Does SFO fog delay qualify for US DOT refund?

Yes, if delay exceeds 3 hours domestic or 6 hours international at final destination arrival. Cause does not matter for the refund. Duty of care is not required for weather-caused delays.

How do I know if a delay was weather or controllable?

Ask the crew at the gate what the stated cause is. Screenshot the airline app's cause announcement. The FAA's daily operations report can corroborate. Burden of proof for controllable cause is on the airline if you challenge.

Can I get meals and hotel for a controllable SFO delay?

Yes, under the airline's customer service plan for controllable delays (crew, mechanical, scheduling). Cite the plan at the gate. If denied for a delay that was clearly controllable, file a DOT complaint.

What if I have a tight connection at SFO?

If the first leg of your itinerary was delayed and caused you to miss the connection, the airline must rebook on next available flight at no charge. If a cash refund makes more sense, you can take that and self-book.

Does morning fog happen all year at SFO?

Most common May through October. Winter fog events happen but are rarer. Winter weather delays are more often from atmospheric rivers (heavy rain).

Is the DOT compensation the same for domestic and international delays?

Different thresholds. Domestic threshold is 3 hours; international is 6 hours. Both trigger cash refund rights under DOT 2024 rule. Compensation amounts are refund of unused fare; additional cash compensation (like EU261) does not exist in US DOT.

Should I take a refund or rebook on an SFO delay?

Refund if you can find a better option on another carrier. Rebook if the airline's next flight is reasonable. Vouchers are not equivalent to cash refund; refuse vouchers in favor of cash.

San Francisco (SFO) Flight Delays: How to Claim Compensation

SFO delays cluster in morning (fog) and late afternoon (onshore flow). The DOT 3-hour domestic and 6-hour international thresholds trigger refund rights. Here is how to claim compensation when your SFO flight runs long.

SFO Delay Patterns

San Francisco (SFO) flight delay compensation rights follow the DOT 2024 refund rule and depend on delay duration at final destination. SFO's delay patterns are predictable:

›
Morning stratus: 5 to 11 AM delays May through October, peaking June through August.
›
Late afternoon onshore flow: 3 to 8 PM evening fog in summer months.
›
Winter rain: atmospheric river events add December through March delays.
›
ATC flow control: Northern California TRACON issues trigger holds.
›
United late-bank cascade: afternoon and evening aircraft swaps compound delays.

Compensation Thresholds

Your rights kick in at:

›
Domestic flight, 3-hour arrival delay: cash refund eligible.
›
International flight, 6-hour arrival delay: cash refund eligible.
›
Controllable cause (crew, mechanical): duty of care (meals, hotel).
›
Weather or ATC cause: refund only, no duty of care required.

Delay is measured at arrival at final destination, not at departure from SFO. A flight that leaves SFO 1 hour late but lands 3+ hours late at destination triggers the rule.

Claim Process

1
At the gate: screenshot airline app with delay details.
2
Note cause: ask crew or check FAA data for the stated cause.
3
Keep receipts: meals, ground transport, hotel if overnight.
4
Within 24 hours: file claim via airline website.
5
Cite DOT 2024 rule explicitly.
6
Follow up at 30 days.
7
Escalate to DOT if airline denies or stays silent after 45 days.

Airline-Specific Angles

United dominates SFO. For airline-specific delay guides see Alaska Airlines flight delayed 3 hours, Frontier flight delayed 3 hours, and Newark (EWR) flight delays how to claim compensation for the sister hub with similar United exposure.

International SFO Delays

For SFO-originating international flights, DOT refund rule applies on the outbound. EU261 does not (it covers EU departures). For the return leg (say, Tokyo to SFO on ANA, or Frankfurt to SFO on Lufthansa), EU261 may apply if the carrier is an EU airline.

Note that ANA is not an EU carrier, so an ANA NRT-SFO delay is not EU261 covered. A Lufthansa FRA-SFO delay on the EU-departure side is EU261 covered. See Lufthansa EU261 claim guide for the tactical details.

Duty of Care Specifics

For controllable delays at SFO:

›
United customer service plan: meal vouchers at 4 hours of controllable delay, hotel for overnight.
›
Alaska: meal vouchers at 3 hours, hotel if overnight and controllable.
›
Delta: similar to United.
›
Southwest (at OAK): similar but less formalized.
›
Budget carriers: limited duty of care, often just water and snacks.
