If an airline cancels a flight to, from, or within the United States, a nonrefundable fare usually isn't the end of the story. When the airline cancels the flight or makes a qualifying significant change, and you don't accept the alternative transportation, U.S. Department of Transportation rules generally require a refund for the unused transportation and services the airline didn't provide.

The refund should normally return to the original form of payment. The usual processing limits are seven business days for a credit-card purchase and 20 calendar days for other payment methods. Your card issuer may need additional time to post the credit.

That payment is a refund, not compensation for inconvenience. U.S. federal law generally doesn't require an airline to pay hotel, meal, or other disruption costs after every cancellation. The airline's customer-service policy, travel insurance, card benefits, or a separate passenger-rights system may produce a different result.

This checklist is focused on U.S. flights. EU261 and UK261 are separate systems with their own route and carrier tests.

The rule that controls the ticket refund

A nonrefundable label usually applies when you decide not to travel. It generally doesn't defeat a refund right created by the airline's cancellation or qualifying significant change.

For a U.S. ticket refund, the cause of the cancellation usually doesn't change the result. Weather, air-traffic restrictions, crew problems, and mechanical issues can all lead to a refund if you decline the alternative. The cause can still matter for meals, lodging, insurance, and any EU261 compensation claim.

What to do after the cancellation

1. Save the cancellation evidence

Keep the airline's email, text, app notice, booking record, and, if relevant, a photo of the airport display. Write down:

• Flight number, date, and route
• When you learned about the cancellation
• The stated reason, if the airline gave one
• Any replacement flight or voucher offered
• Names or identification numbers of staff who give you instructions
• Your confirmation number and ticket number

A verbal promise at the airport is hard to prove later. A written notice and a copy of your request give you a clearer record.

2. Choose before you use the replacement

An airline may automatically move you to another flight or place an eCredit in your account. That doesn't make the new option the same as a refund.

If you don't want to travel, say so in writing and ask for the original payment method. Don't board or complete the replacement flight while also expecting a refund for transportation you received. If you accepted another flight but used only part of the itinerary, explain exactly what you used and ask the airline to review the remaining segments and ancillary charges.

If reaching your destination matters more than getting the ticket price back, rebooking may be the practical choice. Ask the airline to show you both options and save your response.

3. Find the business that must handle the payment

Look at the receipt and card statement before deciding whom to contact.

• Bought directly from the airline: Start with the airline's website, app, or customer-relations team.
• Bought through an online travel agency or travel agent: Contact the seller that issued and charged the ticket. If it sends you back to the airline, keep that response and copy the airline where possible.
• Used a credit-card travel portal: Contact the portal and the airline, and keep both case numbers.
• Bought a package vacation: Notify the tour operator as well as the airline because package terms may apply.

The operating airline establishes that the flight was canceled. The seller or ticket agent may control the payment transaction and refund workflow.

4. Use the word "refund"

Don't submit a request that merely says "cancel my trip" or "give me a credit." State that the airline canceled the flight and that you're declining the alternative.

You can use this wording:

My reservation is [confirmation number]. [Airline] canceled flight [number] on [date]. I am declining the alternative transportation and requesting a refund to the original form of payment for the unused ticket, taxes, and fees for services not provided. Please confirm the refund amount, processing date, and reference number.

Don't describe an airline cancellation as a voluntary cancellation. If you already accepted a replacement, say that accurately and identify the portions you didn't use.

Ask for a written denial if the airline refuses. "Nonrefundable ticket" by itself may not answer a request based on an airline cancellation.

5. Check the add-ons

Include optional services you paid for but didn't receive, such as:

• A seat-selection fee for a seat you never used
• A checked-bag fee for a bag the airline never transported
• Priority or boarding fees tied to the canceled segment
• Other services listed on your receipt

Ask for an itemized calculation. The ticket fare and ancillary charges may appear as separate credits.

The ticket refund doesn't automatically cover a new ticket bought from another airline, lost wages, transportation to the airport, or other consequential costs. Keep those receipts anyway; an airline policy, insurance plan, or card benefit may address them.

6. Keep expense receipts, but ask before spending more

Save receipts for meals, hotels, ground transportation, replacement travel, and communication costs. Ask the airline whether its customer-service policy covers the expense before booking, particularly when the disruption was within the airline's control.

For a weather or air-traffic cancellation in the United States, federal law generally doesn't require the airline to pay for a hotel or meals. An airline may offer help voluntarily. Travel insurance and credit-card trip-interruption benefits may also help, subject to exclusions and claim deadlines.

If a checked bag was delayed or lost, file the airline's baggage report as soon as possible, preferably before leaving the airport. Keep the report number and handle that claim separately from the ticket-refund request.

7. Mark the refund deadline

For an eligible U.S. flight refund, the usual DOT processing limits are:

• Credit-card payment: seven business days
• Other payment methods: 20 calendar days

Those limits concern the airline's processing obligation. A card issuer or bank may take longer to post the money. If the airline says it issued the refund, request the processing date, amount, and refund trace or reference number.

The route, payment method, booking channel, and type of claim can affect the procedure. Keep the cancellation notice, request date, and every response until the credit appears.

8. Follow up with one complete record

When the deadline passes, send a short follow-up containing:

• The original refund request
• The cancellation notice
• Booking and ticket numbers
• The date you submitted the request
• Any response from the airline or ticket seller
• The amount you believe is due

Ask the company to explain its position in writing. A clear paper trail is more useful than repeated calls that leave you without a case number or transcript.

EU261 refunds and compensation

EU261 is a separate passenger-rights system, not an additional U.S. compensation rule. The departure airport and operating carrier matter more than the website where you bought the ticket.

