The short answer

A delayed flight doesn't have one universal payout. For a flight governed only by U.S. rules, a late arrival generally does not create a federal right to cash compensation. The operating carrier's contract, customer-service commitments, travel insurance, or credit-card benefits may still provide rebooking, care, or expense reimbursement.

EU261 and UK261 work differently. Depending on the departure airport and operating carrier, arriving at your final destination three hours or more late can lead to fixed compensation of up to €600 or £520, unless an extraordinary circumstance applies. The maximum amount isn't automatic: distance, arrival delay, rerouting, and the cause of the disruption all matter.

A refund is a separate remedy. Under U.S. rules, a cancellation or qualifying significant change may entitle you to a ticket refund if you reject the alternative transportation. In the EU and UK, a departure delay of at least five hours can also give you a right to reimbursement if you decide not to travel.

Quick rule

• Save your booking, boarding pass, delay notices, screenshots, and receipts.
• Identify the operating carrier and the jurisdiction before filing.
• For EU and UK compensation, measure delay at your final destination, not only at departure.
• For U.S. flights, check the airline's contract and customer-service commitments instead of assuming a fixed payout.
• Keep compensation, ticket refunds, expense reimbursement, insurance, and credit-card disputes as separate claims.

Compensation, refunds, and expenses are different claims

One disruption can support more than one remedy. For example, an EU or UK passenger may be able to request fixed compensation and reasonable care expenses. A full ticket refund is different from compensation and generally won't be available after you complete the replacement journey.

Read any voucher or settlement language before accepting it. It may affect other claims, depending on what you agree to.

EU and UK flight delay compensation rules

When the rules apply

EU261 generally covers:

• A flight departing from an EU airport, regardless of the airline.
• A flight arriving in the EU from outside the EU when operated by an EU carrier.
• Some routes involving the EEA and Switzerland through related passenger-rights arrangements.

UK261 generally covers flights departing a UK airport and certain flights arriving in the UK from outside the UK when operated by a UK carrier. The route and operating carrier matter more than your nationality or where you bought the ticket.

For example, a flight from Paris to New York is generally covered by EU rules even if a non-EU airline operates it. A flight from New York to Paris on a U.S. airline usually isn't covered by EU261 merely because it lands in France. The same arrival on an EU airline may be covered.

Codeshares can make the correct respondent unclear. A fixed-compensation claim normally goes to the airline that operated the affected flight, not automatically to the travel website or booking agent. The seller may still need to handle a refund or booking error.

Standard compensation amounts

These amounts apply per eligible passenger. The usual qualifying delay is three hours or more at the final destination, and the airline must not be able to rely on an extraordinary circumstance. Depending on the rerouting and the resulting arrival time, the airline may reduce the standard amount by 50 percent.

For a connection on one booking, measure the delay when you reach the final destination shown on that booking. Separate tickets are usually assessed separately. The relevant arrival time is generally when at least one aircraft door opens, rather than when the plane touches down.

Meals, hotels, and refunds

EU and UK rules can also provide a right to care during a significant wait. Depending on the flight distance, the airline should generally offer reasonable food and refreshments after two, three, or four hours, along with a way to communicate. If an overnight stay becomes necessary, hotel accommodation and transport between the airport and hotel may also be required.

If the airline doesn't provide care, buy only reasonable necessities and keep itemized receipts. Premium meals, alcohol, luxury hotels, and unrelated purchases are less likely to be reimbursed. These expenses should be listed separately from fixed compensation.

If the departure delay reaches at least five hours and you decide the trip no longer serves its purpose, ask for reimbursement of the unused journey before arranging an expensive replacement. A refund and rerouting are different choices, so don't accept one without understanding what happens to the other.

Challenging an extraordinary-circumstances denial

Severe weather, air-traffic-control decisions, airport closures, and security events may qualify as extraordinary circumstances. The label alone isn't enough. Ask the airline to identify the event, explain how it caused the delay, and describe the reasonable steps it took to avoid or reduce the disruption.

An airline's own staffing strike or a routine technical problem isn't automatically an extraordinary circumstance. Case law distinguishes events within normal airline operations from events genuinely outside the carrier's control. Ask for a specific explanation instead of accepting a generic message that says only "weather" or "operational reasons."

Even when an extraordinary circumstance removes fixed compensation, the separate right to care may still apply.

