If an airline cancels your flight, decide first whether you still want to travel. In the United States, you can generally get a refund to your original payment method when the airline cancels or significantly changes the itinerary and you don't accept its alternative. That refund is not the same as compensation for inconvenience, which U.S. federal law usually doesn't require.

EU261 and UK261 can provide a refund or rerouting, care while you wait, and sometimes fixed compensation. Those rights depend on the route, operating carrier, notice period, replacement flight, and cause of the cancellation. Keep the U.S. refund process separate from an EU or UK claim.

Quick decisions after a flight cancellation

A voucher isn't the same as a refund. Don't accept one, or accept a replacement flight, until you've decided which outcome you want. Once you accept and use an alternative itinerary, getting a refund for the original unused ticket can become harder.

What to do at the airport

1. Save the cancellation notice. Screenshot the airline app, email, text message, airport display, and flight-status page. Record when you learned about the cancellation.
2. Ask for the reason. Request a written explanation if possible. Ask whether the cause was weather, air traffic control, aircraft maintenance, crew availability, or another event. The reason is particularly relevant to an EU261 or UK261 compensation claim.
3. Choose refund or rebooking. If you want a refund, state plainly that you're declining the alternative and won't use the canceled itinerary.
4. Ask for immediate assistance. Before paying for a hotel, meal, or transport, ask the airline what it will arrange. U.S. law doesn't require these benefits in every cancellation, but an airline policy, contract, insurance policy, or foreign passenger-rights rule might.
5. Record the replacement details. Save the original and new schedules. If you travel, note the time you ultimately reach your destination.
6. Keep reasonable receipts. Save proof of payment for necessary meals, lodging, ground transport, and communications. Avoid unusually expensive purchases unless the airline approves them or no reasonable option exists.

U.S. flight-cancellation refund rules

For a flight to, from, or within the United States, the U.S. Department of Transportation generally requires the airline or responsible ticket agent to provide a refund when it cancels the flight or makes a significant change and you don't accept the alternative offered.

What the refund should include

The refund generally goes to the original form of payment. It should cover the ticket price, including applicable taxes and fees connected with transportation you didn't receive. If you used part of the itinerary, the refundable amount may be limited to the unused portion.

DOT examples of a significant change include:

• A domestic itinerary that arrives at least three hours later, or an international itinerary that arrives at least six hours later.
• A departure moved substantially earlier.
• A change to a different origin or destination airport.
• An itinerary with an added connection.
• A downgrade to a lower cabin.

These examples don't resolve every schedule-change dispute. If the change is close to a threshold, ask the airline to explain how it classified the itinerary and why it believes no refund is due.

For eligible refunds, the usual processing periods are seven business days for credit-card purchases and 20 calendar days for other payment methods. The refund is intended to be issued automatically when the rule applies. If it doesn't arrive on time, send a written request to the airline or ticket agent and keep a copy.

What U.S. rules don't provide

The United States generally has no federal requirement for an airline to pay fixed cash compensation simply because a flight was canceled or delayed. A refund returns money for transportation you didn't receive. Compensation is an additional payment for disruption or inconvenience.

Federal law also doesn't require an airline to pay for a hotel, meal, or replacement ticket after every cancellation. Extra assistance can depend on:

• The airline's customer-service commitments.
• The fare contract or travel insurance policy.
• The cause of the cancellation.
• Whether you accepted the airline's rebooking.
• The terms of a separate hotel, rental-car, or tour booking.

Weather can affect an airline's decision about meals or lodging, but it doesn't normally remove the U.S. refund right for unused transportation when the airline canceled the flight and you declined the alternative.

When a U.S. refund may not apply

The DOT cancellation or significant-change refund rule usually isn't triggered when:

• You cancel voluntarily before the airline cancels or significantly changes the flight.
• You accept and use an alternative itinerary.
• The change doesn't meet the applicable significant-change standard.
• You received the transportation as booked and are seeking money only for inconvenience.

A voluntary cancellation might still qualify under a refundable fare, an airline waiver, a travel-credit policy, or travel insurance. Check those terms before canceling.

