US Automatic Flight Refund Rule: What Counts as a Significant Change
The US automatic refund rule explained: which cancellations and schedule changes count as a significant change, and how fast airlines must refund you.
Under the US automatic refund rule, if a US airline cancels your flight or makes a "significant change" to it, you can decline the alternative it offers. Once you decline, you are owed a full cash refund, and the airline must pay it without you having to ask.
This applies to every fare, including basic economy and "non-refundable" tickets. The table below shows exactly what counts as a significant change. The rest of this guide covers what doesn't count and how to make sure you actually get paid.
Where the rule comes from
The US Department of Transportation (DOT) issued its final rule, "Refunds and Other Consumer Protections," in April 2024. It is written into federal regulations at 14 CFR Part 260. It has been in force since late October 2024 and was reinforced by the FAA Reauthorization Act of 2024.
Before this rule, airlines set their own definitions of a significant change. The rule replaced those with one national definition. As of October 2026, that definition is the one airlines must follow. You can read the current text at transportation.gov/airconsumer.
What counts as a significant change
Any one of these is enough:
| Change | Domestic itinerary | International itinerary |
|---|---|---|
| Scheduled departure or arrival time moved | More than 3 hours, earlier or later | More than 6 hours, earlier or later |
| Different departure or arrival airport | Counts | Counts |
| More connections than you booked | Counts | Counts |
| Lower class of service (e.g. business to economy) | Counts | Counts |
| Aircraft swap that significantly downgrades amenities, services or accessibility | Counts | Counts |
People often miss three details.
Earlier counts too. A scheduled departure or arrival moved earlier by more than the threshold qualifies, just as a later one does. Airlines sometimes present an earlier flight as a favor, but the rule treats both directions the same way.
"Domestic" is strict. An itinerary counts as domestic only if every segment is within the US. If one leg touches another country, such as a connection through Toronto or a return from Cancún, the whole itinerary is international and the 6-hour threshold applies.
Either end can trigger it. The test looks at both the scheduled departure time and the scheduled arrival time. Suppose the airline retimes your domestic flight so it leaves at the same time but is scheduled to arrive more than 3 hours later. That qualifies, even though the departure barely moved.
Here is one worked example. Say your domestic flight was scheduled to land at 4:00 p.m., and the airline changes the schedule so it lands at 7:30 p.m. The difference is 7:30 minus 4:00, which is 3 hours 30 minutes. That is more than 3 hours, so the change is significant. If the new scheduled arrival had been 6:45 p.m., the difference would have been 2 hours 45 minutes, and the time change alone would not qualify.
What about delays on the day?
The refund is for travel you don't take. If your flight runs late and you board it, this rule does not require a refund, however long the wait.
If a long delay makes you think about not flying at all, ask the airline through its app, website or chat whether it will refund you if you don't travel, and keep a copy of its answer. DOT's current guidance at transportation.gov/airconsumer explains how the rule applies, so check it before you decide.
A long delay may also earn you help under the airline's own customer-service commitments, such as meals or rebooking. That is covered further down.
To follow a delay as it unfolds, check the live times on our flight status page. Our guide on how to read a flight status explains what "delayed," "estimated" and "cancelled" actually mean. For an early hint that a delay is coming, see how to find the inbound aircraft for your flight. The inbound aircraft is the plane flying in to operate your flight.
How the refund must be paid
Once you decline the alternative, or if the airline doesn't offer one, the rules on payment are clear:
- Automatic. You don't need to fill in a form or keep calling.
- In full, to the original form of payment. Cash goes back as cash, card charges go back to the card, and points go back as points. You only get a voucher if you choose one.
- Fast. The airline has 7 business days to refund a credit-card purchase and 20 calendar days for other payment methods.
- Unused portion only. If you flew the outbound and the return was cancelled, the return is refunded.
The airline will often offer a voucher or travel credit first. Taking it is your choice, and you can insist on cash instead. Vouchers can have expiry dates and restrictions, so think before you accept one just to end the conversation.
If you booked through a travel agent or online agency, the business that took your payment is responsible for the refund. That is often the airline and sometimes the agency. The timelines are the same either way.
Fees and extras you can also get back
The rule goes beyond the ticket price. You're also owed refunds for:
- Checked-bag fees when the bag is significantly delayed. On a domestic flight, that means the bag isn't delivered within 12 hours of the plane reaching the gate. On an international flight, the limit is 15 hours for flights under 12 hours and 30 hours for longer ones. You must file a mishandled-baggage report for this to apply.
- Paid extras you didn't receive. This covers Wi-Fi that didn't work, a seat assignment you paid for and didn't get, in-flight entertainment, and similar add-ons.
There is also a separate provision for illness. If you can't travel because of a serious communicable disease and you provide documentation, the airline must give you a transferable travel credit. The credit must not expire, or must last at least five years. This is a credit, not a cash refund.
What the rule doesn't do
The US rule gets you your money back. It does not pay you extra for the inconvenience. That is the big difference from Europe's EU261, which can pay fixed cash compensation for long delays. If your trip involves Europe, see our EU261 compensation guide.
Anything beyond a refund depends on each airline's own customer-service commitments, and what each airline offers varies. Typical examples are meal vouchers and help with rebooking. DOT publishes these commitments on its airline dashboard, which is worth checking before you argue at the gate.

How to protect your claim
- Keep the airline's change notice. Save the email or app message. It proves the change was the airline's doing, not yours.
- Check your booking after any notice. Airlines often retime flights months ahead. Your right to a refund begins when the change is made, not when the flight date arrives.
- Compare old and new times yourself. Look at both the scheduled departure and the scheduled arrival, and work out the difference. Don't rely on the airline calling a change "minor."
- Decline the alternative through the app, site or chat. Once you've declined, the refund follows automatically, with no form or further chasing needed. Keep a copy of your message. Something this simple works: "I do not accept the new flight you have offered. Please cancel my booking and refund the unused ticket to my original form of payment."
- Complain if payment stalls. If the refund hasn't arrived after 7 business days (for a card) or 20 calendar days (for other payment methods), file a free complaint at transportation.gov/airconsumer. Airlines are required to respond.
Frequently asked questions
Does the rule apply to basic economy and non-refundable tickets?
Yes. The refund right applies to every fare type when the airline cancels or significantly changes the flight and you don't accept the alternative. "Non-refundable" only limits refunds when you are the one who changes your plans.
My flight was moved 2.5 hours earlier. Can I get a refund?
Not on the time change alone. The threshold is more than 3 hours for domestic trips and more than 6 hours for international ones. If the change also added a connection or switched airports, that alone would qualify.
My flight was delayed four hours on the day, but I still flew. Am I owed a refund?
No. The refund covers travel you didn't take. If you flew the late flight, the rule doesn't require a refund. The airline's own customer-service commitments may still entitle you to meals, rebooking or other help.
