Mezzanine serve the Harvey Milk Terminal 1 side and can show different wait patterns.

Checkpoint D serves Terminal 2.

Checkpoint F serves Terminal 3.

Checkpoint G serves the International Terminal G side.

Because SFO connects all gates after security, passengers can choose a faster checkpoint and walk airside to their gate.

Use the checkpoint closest to your gate area when waits are similar, but do not assume you must screen there if another checkpoint is materially shorter.

TSA PreCheck and CLEAR travelers have flexibility because SFO lists both services across all checkpoints.

SFO explicitly allows passengers with a same-day boarding pass to enter through any checkpoint and walk airside to all gates.

SFO publishes live wait times for six checkpoints: A, B, B-Mezzanine, D, F, and G.

All SFO checkpoints list TSA PreCheck, Priority Line, and CLEAR lanes, so the shortest line can be a real option even outside your closest terminal.