EU261 and UK261 cancellation claims

EU261 is separate from U.S. law. It commonly applies when:

• A flight departs from an airport in the European Union, regardless of the airline.
• A flight arrives in the EU from outside the EU and is operated by an EU airline.
• A qualifying connecting itinerary is booked under one reservation.

Separate tickets, codeshares, and itineraries involving the United Kingdom need closer review. UK261 is a separate regime with its own route rules. Don't assume that an itinerary qualifies under both systems. Check Your Europe's air passenger-rights FAQ for the EU framework and the UK Civil Aviation Authority's cancellation guidance for UK routes.

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

• Reimbursement of the ticket, usually within seven days.
• Rerouting to the destination at the earliest opportunity.
• Rerouting at a later date that suits you, subject to availability and the applicable rules.

A qualifying passenger may also receive fixed compensation. The refund or rerouting decision and the compensation claim are separate, so both can be available.

EU261 compensation amounts

The following table is for EU261 claims:

The amount can be reduced by 50% in some cases if the airline provides suitable rerouting and gets you to the destination within the permitted time window. Don't apply the euro amounts automatically to a UK261 claim; check the UK rules for the route and currency involved.

Notice and replacement-flight timing

For cancellations made less than 14 days before departure, the replacement flight's schedule is central to the compensation claim:

These tests apply to the specific itinerary and are also subject to the extraordinary-circumstances exception. Save both the original and replacement departure and arrival times. The UK Civil Aviation Authority's cancellation guidance includes timing examples for UK261 claims.

Extraordinary circumstances

An airline can avoid fixed EU261 compensation if it proves that extraordinary circumstances caused the cancellation and that reasonable measures could not have prevented it. Severe weather, some air traffic control decisions, airport closures, security events, and certain external strikes may qualify.

“Outside our control” doesn't provide enough detail to evaluate a denial. Ask the airline to identify the event, the relevant dates or flight restrictions, and why the cancellation could not reasonably have been avoided.

Routine aircraft maintenance problems aren't automatically extraordinary. The failure to maintain an aircraft correctly can point the other way. An airline's own staffing problem or employee strike may also be treated differently from a strike by airport staff or air traffic controllers. The facts and applicable case law matter.

Even if extraordinary circumstances eliminate fixed compensation, passengers may still have rights to reimbursement, rerouting, and care.

Meals and hotels under EU261

While waiting for qualifying rerouting, passengers may be entitled to reasonable refreshments, communications, and overnight accommodation, including transport between the airport and hotel. Ask the airline to provide these services first. If it refuses or no representative is available, keep itemized receipts and claim only reasonable costs.

Put the cancellation dispute in writing

A claim is easier to review when it asks for one clear remedy and identifies the facts supporting it. Gather:

• Booking confirmation, ticket number, and booking reference.
• Passenger names and boarding passes for every flown segment.
• The original schedule and any replacement schedule.
• Cancellation emails, texts, app notifications, and airport screenshots.
• The time you learned about the cancellation.
• The airline's stated reason and any written denial.
• Your actual final arrival time if you were rerouted.
• Receipts for necessary meals, lodging, transport, and communications.
• The credit-card or bank statement showing payment.
• Records of calls, chats, and earlier refund requests.

Don't send a full card number or sensitive identity documents through an unverified link. Use the airline's official website, app, or published customer-service address.

A practical claim template

Subject: Flight cancellation refund and compensation claim

Booking reference: [reference]
Passenger: [name]
Flight: [number] on [date]

The airline canceled or significantly changed the itinerary above. I declined the alternative offered [and did not use the canceled transportation].

Please return the eligible ticket amount to the original payment method and confirm the amount and processing date.

For this qualifying EU261 or UK261 claim, I also request the applicable fixed compensation and reimbursement of the attached reasonable expenses. If you deny compensation based on extraordinary circumstances, please identify the specific event and evidence supporting that decision.

Attached are my confirmation, boarding pass, cancellation notice, replacement itinerary, receipts, and prior correspondence.

Sincerely,
[name]
[contact information]

For a U.S. claim, remove the EU261 or UK261 request and refer instead to the DOT refund rule. For an EU or UK claim, include the distance, notice period, replacement-flight times, and final arrival delay.

