US Flight Refund Rules: When Airlines Must Pay You Back (2026 Update)

For years, getting your money back from a US airline after a cancellation meant arguing with an agent who preferred to hand you a voucher. That changed with a federal rule adopted in April 2024 and phased in from late 2024. Today, if your flight is cancelled or significantly changed and you choose not to travel, the airline has to refund you – automatically and in cash. This guide covers what the rule says, how it stands in late 2026, and the important things US law still does not give you.

Who the rule applies to

The Department of Transportation (DOT) rule covers US and foreign airlines on flights to, from and within the United States, and also ticket agents such as online travel agencies that sell those flights. It applies to every fare type, including basic economy and non-refundable tickets.

The two triggers: cancellation and significant change

You are entitled to a refund when either of these happens and you do not accept the alternative flight, travel credit or other compensation the airline offers.

1. Cancelled flight. The rule defines a cancellation as a flight that was published in the airline's reservation system when you bought your ticket but was not operated. The reason does not matter – weather and air traffic control cancellations count just as much as crew shortages.

2. Significant change. The airline makes a significant change if:

• you would depart more than 3 hours earlier or arrive more than 3 hours later than scheduled on a domestic itinerary (6 hours for international);
• your departure or arrival airport changes;
• your itinerary gets more connections;
• you are downgraded to a lower class of service;
• for travellers with disabilities, a connection is moved to a different airport, or the substitute aircraft lacks an accessibility feature you need.

If you take the rebooking, fly on the new schedule or accept a voucher, you have generally given up the refund for that ticket. So check the offer carefully before clicking "accept".

How and when you get paid

If you paid by credit card and the airline misses the deadline, you can also dispute the charge with your card issuer.

Bag fees and other extras

The rule also covers money you paid on top of the fare:

• Checked bag fees must be refunded if you filed a mishandled baggage report and the bag was significantly delayed – not delivered within 12 hours of arrival on a domestic flight, 15 hours on an international flight of up to 12 hours, or 30 hours on longer international flights.
• Fees for services you paid for but did not get – seat selection on a flight you could not board, Wi‑Fi that never worked – must be refunded too.

Travel credits when you are told not to fly

If a government health authority or a doctor advises you not to travel because of a serious communicable disease, airlines must provide a transferable travel credit or voucher valid for at least five years rather than a cash refund. The airline may ask for documentation.

Where things stand in late 2026

The core refund rule is in force, and Congress wrote the basic right to a refund for cancelled flights into federal law in the 2024 FAA reauthorization. But two developments are worth knowing:

• Renumbered flights. Airlines complained that, under the rule's wording, a flight that operates normally under a new flight number counts as "cancelled". In December 2025 the DOT said it would not enforce refund requirements in that narrow case, as long as you are rebooked on the renumbered flight and it runs without a significant change or delay. In July 2026 this pause was extended until 7 July 2027. If a renumbered flight also has a big time change or a different airport, the normal refund rules still apply.
• A new rulemaking is pending. The DOT has proposed revisiting parts of the rule – including the definition of a cancellation, bag delivery times and automatic refunds of extra fees – under a rulemaking called "Airline Refunds and Other Consumer Protections III". No final changes had been adopted when we last checked.

What US law does not require

This is where US and European rules differ most.

• No cash compensation for delays or cancellations. In late 2024 the DOT began considering mandatory payments for airline-caused disruptions, but it formally withdrew that proposal in November 2025, saying it lacked the legal authority. A long delay entitles you to a refund if you don't travel, not to compensation on top.
• No legal right to meals or hotels. Many airlines promise these in their own customer service plans for disruptions they cause, and the DOT tracks those commitments – but they are airline policies, not federal law. Check the airline's contract of carriage.
• Involuntary bumping is the exception. If you are denied boarding on an oversold flight against your will, US rules do require compensation: up to $1,075 or $2,150, depending on how late you arrive, for travel since January 2025.

If your trip touched Europe or the UK, you may be protected by those rules instead – see our guides to EU261 and UK261.

If the airline won't pay

1. Turn down the alternatives in writing and ask for a refund to your original payment method.
2. Keep screenshots of the schedule change and of your refund request.
3. If the deadline passes, file a complaint with the DOT through its official air travel consumer website, and consider a dispute with your card issuer.
