Flight Delayed or Canceled? Your Refund Rights in the US

US law does not require airlines to pay flight delay compensation in cash. What it does require, since October 28, 2024, is an automatic refund to your original form of payment when the airline cancels your flight or significantly changes it and you choose not to travel. The rest depends on the airline’s own promises, on bumping rules, and on Europe’s EU261 if your flight started there.

Automatic refunds since October 28, 2024

The DOT finalized its refund rule in April 2024, and Congress wrote the same requirement into the FAA Reauthorization Act of 2024 the following month. The rule covers flights to, from and within the US, on US and foreign airlines.

The trigger is simple: the airline cancels the flight or makes a significant change, and you reject the alternative it offers, whether that is a rebooking, a credit or a voucher. You don’t have to ask in a particular way or fill in a form. The airline must then refund the fare, taxes and fees:

• within 7 business days if you paid by credit card;
• within 20 calendar days for other payment methods.

If you accept a credit or voucher instead of cash, it must be valid for at least five years. A refund goes to the card or account you used; the airline can’t push a voucher on you as the default.

Significant delay: 3 hours domestic, 6 hours international

A delay becomes a “significant change” when the departure moves 3 hours earlier or the arrival moves 3 hours later on a domestic itinerary, or 6 hours on an international one. Other changes count too:

• a different departure or arrival airport;
• more connections than you booked;
• a downgrade to a lower class of service;
• a connection at a different airport;
• a change of aircraft that makes the trip less accessible for a passenger with a disability.

The clock runs on the arrival at your final destination, not on one leg. A 2-hour late departure that makes you miss a connection and arrive 4 hours late on a domestic trip qualifies.

One adjustment in 2026: under a DOT notice published on July 8, 2026, the agency won’t enforce the cancellation part of the rule against flights that were simply renumbered, as long as the passenger was rebooked and the trip was not significantly changed or delayed. That discretion runs until July 7, 2027, while the DOT reconsiders how it defines a canceled flight.

No federal cash for a long wait

A refund is not compensation. If you sit at the gate for five hours and then fly, US law owes you nothing beyond what your airline promises. A Biden-era proposal to make airlines pay cash for long controllable delays was formally withdrawn on November 14, 2025, so no such payment is coming at the federal level.

Two other rules still apply. Tarmac delays are capped at 3 hours on domestic flights and 4 hours on international ones before passengers must be offered the chance to get off, with food and water provided within the first 2 hours. And involuntary denied boarding, getting bumped from an oversold flight, carries real money.

Bumped: denied boarding compensation up to $2,150

When an airline bumps you against your will and gets you to your destination late, it owes a percentage of the one-way fare, with caps that rose on January 22, 2025:

Arrival delay (domestic)	Arrival delay (international)	Compensation
Under 1 hour	Under 1 hour	None
1 to 2 hours	1 to 4 hours	200% of the one-way fare, up to $1,075
Over 2 hours	Over 4 hours	400% of the one-way fare, up to $2,150

You can ask for a check or cash instead of a travel voucher. Volunteers who give up a seat in exchange for an offer are negotiating; the caps above only apply when you didn’t volunteer.

Meals, hotels and the DOT airline dashboard

For delays and cancellations caused by the airline itself, such as a crew shortage or a maintenance problem, the big US carriers have published commitments: meal vouchers for long waits, hotel rooms and ground transport for overnight cancellations, free rebooking. The DOT tracks those promises on its cancellation and delay dashboard, which covers Alaska, Allegiant, American, Delta, Frontier, Hawaiian, JetBlue, Southwest and United. Once a promise sits in an airline’s customer service plan, the DOT can enforce it.

Weather and air traffic control restrictions are not controllable, and those promises don’t apply. That is why gate agents choose their words carefully. A flight tracker helps here: FlightAware shows where the inbound aircraft is and how late it left, which often tells you more about the real cause than the departure board does. A ground stop shows up as a cluster of aircraft holding at their origins, and the air traffic control audio archives sometimes carry the controller’s explanation word for word.

Bags and paid extras that never happened

The 2024 rule also covers checked-bag fees. If a bag is significantly delayed and you file a mishandled-baggage report, the fee comes back: the threshold is 12 hours after arrival on a domestic flight, 15 hours on an international flight of 12 hours or less, and 30 hours on longer ones.

Fees for services you paid for and didn’t get are refundable too: Wi-Fi that never worked, a seat assignment lost to an equipment swap, an upgrade that wasn’t provided. Swaps are common enough that I check the seat maps again the day before any long flight, which leaves proof of what was paid for and what was delivered. These refunds are not automatic in practice; ask for them through the airline’s refund form after the trip.

EU261 for flights from Europe

If your flight departs from an airport in the European Union, or flies into the EU on an EU airline, EU Regulation 261/2004 applies. An arrival delay of 3 hours or more, a cancellation with short notice or a denied boarding earns fixed cash compensation by distance: €250 for flights up to 1,500 km, €400 up to 3,500 km, and €600 beyond that, which covers most transatlantic flights. Airlines are exempt for extraordinary circumstances such as severe weather or air traffic control strikes, but technical faults usually don’t count.

A US carrier flying Paris to New York is covered; the same airline flying New York to Paris is not. The UK runs its own version with amounts of £220, £350 and £520. The EU adopted a revision of the regulation in 2026 that keeps the 3-hour threshold and the same €250 to €600 range, with most of its changes applying from late 2027.

Filing a claim that gets paid

Here is a typical sequence. Your Saturday flight is canceled at 6 p.m. and the airline rebooks you on Monday. You decline the new flight, book a cheaper option yourself and wait. If you paid by card, the refund for the canceled ticket must arrive within 7 business days. If it doesn’t, file a complaint with the DOT’s consumer office, then dispute the charge with your card issuer, attaching the cancellation notice.

I keep the original confirmation email and every change notice in one folder until the money lands. Booking direct with the airline makes all of this easier, since an agency in the middle adds a second company and a second queue. Readers comparing Google Flights results against an agency’s lower price should weigh that, and fare alerts are worth keeping on even after booking: if the price drops on an airline without change fees, you can rebook and pocket a credit.
