US Flight Cancelled or Delayed? Your Refund Rights in 2026 Explained
US airlines cancel or heavily delay thousands of flights every month. Unlike Europe, the United States does not require airlines to pay fixed cash compensation for delays. But since 2024 it does require something many travellers still do not know about: automatic cash refunds when a flight is cancelled or significantly changed and you choose not to fly.
Quick answer: If a US flight is cancelled or significantly changed (for example, delayed by three or more hours on a domestic flight or six or more hours internationally) and you decide not to travel, the airline must refund the full fare plus taxes and fees to your original payment method, without you having to ask. Vouchers are optional, not required.
1. The automatic refund rule in plain language
The US Department of Transportation (DOT) rule on airline refunds came into force in 2024. It applies to US airlines and foreign airlines flying to, from or within the United States.
You are entitled to a refund when:
- Your flight is cancelled, for any reason, including weather
- Your flight is significantly changed and you do not accept the change
What counts as a significant change
| Change | Domestic flights | International flights |
|---|---|---|
| Departure moved earlier | 3+ hours | 6+ hours |
| Arrival moved later | 3+ hours | 6+ hours |
| Different departure or arrival airport | Yes | Yes |
| Extra connection added | Yes | Yes |
| Involuntary downgrade to a lower class | Yes | Yes |
2. How and when you get your money
- Full amount: fare, taxes and airline fees, plus unused paid extras such as seat selection or Wi-Fi.
- Original payment method: no vouchers unless you agree.
- Deadline: within 7 business days for card payments and 20 calendar days for other payment methods (Wego summary of the DOT rule).
How you can lose the refund
You lose the right to a refund if you take the changed flight or accept rebooking or a voucher. If you want your money back, say so clearly in writing and do not board the replacement flight.
3. Is there cash compensation for delays?
No fixed federal payment exists. The DOT considered a rule that would have required cash compensation for delays caused by airlines, but it was withdrawn in November 2025. Today, cash is guaranteed only for:
- Involuntary denied boarding (overbooking), under long-standing DOT rules
- Flights covered by European or UK rules, such as a flight leaving London or Paris. See our guide to EU261 and UK261 compensation.
4. What airlines promise when delays are their fault
The DOT runs a public dashboard listing what each major US airline commits to when a delay or cancellation is within its control. According to the dashboard comparison, American, United, Delta, Southwest and JetBlue all commit to:
- Rebooking on the same airline at no extra cost
- A meal or meal voucher for delays of three hours or more
- A hotel room and transport for overnight delays
Some also rebook you on partner airlines or offer travel credits. These are company promises listed on the dashboard, so check the latest version before you fly.
5. Checked bag delays
If your checked bag is significantly delayed, you can get the bag fee refunded. The thresholds are 12 hours for domestic flights and 15 or 30 hours for international flights depending on the length of the long-haul segment. You must file a Mishandled Baggage Report with the airline first. Separately, airlines must reimburse reasonable, provable expenses up to liability limits.
6. What to do when your flight is cancelled
- Decide quickly: do you still want to travel, or would you rather have your money back?
- If travelling: use the airline app to rebook; it is often faster than the queue. Ask about partner airlines.
- If not travelling: request a refund in writing and do not accept a voucher.
- Keep receipts for meals, hotels and transport.
- If the airline does not refund you, file a complaint with the DOT’s Office of Aviation Consumer Protection.
7. Extra protection worth having
Some travel credit cards include trip delay insurance that pays for meals and hotels after a set number of hours. Standalone travel insurance can cover missed connections and non-refundable prepaid costs. Paying for flights with a credit card also gives you dispute rights if an airline fails to refund. Our guide on how to pay abroad covers which cards suit travellers.
Frequently asked questions
Does the refund rule apply if the cancellation was caused by weather?
Yes. Refunds for cancellations are due regardless of the cause. Weather only matters for compensation-style promises, not refunds.
Does it apply to foreign airlines?
Yes, for flights to, from or within the United States.
Can the airline force me to take a voucher?
No. You are entitled to a cash refund if you do not travel. Any voucher offered instead must remain valid for at least five years.
What if my flight is delayed by two hours?
That is not a significant change under the rule, so no automatic refund applies, though the airline’s own customer service commitments may still help.
Where do I complain if the airline refuses?
File a complaint with the US Department of Transportation’s Office of Aviation Consumer Protection.
