If an airline cancels your flight, decide whether you want your money back or another way to travel before you accept a voucher or a replacement. In the United States, you can usually request a refund to your original form of payment when the airline cancels or significantly changes the flight and you don't take the alternative. For a flight covered by EU 261, you can usually choose reimbursement or rerouting, with possible care and fixed compensation.

Make the choice in writing. Save the cancellation notice, your original itinerary, the replacement offer, and the airline's case number.

Quick answer: where to complain after a flight cancellation

Start with the airline that operated the flight. If a travel agency or online travel agency sold or issued the ticket, send the same request there and ask who will process the payment refund. A phone call at the airport can get you moving that day. It isn't a substitute for a written record.

A travel credit is not a cash refund. If you want money returned to the original payment method, say so before you accept a voucher or a replacement flight.

Which passenger rules apply

Look at the route and the operating carrier, not only the airline whose logo appears on your booking.

• U.S. rules: Department of Transportation refund protections generally cover air transportation to, from, or within the United States.
• EU 261: The regulation generally covers flights departing from an EU airport on any airline, and flights arriving in the EU from outside the EU when an EU airline operates the flight.
• UK flights: The United Kingdom has a separate UK261 regime. Use UK rules for a UK claim rather than assuming EU 261 applies.
• Package holidays: If the flight was sold as part of a package, notify the tour operator as well. The package contract and applicable package-travel rules may affect the remedy.
• Codeshares: Identify the airline that operated the aircraft, then include the ticket seller if it issued the ticket or took your payment.

A Paris-to-New York flight can fall under EU 261 even if a U.S. airline operates it. A New York-to-Paris flight on a U.S. airline isn't covered by EU 261 merely because it lands in Europe.

U.S. flight cancellation refund rights

When a U.S. refund is normally due

You can request a refund when the airline cancels your flight and you don't accept the replacement. The same principle can apply when the airline makes a significant schedule change or other major change.

A refund normally covers unused air transportation, prepaid baggage, seat, or other ancillary services the airline didn't provide, and other eligible charges tied to the unused transportation.

A nonrefundable fare doesn't usually block that refund after the airline cancels or significantly changes the flight. It can still block a refund when you cancel simply because you no longer want to travel.

If you accepted and used a replacement flight, don't automatically claim the full original ticket price. Ask about any unused segment or paid service that wasn't provided, and explain exactly what happened.

What counts as a significant change

Under the DOT thresholds described in the Federal Register rule on airline refunds and consumer protections, a significant change can include:

• a scheduled arrival at least three hours later on a domestic flight;
• a scheduled departure at least three hours earlier on a domestic flight;
• a scheduled arrival or departure at least six hours different on an international flight;
• a change to a different origin or destination airport;
• an added connection;
• a cabin downgrade; or
• a paid ancillary service that the airline fails to provide.

Compare the original and revised itineraries. The arrival time alone may not tell the whole story.

What U.S. law usually doesn't provide

The United States doesn't have a general fixed cancellation payment of €250, €400, or €600. Those amounts come from EU or UK passenger-rights systems when their requirements are met.

Federal rules also don't generally require meals, hotels, or replacement ground transportation after every cancellation. An airline may still offer those benefits under its customer-service policy, especially for disruptions within its control. Travel insurance may cover some extra costs, but the policy's exclusions and covered reasons control.

A refund for the unused ticket is different from reimbursement for a missed hotel, event, or rental car. Don't fold every expense into the word "compensation."

U.S. refund timing

DOT rules generally treat a refund as prompt when it is processed within seven business days for a credit-card purchase, or within 20 calendar days for cash, check, or other applicable non-credit-card payments.

If an agency sold the ticket, ask whether the airline or the agency is issuing the refund and get that answer in writing. A dispute about which business must process the payment shouldn't stop you from keeping both informed.

EU 261 cancellation refunds and compensation

The official text of EU Regulation 261/2004 sets out the main cancellation rights. The route, operating carrier, notice period, replacement itinerary, and reason for cancellation all matter.

Your choice: reimbursement or rerouting

For a covered cancellation, you can generally choose one of these options:

1. Reimbursement of the ticket, normally within seven days;
2. Rerouting to your final destination at the earliest opportunity; or
3. Rerouting at a later date that suits you, subject to available seats.