How to challenge an airline denial

A denial should tell you what the airline decided, but it may not explain enough to test the decision. Ask four specific questions:

1. What exact event caused the cancellation?
2. Was the event within the airline's control?
3. What evidence supports the claimed exception?
4. How did the airline calculate the refund, compensation, or expense decision?

U.S. escalation

Start with a written complaint to the airline or ticket agent. Include the booking details, your refund request, and the documents that show the cancellation and payment. If an eligible refund still isn't provided, file a complaint with the U.S. Department of Transportation.

A DOT complaint can prompt a formal airline response and help the agency identify enforcement patterns. It isn't a private lawsuit and doesn't guarantee payment for inconvenience.

Airlines are generally required to acknowledge a written complaint within 30 days and provide a substantive written response within 60 days. The Travelers United explanation of the DOT complaint process describes what to include and how to submit the complaint.

EU and UK escalation

For an EU261 claim, follow up with the relevant national enforcement body, often the authority connected to the country where the flight departed. Alternative dispute resolution may be available, and court deadlines vary by country.

For a UK261 claim, check whether the airline belongs to an approved ADR scheme and follow the Citizens Advice guidance on delayed or canceled flights. The CAA can explain the applicable route, but an enforcement complaint may not recover money for you directly.

Send the airline's denial with your escalation, not just the original claim. Keep each attachment and record the date it was submitted.

Chargebacks: when they can help

A credit-card billing dispute can be a backup when an airline or ticket seller owes a refund for transportation that wasn't provided and refuses to pay. It isn't a substitute for an EU261 compensation claim, and a card issuer generally won't award the statutory EU261 amount.

Before contacting the issuer:

1. Ask the airline or ticket seller for the refund in writing.
2. Keep the cancellation notice, refund request, denial, and proof of payment.
3. Contact the card issuer promptly and ask where to send a billing dispute.
4. Describe the issue accurately as a service not provided or a refund not received. Don't report an authorized purchase as fraud.
5. Check the written-notice deadline. For many credit-card billing-error disputes covered by the Fair Credit Billing Act, the notice must reach the issuer within 60 days of the statement containing the charge. Use the billing-dispute address shown on the statement, if one is provided.
6. Tell the issuer about any later refund or credit so you don't recover the same amount twice.

Debit-card and prepaid-card protections differ from credit-card protections. Ask the bank about its network rules and deadlines instead of assuming the same process applies. A provisional credit can be reversed if the merchant successfully challenges the dispute.

If you cancel before the airline does

Choosing not to fly because you expect a disruption is different from an airline cancellation. If the flight operates as scheduled and you decide not to travel, the DOT automatic-refund rule usually won't apply.

Check the fare's cancellation terms, any airline travel waiver, and your travel-insurance policy. Standard trip-cancellation coverage usually requires a covered reason. Cancel For Any Reason coverage, when available and used within the policy's conditions, may reimburse only part of prepaid costs rather than the full amount. It can also have purchase deadlines, eligibility rules, and a higher premium.

Insurance may matter more for nonrefundable hotels, tours, or other expenses that the airline doesn't owe. Don't claim a loss that the airline has already refunded. Review exclusions for weather, civil unrest, and airspace closures before relying on the policy.

Common questions

Can I get a U.S. refund if the cancellation was caused by weather?

Usually, yes, for the unused ticket if the airline canceled the flight and you decline the alternative. Weather may affect meal, hotel, or compensation claims, but it generally doesn't eliminate the refund right.

Can I receive both an EU261 refund and compensation?

Potentially. EU261 reimbursement or rerouting and fixed compensation address different rights. Eligibility depends on the notice period, replacement-flight timing, route, operating carrier, and cause.

Does a U.S. airline have to pay for my hotel?

Not in every case under federal law. Ask about the airline's published commitments, keep receipts, and check travel insurance. EU261 may provide care while you wait for qualifying rerouting.

What if I booked through an online travel agency?

Send the written request to both the airline and the agency. Identify who charged your card and ask each party to confirm who is processing the refund. Keep both responses. The booking channel can affect the practical refund process even when the underlying passenger right is clear.

Save the cancellation notice and original itinerary first. Then send one written request that says exactly what you want: a refund, rerouting, fixed compensation, reimbursement of documented expenses, or a combination that the applicable rules allow.
