How to read SFO wait coverage

Live minutes

When the source publishes minute values, treat them as the current snapshot, not a guarantee for your future arrival.

Missing or stale data

If live waits are missing, suspended, or outside the freshness window, use posted hours, airport advisories, and peak-window context instead.

Checkpoint counts

Counts reflect what the official source returns for tracked checkpoints; they may not equal every physical lane or every checkpoint serving your gate.

Planning bullets

How locals actually plan SFO

SFO gives you flexibility after security, which makes line choice powerful.

All terminals are linked post-security, so the fastest published checkpoint is often the right move.

Long terminal walks still matter, especially if you are heading to an international gate.

Use the live board to clear security fast, then budget realistic time for the walk to your gate.

Checkpoint access

Which checkpoint reaches your gate?

SFO says all terminals are connected by both pre- and post-security walkways, so once screened you can walk to any gate.
