Flight cancelled or changed? What US airlines actually owe you

Most people still believe a cancelled flight means a fight with an airline and a travel credit they did not want. That has not been true in the United States since 2024, and the gap between what people think they are owed and what they are actually owed is costing travellers real money. Here is where it stands as of September 2026, including one carve-out that is currently in force and that almost nothing written on this subject mentions.

You do not have to ask any more

The headline change is that refunds are now automatic. If the airline cancels your flight, or changes it significantly, and you do not accept what they offer instead, the refund is owed to you without you filing anything. No form, no phone queue, no negotiating with an agent who says the fare is non-refundable. The obligation sits with the airline.

It also has to be money. Refunds must go back to the original form of payment, whether that is a card, cash or miles. A voucher or travel credit only counts if you actively choose it. If an airline offers you a credit and you say nothing, that is not consent, and the refund is still owed.

The clock is defined too. Card purchases must be refunded within seven business days. Anything else has twenty calendar days.

What counts as a significant change

This is where most of the argument happens, so the thresholds are worth memorising. A departure or arrival time that moves by more than three hours on a domestic flight, or more than six hours on an international one, is a significant change. So is being moved to a different airport, having a connection added to what you booked as a nonstop, or being downgraded to a lower class of service than you paid for.

For passengers with disabilities there is an additional trigger: being moved to a connection or aircraft that is less accessible than the one booked counts as significant, even if the timings barely move.

The reason for the disruption does not matter. This is the part people get wrong most often. Weather, air traffic control, a crew shortage, a mechanical issue - none of it changes your right to your money back. Airlines may not owe you compensation for the inconvenience, but a refund for a flight you did not take is owed regardless of whose fault it was.

The renumbered-flight carve-out, which is live right now

Here is the part that is genuinely current and that most articles on this subject have not caught up with. In December 2025 the Department of Transportation paused enforcement of the refund obligation in one specific scenario: where an airline gives a flight a new number and rebooks passengers onto it, rather than cancelling outright. In July 2026 that pause was extended, and it now runs through July 2027 while the department works out a firmer definition of what a cancelled flight actually is.

In practice that means the word cancelled is doing a lot of work. If your flight disappears from the board and you are moved onto a differently numbered flight, the refund entitlement you would expect from a straight cancellation is not currently being enforced on the basis of the number change alone. Everything else in the rule still applies in full, and if the replacement flight also trips the three or six hour threshold, you are back on solid ground.

The practical move is simple: when something goes wrong, find out whether your flight was cancelled or renumbered before you decide what to ask for. It is a question worth asking explicitly, and the answer changes your position.

Bags and the extras you paid for

The same rule reaches past the ticket. If your checked bag is not delivered within twelve hours of a domestic flight arriving, the bag fee comes back. On international flights the window runs between fifteen and thirty hours depending on the length of the flight.

Anything else you bought and did not receive is refundable on the same principle. Wi-fi that never worked, a seat assignment you paid for and were then moved out of, in-flight entertainment that was broken on your seat. These are small amounts individually and almost nobody claims them, which is precisely why airlines are not in a hurry to remind you.

One related change worth knowing: a 2024 rule requiring airlines to disclose baggage and change fees more prominently was struck down in court, and in July 2026 the department formally rolled its own rule back to match. Fee transparency at the point of booking is therefore weaker than it was briefly meant to be, which is an argument for reading the fare rules before you pay rather than after.

Flying to or from Europe changes the picture

US rules give you your money back. They do not give you compensation for the disruption itself. Europe and the UK do, and the direction you are flying decides whether that applies to you.

Broadly, a flight departing an airport in the UK or the EU falls under those rules whatever airline you are on. A flight heading the other way, from the United States, generally only qualifies if you are flying a UK or EU carrier. So on a return trip the outbound and the homebound leg can sit under completely different regimes, and it is usually the leg home from Europe that carries the stronger entitlement.

That is worth knowing before you book a New York to London or New York to Paris itinerary, particularly a tight one over a holiday period. The amounts are banded by flight distance and there are exemptions for genuinely extraordinary circumstances, so we confirm what applies to a specific booking rather than quoting a figure in the abstract.

What we do about it

If we booked it, we chase it. That means establishing whether the flight was cancelled or renumbered, putting the refund request in writing against the right rule, and following the seven or twenty day clock rather than waiting to see what turns up. We also tell you when you do not have a claim, which saves everyone a fortnight.

If you booked elsewhere and are stuck, the thresholds above are the ones to quote. Ask in writing, name the rule, and decline the voucher in the same sentence.
