Standfirst: If your flight is cancelled or changed by 3 or more hours, US rules say you can get a full cash refund. The rule is the U.S. Department of Transportation’s final rule “Refunds and Other Consumer Protections” (14 CFR Part 260), and its automatic-refund protections took full effect on October 28, 2024.
The rule in plain language
What the rule requires: The rule requires automatic refunds when a U.S. or foreign airline cancels a flight, or makes a significant change to a flight to, from, or within the United States, and the passenger does not accept alternative transportation, travel credits, or vouchers.
When it applies: The rule applies to flights to, from, or within the United States, and it applies to both U.S. and foreign airlines. It applies even to non-refundable and basic-economy fares, so a cheap ticket does not lose the protection.
What “automatic” means: The refund is due without you having to ask, if the airline offers no alternative, or if you reject the change or a voucher. That is the key point of the rule: you should not have to fight for the money to get it back. Keep records and follow up in writing if the refund does not arrive.
What you get back: Refunds go to the original form of payment, in the full amount paid — the fare plus taxes and fees — minus the value of any portion already used. If you flew part of the trip, the value of that part is taken off. If you flew none of it, you get the full amount back.
What counts as a significant change
The DOT definition: The DOT definition of a “significant change” was first set by this rule, and it has four parts. A change counts as significant if any one of them happens.
- Domestic time change: Departure moved 3 or more hours earlier, or arrival 3 or more hours later, on a domestic itinerary.
- International time change: Departure moved 6 or more hours earlier, or arrival 6 or more hours later, on an international itinerary. Note the difference: on a domestic trip the limit is 3 or more hours, and on an international trip it is 6 or more hours.
- Different airport: Departure from or arrival at a different airport than the one you booked.
- More connections: More connections than originally booked.
- Downgrade: A downgrade to a lower class of service.
How to use the list: The list is exact, and it is the test for whether you can claim a refund. If your flight is cancelled, the test is simple: the flight did not go. If your flight is changed, check the list. Was departure moved 3 or more hours earlier on a domestic trip, or 6 or more hours earlier on an international trip? Was arrival 3 or more hours later on a domestic trip, or 6 or more hours later on an international trip? Did the airport change? Are there more connections? Were you downgraded? If the answer to any one of those is yes, the change is significant, and the refund rule applies.
What does not count: The rule is about cancellations and significant changes, not about delays alone. The DOT considered a rule requiring cash compensation for delays caused by airlines, but that proposal was withdrawn in November 2025, so today cash is guaranteed only for cancellations and significant changes, not for delays alone.

Cash or voucher: your choice
The airline may offer a voucher: Airlines may offer travel credits or vouchers instead of a cash refund, but they must also tell you that you can have a cash refund. The offer of a voucher is not the same as a refund, and the airline cannot hide the cash option.
The voucher rules: Any credit offered must be valid for at least five years. That is a long time, and it means a voucher is not a short-term offer that runs out in a few months. Even so, a voucher is not cash, and you do not have to take it.
Your choice: If you do not accept alternative transportation, travel credits, or vouchers, the airline must give you an automatic refund. The choice is yours. If the voucher suits you, you can take it. If you want the money back, you can have it. The airline must tell you that the cash refund is an option.
If you accept the rebooking: If you accept the rebooked flight and fly it, you are NOT entitled to a refund of the fare. That is the trade-off. A rebooking gets you to your destination, but it ends the refund claim for that fare. Think before you accept: if the new flight works for you, take it and fly. If it does not work for you, do not accept it, and the refund is due.
How fast the money must arrive
The deadlines: Refunds must be prompt: within 7 business days for credit card purchases, and within 20 calendar days for other forms of payment. Those are two different clocks, so check which one applies to you.
Credit card purchases: If you paid by credit card, the refund must arrive within 7 business days. Business days are working days, not weekends, so count the days from the date the refund became due.
Other payments: If you paid by another form of payment, the refund must arrive within 20 calendar days. Calendar days include weekends, so the clock runs every day.
How the money comes back: Refunds go to the original form of payment. The refund is the full amount paid — the fare plus taxes and fees — minus the value of any portion already used.
Fees you did not use: Fees for services you did not receive are also refundable under the rule. For example, checked-bag fees if your bag was not delivered, or seat-selection fees for a seat you did not get, are refundable. If you paid for a service and did not receive it, that fee should come back too.
What you lose if you take the rebooking
The rebooking trade-off: If you accept the rebooked flight and fly it, you are NOT entitled to a refund of the fare. That is the clearest trade-off in the rule, and it is worth knowing before you say yes at the airport.
Before you accept: Ask yourself: does the new flight get you where you need to go, at a time that works? Does it change the airport, add connections, or downgrade your class? If the new flight works, take it. If it does not, do not accept it, and the refund is due.
If you reject the change: If you reject the change or a voucher, the refund is due without you having to ask. Keep records of the cancellation or change, of what the airline offered, and of what you said. Follow up in writing if the money does not arrive in time.
The 24-hour cancellation rule
A separate protection: Tickets bought directly from an airline at least 7 days before departure can also be cancelled within 24 hours of purchase for a full refund. This is a separate rule from the cancellation refund, and it applies even when the flight is still going ahead.
The two conditions: Both conditions must be met. First, the ticket must have been bought directly from an airline, not through a third party. Second, it must have been bought at least 7 days before departure. If both are true, you have 24 hours from the purchase to cancel for a full refund.
Why it helps: The 24-hour rule helps when you book the wrong flight, or change your mind soon after booking. It gives you a day to check the details, and to cancel without losing the fare. See also our guide to Thanksgiving turkey thaw and leftovers safety.
What to do: If you need to cancel, do it within 24 hours of purchase, and do it in writing where you can, so you have a record. Keep the confirmation, and check that the full refund comes back to the original form of payment.
If the refund never comes
Keep records: Keep records of everything: the booking, the cancellation or change, the messages from the airline, and what you were offered. Keep records and follow up in writing. A written record is the strongest proof you have, and it is what the DOT will want to see.
Follow up in writing: Follow up in writing if the refund does not arrive within 7 business days for a credit card purchase, or within 20 calendar days for other forms of payment. Write to the airline, give the booking details, and state that the flight was cancelled or significantly changed, and that you did not accept alternative transportation or vouchers.
File a free complaint: If a refund does not arrive in time, file a free complaint with the DOT’s Office of Aviation Consumer Protection at transportation.gov/airconsumer. The complaint is free. See also our guide on how to avoid drained holiday gift cards.
A final note: Flight cancellations spike in winter weather, and the holiday travel season is starting. Know the rule before you travel: if your flight is cancelled, or changed by 3 or more hours on a domestic trip, you can get a full cash refund.
