Why were flights at San Francisco disrupted?

A short-lived combination of weather and traffic constraints hit San Francisco (SFO), which cascaded into cancellations and missed connections. That wave has since eased — there are no active FAA ground stops, ground delays, or closures at SFO right now.

My SFO flight was just cancelled — what's the single fastest thing to do?

Get in two lines at once: call your airline and join the in-person rebooking line at San Francisco simultaneously, because hold times spike while a backlog clears. Come with a hard arrival deadline and two or three concrete alternate routings ready.

The disruption at San Francisco has eased — am I in the clear?

Mostly, yes. SFO schedules are recovering and there are no active FAA delay programs, ground stops, or closures at the airport now. That said, repositioned crews and aircraft can leave a few stragglers for a day or two, so if you're still stranded, rebook onto the earliest solid option and keep a backup ready.

Am I owed a refund or compensation if my SFO flight was cancelled?

Yes. When the airline cancels, you're owed a full refund even on a non-refundable fare — and under the US DOT rule it's paid automatically in cash. If you were stranded overnight on a controllable cancellation, many airlines also cover hotel and meals. On covered flights to/from the EU, EU261 can add up to €600 in cash.

How do I avoid getting caught out next time San Francisco melts down?

Have a ranked backup routing ready before you fly. The travelers who get home first aren't waiting on hold — they already know their next-best flights out of San Francisco. Paste your itinerary into Reroute ahead of time and keep the plan handy just in case.

SFO disruption recap

San Francisco disruption has eased — here's what to know

The recent disruption at San Francisco (SFO) has eased. Cancellations and delays at this airport have cleared, and there are no active FAA ground stops, ground delays, or closures at SFO right now.

Schedules are back to normal, but after a disruption repositioned crews and aircraft can still leave a few stragglers for a day or two. If you're still catching up at San Francisco — or you want to be ready the next time SFO gets hit — here's exactly what to do.

1. Assume any backlog at San Francisco will grow before it shrinks

When traffic backs up at San Francisco, aircraft and crews end up out of position and the ripple lasts hours — not minutes. Don't wait to see if your flight recovers; rebook onto the earliest solid option out of San Francisco while seats still exist.

2. Get in two lines at once

The moment you see a delay or cancellation at San Francisco, call your airline AND join the in-person rebooking line simultaneously. During a hub backup, phone hold times balloon past two hours — whichever channel reaches you first wins, so never rely on just one.

3. Route around San Francisco entirely

If San Francisco is stacked up, the fastest path home is often to avoid it. Ask specifically to be re-routed through a calmer hub, or into or out of a nearby alternate airport — a short drive can save you a lost day when your hub is congested.

4. Ask to be endorsed to another airline

Airport-wide disruptions can trigger endorsement to partner and even competitor carriers. Say it directly: “Can you endorse me to a partner airline or a nearby airport?” Agents rarely offer this while their own San Francisco flights are full — you have to ask.

5. Lock in a seat and keep a live backup

Confirm the new itinerary, screenshot it, and keep the next-best routing ready. When San Francisco is recovering, seats vanish and flights can re-cancel with little warning — a current backup is what keeps you moving instead of restarting from the back of the line.

6. Know what you're owed

If the airline cancels, you're entitled to a full refund even on a non-refundable ticket — and under the US DOT rule, cash back automatically. If you're stranded overnight on a controllable cancellation, many carriers owe hotel and meals. Don't accept a voucher when cash and coverage are on the table.

Build a recovery plan before your next SFO disruption

Paste your itinerary and your real arrival deadline. Reroute scans every carrier, hub, and open seat and hands you a ranked rebooking plan in minutes — free preview, no waiting on hold while the good seats disappear.