U.S. flight delays: what you can claim

U.S. law doesn't generally set a fixed cash payment for an ordinary delayed arrival. The airline's contract of carriage and customer-service commitments usually determine whether it offers rebooking, meal vouchers, hotel rooms, transportation, or a goodwill payment. One carrier may offer a hotel for a controllable overnight delay while another may offer only rebooking.

A ticket refund is a separate issue. Department of Transportation refund rules address cancellations and significant itinerary changes. If the airline makes a qualifying change and you don't accept the alternative transportation, you may be entitled to a refund rather than a voucher. If you take the replacement flight, a full refund for the same journey generally won't be available.

For the federal framework, review the Federal Register notice on airline refunds and other consumer protections. The DOT Airline Customer Service Dashboard shows the carrier's stated commitments. A customer-service promise isn't the same as an EU-style statutory compensation schedule.

Travel insurance and credit-card trip-delay benefits are separate contracts. They may reimburse qualifying, documented expenses after a required waiting period, but coverage depends on the policy, the cause of the delay, and the payment method. Don't submit the same expense to two providers without disclosing the other claim.

How to file a flight delay claim

1. Identify the rule and airline that control

Write down:

• The operating carrier for every affected segment.
• The flight numbers, dates, airports, and scheduled times.
• Whether all segments were on one reservation.
• Your scheduled and actual final destination.
• Whether the trip departed from or arrived in a place covered by EU261 or UK261.
• For a U.S. flight, the airline policy or refund rule you intend to use.

The company that sold the ticket may still need to handle a refund or booking error, but the operating carrier is usually the starting point for a delay claim.

2. Build a precise timeline

Record the scheduled departure and arrival, the time the delay was announced, each revised estimate, and the actual arrival. Save airline emails, text messages, app alerts, and photographs of airport information screens.

For an EU or UK compensation claim, try to establish when the aircraft door opened at the final destination. A flight-tracking app can help corroborate your timeline, but it isn't always definitive. If the airline disputes the arrival time, ask it to identify the time record it used.

If you missed a connection, keep evidence for both flights and show that they were on one booking. If the plane diverted, record the original airport, the diversion airport, transportation offered, and the time you reached the booked final destination.

3. Request care before paying out of pocket

At the airport, ask the carrier for the meal, hotel, transport, or communication assistance that may apply. If staff tell you to arrange your own hotel or food, ask for that instruction in writing or save the airline message.

Keep receipts even if the airline refuses help. Spend reasonably, and avoid booking a luxury room or costly alternative transport without confirmation. In the U.S., ask which policy covers the expense. If the airline offers a voucher, check whether accepting it releases any other claim.

Don't abandon a flight or buy a replacement ticket until you've decided whether you want a refund or rerouting. If the airline instructs you to purchase a replacement, preserve that instruction.

4. Gather supporting evidence

A strong file normally includes:

• Booking confirmation, ticket number, and booking reference.
• Boarding passes for every passenger and affected segment.
• The operating carrier's name.
• Screenshots or photographs showing delay or cancellation information.
• Airline emails, text messages, and chat transcripts.
• A written timeline of announcements and staff explanations.
• Itemized receipts for meals, hotel, transport, and other necessary costs.
• Proof of payment for claimed expenses.
• Evidence of the replacement flight or rerouting, if applicable.
• The airline's denial and any explanation of extraordinary circumstances.

Send copies, not irreplaceable originals. Remove unnecessary payment information, and never email a full card number or banking password.

5. Calculate the claim before submitting it

For an EU or UK claim, use the applicable distance band and the delay at the final destination. Then list care expenses separately. Don't inflate the delay by counting time spent waiting at the gate if the final arrival was under three hours.

For a U.S. claim, quote the exact policy language or request a refund under the applicable DOT rule. Separate:

1. Ticket refund.
2. Reimbursement of promised or policy-covered expenses.
3. Travel-insurance or card-benefit expenses.
4. Any discretionary goodwill request.

If you're asking for a refund after a significant change, state accurately whether you rejected the alternative and whether you traveled. A precise claim is easier to review than a demand for a large, unexplained amount.

6. File with the airline in writing

Use the airline's official claim form when one exists. If the form doesn't allow all details, send a written follow-up through the airline's verified customer-service channel. Include the booking reference, passenger names, flight details, scheduled and actual times, the remedy requested, the amount, and an evidence list.

Keep the confirmation number and a copy of every attachment. Don't rely on a phone call alone. If the airline rejects the claim, ask it to state the operating cause and identify the rule or policy it used.