Pick the ticket remedy that fits your plans. If you select reimbursement, don't buy an expensive replacement and assume the airline must pay for both. Ask the carrier to confirm your choice before you book another flight. If the airline failed to offer a required rerouting option, explain that in your complaint and keep proof of the replacement cost.

Meals, hotels, and other care

If you wait for rerouting, the airline may have to provide reasonable meals and refreshments in relation to the waiting time, hotel accommodation if an overnight stay becomes necessary, and transportation between the airport and the hotel.

Ask for vouchers at the airport first. If the airline has no staff or refuses to provide the required care, keep itemized receipts and choose reasonable, not luxury, alternatives. Care can remain available even when an extraordinary circumstance means fixed compensation isn't payable.

When fixed compensation may be due

A qualifying cancellation may lead to a fixed payment in addition to reimbursement or rerouting and care. The usual distance bands are:

The payment isn't automatic. Notice and rerouting can remove or reduce it:

• If you were told more than 14 days before departure, fixed compensation generally isn't due.
• If notice was between seven and 14 days before departure, compensation generally isn't due when the replacement leaves no more than two hours earlier and arrives less than four hours later.
• If notice was less than seven days before departure, compensation generally isn't due when the replacement leaves no more than one hour earlier and arrives less than two hours later.
• If the airline proves an extraordinary circumstance, such as certain severe weather, air-traffic-control restrictions, security events, or external strikes, fixed compensation may not be due.

"Outside our control" is not a sufficient explanation by itself. Ask the airline to identify the specific event, explain how it affected your flight, and provide the basis for its decision.

If you accept rerouting and reach your final destination within the applicable shorter delay limits, the airline may reduce the fixed payment by 50 percent. That payment is separate from a ticket reimbursement and reasonable care expenses.

For a single-booking connection, the final destination, total distance, and arrival delay can affect the calculation. Include the entire itinerary rather than calculating only the canceled leg.

How to file a flight cancellation complaint

1. Record the cancellation

Save the email, text message, app alert, and airport announcement. Note the date and time you received the notice, because the notice period can affect an EU or UK compensation claim.

Collect the booking confirmation and ticket number, passenger names and confirmation code, original and replacement itineraries, boarding passes or check-in records, operating carrier and ticket seller, screenshots of vouchers or rebooking offers, payment records, receipts for meals, lodging, transport, or other care, previous correspondence and case numbers, and the airline's stated cancellation reason.

A flight-tracking screenshot may show that a disruption occurred. It rarely proves the legal cause. For an extraordinary-circumstances dispute, the airline's explanation and supporting records are more useful.

2. Choose one primary ticket remedy

State clearly what you want.

For a U.S. cancellation, request a refund to the original form of payment and say whether you rejected or did not use the replacement. If only one part of a longer itinerary went unused, identify that segment and ask the airline to explain how it calculated the refund.

For an EU or UK claim, choose reimbursement or rerouting first. Then make separate requests, if the facts support them, for fixed compensation and reasonable care expenses.

Don't describe a voluntary decision not to travel as an airline cancellation. That distinction can determine whether a refund is available.

3. Contact the right businesses

Use the operating airline's refund or complaint form. Send the same request to the agency or online travel agency if it issued the ticket or charged your payment method.

If a business tells you to contact someone else, ask it to identify its role in writing: who accepted the payment, who issued the ticket, who canceled or changed the flight, who will calculate and send the refund, and which case number you should use for follow-up.

Use a secure portal for payment or identity documents. Don't send a full credit-card number, passport scan, or bank login through ordinary email.

4. Separate the amounts you request

List each remedy on its own line: unused fare or transportation; prepaid baggage, seat, or other services not provided; EU or UK fixed compensation, if applicable; reasonable meals, lodging, and local transport; and losses you are sending to travel insurance instead of the airline.

That split makes it easier to see what the airline approved, denied, or ignored. It also helps prevent double recovery for the same receipt.

5. Send a short timeline and deadline

A clear timeline beats a long narrative. Include the scheduled flight and route, when and how the cancellation notice arrived, what replacement was offered, whether you accepted or used it, what remedy you selected, your documented expenses, and the total amount requested.

Attach readable copies and name the files. You can ask for a written response within 14 days, but that is a practical request, not a universal legal deadline. File promptly, because court and claim deadlines vary by jurisdiction.

6. Preserve the response

Save the airline's approval, payment promise, processing date, and final denial. If it rejects the claim, ask for the exact reason and the rule or policy it relied on.

