San Francisco delays
SFO · KSFO · San Francisco International Airport
San Francisco is under a ground delay program. Arrivals have been metered since 22:00 ET because of runway construction, and the FAA expects to lift it at 01:59 ET Mon.
Average delay is running 34m, with the worst slot at 1h 22m. That is 3h 51m from now, if it holds — end times move. Flights are still departing — they're just paced, so expect a new departure time rather than a cancellation. Tight connections are the risk.

About San Francisco delays
- Is San Francisco delayed right now?
- The status at the top of this page is the FAA's, refreshed every minute — it says whether SFO has a ground stop, a ground delay program, or a runway or traffic restriction open, when it started, and when the FAA expects it to end. An advisory describes the airport, not your flight: it tells you the odds, not the outcome.
- Does an FAA advisory at SFO mean my flight is cancelled?
- Rarely. A ground stop holds inbound aircraft at their origin airports and usually lifts within an hour or two; a ground delay program paces arrivals so your departure time moves rather than disappears. Cancellations are an airline decision, and your airline is the only source for what happens to a specific flight number.
- Why does the end time keep moving?
- Because it is a forecast, not a schedule. The FAA publishes an expected end time when it issues a program and revises it as conditions change, so a stop first posted to end at 16:30 can be pushed to 17:15 and then 18:00. That is normal, and it is exactly why the end time is worth watching rather than trusting.
- What can I fly out of instead of San Francisco?
- The alternatives on this page are the other airports serving the same metro, with their live FAA status beside them. A weather event usually hits a whole region at once, so a neighbouring airport being clear is worth checking but not worth assuming — and re-booking is your airline's call, not ours.
- Where does this come from?
- Live FAA airport status — the same upstream that powers the FAA's Air Traffic Control System Command Center, including the issued and scheduled end times most tools drop. We refresh every minute. If something looks off, the FAA's official status page is always authoritative.
