Check SFO Conditions & Security Waits
SFO publishes timestamped General and TSA PreCheck estimates by checkpoint. Check the checkpoint closest to your gate, then current airport alerts and your operating airline.
Checkpoint estimates can change quickly. SFO says all gates are accessible from any checkpoint, but the closest checkpoint usually avoids unnecessary walking.
BEFORE YOU GO
Five checks in the right order
- Confirm your operating airline, terminal and gate letter.
- Open SFO’s wait page and check its displayed update time.
- Compare General and TSA PreCheck only for lanes you can actually use.
- Check SFO travel alerts for AirTrain, BART and construction impacts.
- Confirm the individual flight with the operating airline and check FAA status for airport-wide restrictions.
LOCATION-SPECIFIC GUIDANCE
Checkpoint letters and terminal changes matter
- Checkpoint letters correspond to nearby gate areas, such as Checkpoint B for B gates.
- SFO currently states that all gates are accessible from any checkpoint after screening.
- AirTrain’s Red Line serves terminals and terminal garages; the Blue Line also reaches Long-Term Parking and the Rental Car Center.
- Terminal 3 construction can change check-in paths, especially for United passengers using D, E and F gates.
- FAA status describes broader air-traffic restrictions, not airline-specific crew, gate or maintenance delays.
COMMON QUESTIONS
Avoid common traps
Can I use any SFO checkpoint?
SFO says all gates are accessible from any checkpoint, but verify lane eligibility and allow for the walk to your gate.
Are the displayed waits guaranteed?
No. They are current estimates; check the page timestamp and preserve normal arrival time.
Does FAA status confirm my flight?
No. Confirm the individual flight with its operating airline.