An automated message saying that your claim is ineligible isn't a regulator's decision. Ask for a human-readable explanation tied to your route, notice period, replacement timing, or cancellation reason.

If the airline rejects your claim

"Your fare was nonrefundable." Explain that the airline canceled or significantly changed the flight and that you didn't accept the alternative. A voluntary-cancellation fare rule is not the same as a carrier-initiated cancellation.

"The cancellation was weather-related." For a U.S. refund, weather generally doesn't remove the refund when you reject the replacement. Under EU or UK rules, weather may defeat fixed compensation while leaving reimbursement, rerouting, and care rights in place.

"You were a no-show." Send the cancellation notice and explain whether you declined or used the replacement. Don't claim an airline cancellation if you simply chose not to travel.

"We issued a travel credit." State whether you accepted it. If you didn't, repeat that you want a refund to the original payment method.

"Contact the travel agency." Send the request to both the agency and the airline, identify who charged your card, and ask each business to confirm its role.

"The cancellation was outside our control." Ask for the specific event and its connection to your flight. A general label doesn't show whether an EU or UK extraordinary-circumstances exception applies.

If you still haven't been paid

United States

After giving the airline a written opportunity to resolve the matter, you can file an Aviation Consumer Protection complaint through the DOT route described in the FAA's airline service complaint guidance.

Include the airline's case number, itinerary, cancellation notice, refund request, response, payment record, and a short statement of what remains unpaid. DOT complaints can help identify compliance problems, but DOT isn't your private lawyer and a complaint doesn't guarantee an individual payout.

If you paid by credit card and a promised refund hasn't posted, ask the card issuer promptly about its billing-dispute process. That process has separate eligibility requirements and deadlines, and a dispute isn't automatically successful. Travel insurance is another possible route for covered hotels, transport, or other losses the airline doesn't reimburse.

EU and UK

For an EU 261 dispute, complain to the airline first. If it doesn't resolve the issue, identify the appropriate national enforcement body, usually through the official passenger-rights authority for the country connected to the flight. You can also check whether the airline participates in an approved alternative-dispute-resolution scheme.

For a UK flight, follow the UK Civil Aviation Authority's cancellation guidance and the relevant process described in Citizens Advice guidance on delayed or canceled flights.

A regulator may assess compliance without awarding every item of a private claim. Keep your airline correspondence, receipts, and any ADR filing active where appropriate. Court limitation periods vary by country, so don't wait indefinitely after a final refusal.

Should you use a flight claims service?

Companies such as AirHelp and Flightright are optional private claims services, not government agencies. Filing yourself is usually the simplest route for a straightforward refund.

Before authorizing a claims service, check the fee and whether it applies to refunds, fixed compensation, expenses, or all recovered money; any additional charge if legal action begins; who controls settlement; whether you can cancel the authorization; what happens if the airline pays you directly; and whether the service is handling a refund claim, a compensation claim, or both.

Compare the likely recovery with the total cost before signing.

Frequently asked questions

Can I receive both a refund and EU compensation?

Often, yes. A refund returns unused ticket value, while EU compensation addresses a qualifying cancellation. Care expenses can be separate as well. You generally can't recover the same expense twice, and choosing rerouting instead of reimbursement can change the calculation.

Do U.S. passengers receive €250 to €600 for a canceled flight?

No. Those figures come from EU or UK passenger-rights rules when the route and cancellation qualify. U.S. rules generally focus on a refund after an airline cancellation or significant change, not a fixed inconvenience payment.

Does bad weather eliminate a flight refund?

For a U.S. airline cancellation, weather generally doesn't eliminate a refund when you reject the replacement. For EU or UK claims, weather can eliminate fixed compensation while leaving reimbursement, rerouting, and care rights in place.

Can I buy my own replacement flight?

Ask the airline to confirm your selected remedy before paying for another ticket. If you are waiting for EU or UK rerouting and the carrier doesn't provide required assistance, keep receipts for reasonable costs. The treatment of a self-booked replacement can depend on what the airline offered and whether the expense was necessary.

How long should the complaint take?

A qualifying U.S. refund generally has DOT timing standards of seven business days for a credit-card purchase and 20 calendar days for cash or check. EU reimbursement is generally due within seven days after you choose that option. Compensation complaints may take longer, so escalate if the airline misses the applicable payment timing or stops responding.

Save the original itinerary and the exact cancellation timestamp, then send one written request that names the rule, the remedy you chose, the amount owed, and the documents that support it.
