The board changes to “Cancelled” and the queue at the desk doubles. What happens in the next twenty minutes usually determines whether you travel today, and whether it costs you anything.
Most of what people believe here is either out of date or borrowed from a different country’s rules. The gap that matters most: in the United States you have a strong right to your money back, and almost no right to compensation on top of it. In Europe, the opposite is closer to true.
Here is what is actually enforceable, and what to do while everyone else is queueing.
The first twenty minutes
The most useful thing to know is that the desk is not your only option, and is usually the slowest.
- Get in the queue anyway, and work the other channels while standing in it.
- Call the airline at the same time. Non-US numbers are frequently far less congested during a disruption affecting one country.
- Open the app. Many carriers push self-service rebooking during mass disruptions, often before the agents have been briefed.
- Look up the alternatives yourself. Arriving with “there are two seats on the 18:40 through Chicago” changes the conversation entirely.
- Do not accept a voucher reflexively. Accepting travel credits is, in most cases, giving up the cash refund you were entitled to.
That last point is the expensive one, and it is the one airlines are most efficient at.
Refund or rebooking is your choice, not theirs
Under U.S. Department of Transportation rules, if the airline cancels your flight — regardless of the reason, weather included — and you choose not to travel, you are entitled to a refund of the ticket price. The DOT sets this out in its guidance on refunds.
“Regardless of the reason” is the part that surprises people. Weather is not the airline’s fault, and it does not remove your right to your money back if you decide not to fly.
What removes the right is taking the flight anyway. If you accept the rebooking and travel, the fare is no longer refundable — so the decision has to be made before you board, not after you arrive irritated. Airlines are also required to tell you the right exists, through whichever channel you subscribed to for notifications.
What counts as “significant”
A delay or schedule change only triggers the refund right once it crosses a defined line. The DOT thresholds are specific:
| Change | Domestic | International |
|---|---|---|
| Departs earlier than scheduled by | 3 hours or more | 6 hours or more |
| Arrives later than scheduled by | 3 hours or more | 6 hours or more |
| Different origin or destination airport | Always significant | |
| More connections than booked | Always significant | |
| Involuntary downgrade | Always significant | |
Two details there are worth pulling out. A flight moved earlier counts, not only a late one — a departure pulled forward by four hours qualifies. And an extra connection counts on its own, even if you still land at roughly the same time.
On downgrades: if you are moved to a lower class and travel anyway, you do not get the whole fare back, but the airline must refund the difference between what you paid and the fare for the class you actually flew.
Where the United States stops: compensation
The DOT publishes an airline cancellation and delay dashboard recording what each major U.S. carrier has committed to when the disruption is within the airline’s control — a crew or maintenance problem rather than weather. Across the nine carriers listed, the commitments are strong on some things and unanimous on one:
- Rebooking on the same airline at no cost — every carrier commits to it.
- A meal or meal voucher once the wait passes 3 hours — every carrier commits to it.
- Rebooking on a partner airline — several do not, which matters most when your original carrier has one flight a day on that route.
- Hotel and ground transport for an overnight disruption — most commit, not all.
- Cash compensation for a wait of 3 hours or more — not one of them commits to it.
“Controllable” is doing a lot of work
Everything on that dashboard applies only when the airline caused the problem. Weather, air traffic control and security events are outside it, which is also why the reason given for a delay is sometimes disputed. The refund right above is not limited this way — a cancellation entitles you to a refund whatever the cause.
Europe runs on a different principle
The EU rules do what the U.S. rules largely do not: they attach compensation to the disruption itself, on a fixed scale, separate from any refund. The official summary of EU air passenger rights sets out when they apply. The scope is broader than most people assume:
- Any flight within the EU, on an EU or non-EU airline
- Any flight departing the EU for a non-EU country, on any airline
- A flight arriving in the EU from outside it, but only on an EU airline
The rules also cover Iceland, Norway and Switzerland. So a traveller flying Lisbon to New York is covered on the way out regardless of carrier — and on the way back only if they booked a European airline.