Copy-and-edit claim template

Subject: Flight delay claim - [flight number], [date], [booking reference]

Dear [airline],

I was booked on [flight number] from [origin] to [final destination] on [date]. The scheduled arrival was [time and time zone], and the actual arrival was [time and time zone]. For an EU or UK claim, the aircraft door opened at approximately [time].

The itinerary was booked under [booking reference] and included [number] passenger or passengers.

I am requesting the remedies that apply to these facts:

• Fixed compensation of [€250, €400, €600, £220, £350, or £520] under [EU261 or UK261]; or
• A cash refund because [the flight was cancelled or significantly changed and I did not accept the alternative]; or
• A cash refund because [the EU or UK departure delay reached at least five hours and I chose not to travel]; and
• Reimbursement of these documented expenses: [brief list and amounts].

Please identify the operating cause of the disruption and explain the rule or policy you believe applies. If you deny the request, please provide the reason in writing and identify the evidence supporting that decision.

Attached are [booking confirmation, boarding passes, delay records, airline messages, receipts, and other evidence].

Please confirm receipt and provide your decision through [email or secure claims channel].

Sincerely,
[full name]
[email and phone number]

Delete any option that doesn't match what happened. Compensation and reasonable care expenses may be requested together where applicable, but don't say you rejected a voucher or alternative flight if you accepted it.

What to do after a denial

Read the denial for its actual reason. Common explanations include:

• The arrival delay was below the applicable threshold.
• The airline says the event was extraordinary.
• The claim was sent to the wrong carrier.
• The airline says the evidence doesn't establish the final arrival time.
• The airline treats the request as a refund when you requested compensation, or the reverse.

Send one focused reconsideration with any missing evidence. If the airline cites weather, an airport restriction, or a strike, ask for the specific event, the time it affected the flight, and the measures taken to reduce the delay. Avoid relying on a generic flight-tracker screenshot alone.

Escalation depends on the jurisdiction:

• UK: Write to the airline first. The CAA guidance on making an airline complaint says that if you receive no response within eight weeks or are dissatisfied with the response, you may be able to use an approved alternative dispute-resolution scheme. Where no ADR scheme is available, the CAA's PACT route may be relevant.
• EU: Check the national enforcement body or ADR route for the country connected to the flight. That body may explain compliance but may not recover an individual payment, so court action may be a separate option. Citizens Advice guidance on delayed and cancelled flights also outlines complaint routes for UK consumers.
• U.S.: After giving the airline a reasonable opportunity to respond, submit a complaint through the Department of Transportation's consumer-protection process if the issue concerns a federal rule or a promised airline practice. A DOT complaint isn't the same as a private compensation award. For a contract claim or small-claims case, check the correct legal name of the operating carrier, the court's jurisdiction, and the applicable filing deadline.

A credit-card billing dispute isn't a substitute for flight-delay compensation. Contact the card issuer only when the facts fit its dispute rules, such as a qualifying refund that wasn't provided or a service that was paid for but not delivered. Issuer deadlines can be short.

You can also use a flight-claims company, but compare its fee, court-cost treatment, and settlement authority before signing. No advertised success rate guarantees payment in your case.

Deadlines and common mistakes

There is no universal two-year, three-year, or six-year deadline for every flight-delay claim. EU and UK limitation periods can vary by country, and U.S. deadlines can depend on state law, the ticket contract, and the type of claim. An airline's request to submit receipts within a certain period may also differ from the legal deadline for court action.

File promptly, preserve the original records, and check the limitation period for the jurisdiction connected to your claim. Don't assume that waiting for an airline response extends the legal deadline.

Avoid these mistakes:

• Claiming from the booking website when the operating airline handles the delay issue.
• Using departure delay instead of final arrival delay for EU or UK compensation.
• Treating a flight-tracker estimate as the only proof.
• Accepting a voucher or signing a settlement without reading its effect.
• Claiming unreasonable meals, hotels, or transport.
• Treating a generic "weather" message as conclusive proof.
• Asking for a full ticket refund after taking and completing the replacement journey.
• Mixing an insurance claim, airline claim, and card dispute without tracking duplicate expenses.
• Sending sensitive bank or card details through an unverified link.
• Missing a country-specific limitation period while waiting for customer service.

Before you submit

Put the scheduled arrival, actual arrival, operating carrier, stated cause, remedy requested, amount, and evidence list on one page. Submit that file through the airline's verified claims channel and save the confirmation number. Use the same record if you later contact the airline, regulator, ADR provider, insurer, or card issuer.