EU261 may apply when:

• The flight departs from an airport in the European Union
• A flight arriving in the EU from outside the EU is operated by an EU carrier
• A connected European itinerary otherwise falls within the regulation's coverage

A U.S.-to-EU flight operated by an EU airline may be covered. The same route operated by a non-EU airline may not be covered by EU261. Flights departing the United Kingdom may instead fall under UK261, which is separate.

For an eligible cancellation, you generally choose one of these options:

1. Reimbursement of the ticket, usually within seven days
2. Rerouting to the destination as soon as possible
3. Rerouting at a later date that suits you, subject to availability

Fixed compensation may also be available when the airline gave less than 14 days' notice and the cancellation wasn't caused by extraordinary circumstances. The rerouting offered and the time it takes to reach the destination can remove compensation or reduce it.

The airline may reduce the compensation by 50% if the accepted rerouting arrives within the regulation's permitted time limits. No fixed compensation is generally due when the airline proves an extraordinary circumstance, such as severe weather or some external air-traffic-control or airport-worker strikes.

An airline's own staff strike isn't automatically an extraordinary circumstance. The circumstances and the reasonable steps taken by the carrier matter. While you wait for qualifying rerouting, EU261 may also require meals, refreshments, communications, and overnight accommodation when needed. Keep reasonable receipts.

The Your Europe air passenger rights FAQ covers the EU tests for cancellations, delays, strikes, and complaints.

Ryanair, Delta, and easyJet: where to begin

The airline's name doesn't determine the legal test. Start with the cancellation notice or account, then check the route, operating carrier, and seller.

Delta's published cancellation and refund instructions describe rebooking, eCredits, and refund requests for certain canceled or significantly disrupted trips. If a U.S. refund is due and you don't want the replacement flight, ask specifically for the original form of payment.

Ryanair, Delta, and easyJet don't share one refund timeline for every booking. Use the applicable U.S., EU261, or UK261 rule rather than relying on a generic estimate displayed by the carrier.

Weather, strikes, connections, and baggage

Weather and strikes

Weather generally doesn't remove the U.S. right to a ticket refund when the airline canceled the flight and you declined its alternative. It may affect whether the airline offers meals or lodging under its own policy.

Under EU261, severe weather and some external strikes may eliminate fixed compensation while leaving the reimbursement-or-rerouting choice intact. If the airline gives only a general "extraordinary circumstances" explanation, ask what specific event it relies on.

Connecting flights

If every leg is on one reservation and the airline cancels one segment, ask what happens to all remaining segments. If you decide not to continue, request reimbursement for the unused itinerary. A leg you already completed generally isn't refundable as unused transportation.

Separate tickets are different. The airline that canceled one ticket generally doesn't automatically owe a refund for a separately purchased onward ticket. Contact each seller promptly and check travel insurance for missed-connection coverage.

For an eligible EU261 itinerary, a missed connection on one reservation can support compensation when you arrive at the final destination at least three hours late and the delay wasn't caused by extraordinary circumstances. The United States has no comparable general federal compensation rule for ordinary delays.

Baggage and insurance

A baggage-fee request, delayed-baggage claim, and lost-baggage claim are separate from the flight-refund request. Attach the baggage report, bag tag, receipts, and delivery or loss details.

Notify a travel insurer or card-benefits administrator promptly. The policy may require proof that you first sought a refund or reimbursement from the airline, and it generally won't pay twice for the same loss.

If the airline denies the refund

1. Get the reason in writing. Ask for the exact reason, fare calculation, and rule or policy the company relied on.
2. Send one final written request. Attach the cancellation notice, receipt, and proof that you declined the alternative.
3. File a U.S. DOT complaint. Use the Air Travel Consumer Protection complaint form and include the airline's response, not only the original booking.
4. Ask the card issuer about a billing dispute. For a credit-card purchase, explain that the service was not provided. The issuer's deadline and evidence requirements control, and a chargeback isn't guaranteed. Debit and prepaid-card protections can differ.
5. Use the appropriate European route for an EU261 claim. Contact the National Enforcement Body for the country involved or the European Consumer Centre for cross-border consumer guidance.
6. Consider court only after documenting the dispute. Small-claims procedures, filing deadlines, and proper venue vary.

There is no universal 120-day chargeback rule for every airline purchase. Contact the issuer promptly if the airline fails to refund instead of waiting for a deadline quoted online.

Common questions

Do I get a refund when bad weather cancels my flight?

Usually, yes, for a U.S. flight that the airline canceled if you decline the replacement. Weather may affect hotel and meal assistance, insurance coverage, or EU261 compensation, but it generally doesn't erase the U.S. ticket-refund right.

Can the airline make me take a voucher?

When a refund is legally due, a voucher or eCredit is an alternative rather than a substitute you must accept. Ask for the original form of payment. Read the terms before accepting a credit because expiration and transfer rules vary.

Does a nonrefundable ticket qualify?

Usually, if the airline canceled the flight or made a qualifying significant change and you didn't accept the alternative. The nonrefundable label is mainly relevant when you cancel voluntarily.

Will the airline pay for my hotel?

Not automatically under general U.S. law. The airline's policy, the cause of the disruption, EU261 or UK261 coverage, insurance, and card benefits may change the answer. Ask about coverage before booking and keep the receipt.

What if the airline rebooked me automatically?

If you haven't used the new flight, tell the airline in writing that you decline it and want a refund. If you flew the replacement, ask instead about unused segments, unprovided services, compensation, or expense reimbursement. Don't request a refund for transportation you received.

Start by saving the cancellation notice and sending a written refund request. Then calendar seven business days for a credit-card purchase or 20 calendar days for another payment method, and keep the complete record until the money posts.