One practical consequence: if you are denied boarding, cancelled, or delayed more than 2 hours at departure, the airline must hand you a written notice of your rights. If nobody offers one, asking for it tends to change the tone of the conversation.
The 24-hour rule, correctly stated
For tickets bought at least seven days before departure, U.S. rules require airlines to do one of two things: allow you to cancel for a full refund within 24 hours, or allow you to hold the price for 24 hours without paying.
Airlines are not required to offer both, which is the detail most write-ups get wrong. It also does not entitle you to free changes — cancelling and rebooking is the mechanism, not editing the ticket. Our guide on finding cheap flights without fake deals covers using this deliberately rather than as an emergency measure.
If your bag does not arrive
A delayed bag has its own rules, and one is frequently unclaimed: if you paid a checked baggage fee and the bag is lost or significantly delayed, that fee is refundable. The DOT covers this in its guidance on lost, delayed or damaged baggage.
There is no universal definition of “lost”. Most airlines declare a bag lost somewhere between 5 and 14 days, and the exact point varies by carrier — which is why the claim has to be filed immediately rather than when you give up hope.
Airlines also commonly exclude liability for fragile items, electronics and cash. That exclusion is in the contract you already agreed to, and it is why those things belong in the bag that stays with you — see the carry-on only packing system.
The trap that catches experienced travellers
If your journey is booked as two separate tickets, a delay on the first one is not the second airline’s problem. They owe you nothing, because as far as their contract is concerned you simply failed to show up.
This is how a cheap self-connected itinerary turns into a full-price replacement ticket. A single ticket, even across partner airlines, makes the onward connection the carrier’s responsibility. The saving on separate tickets is real; so is the risk.
Where insurance actually fits
Insurance does not duplicate the refund right above. What a policy may cover is the layer underneath: the hotel night, the missed prepaid tour, the onward ticket you had to buy yourself.
Most policies impose a minimum delay before anything pays out, and require documentation from the airline. Getting the delay reason in writing before you leave the airport is the step people skip and regret. Our guide on what travel insurance actually covers goes through the exclusions that cause the most disappointment.
How to escalate
If the airline refuses something you are owed:
- Write it down at the airport. Flight number, scheduled and actual times, the reason given, and who you spoke to.
- Keep every receipt for what the disruption cost you.
- Complain to the airline in writing first, citing the specific rule rather than describing your weekend.
- Escalate to the regulator if that fails — the DOT in the U.S., or the national enforcement body of the EU country where it happened.
Citing the rule matters. “My flight was cancelled and I am entitled to a refund rather than a voucher” is answered differently from “this was unacceptable”.

Frequently asked questions
Do I get a refund if my flight is cancelled because of weather?
Yes, if you choose not to travel. The U.S. refund right applies whatever the reason. What weather removes is the layer of hotels, meals and rebooking commitments, which cover only disruptions within the airline’s control.
Can the airline make me take a voucher instead of cash?
No. Vouchers are an alternative, not a substitute. If you are entitled to a refund and prefer the money, decline the credit and ask for the refund.
How long a delay before I can ask for my money back?
Three hours domestic, six international, measured as either a later arrival or an earlier departure. A change of airport, an added connection or a downgrade counts on its own, whatever the timing.
What if I already took the rebooked flight?
Then the fare is not refundable, because you travelled. You may still be owed meals, a hotel, or a refund of fees for services you paid for and did not receive.
Am I owed compensation on top of the refund in the US?
Generally not. No major U.S. carrier currently commits to cash compensation for a controllable delay or cancellation, though several commit to credits or miles. This is the main practical difference from the EU system.
Do EU rules apply to my flight from the US?
Only if you fly an EU airline into the EU. Departing from the EU, any airline is covered; arriving into the EU, only EU carriers are. The rules also cover Iceland, Norway and Switzerland.
Is my checked bag fee refundable if the bag is delayed?
Yes, where the bag is lost or significantly delayed. It is separate from any claim for the contents, and it is frequently not refunded unless you ask.
