To claim compensation for a delayed flight, first identify which passenger-rights rules cover your journey. The airline, route, length of the delay at your final destination and reason for the disruption can all affect eligibility. A long wait by itself does not guarantee a payment: some rules provide fixed compensation only in specific circumstances, while others focus on refunds, assistance or losses you can document. Keep your booking confirmation, airline messages and receipts, then submit a clear claim to the airline responsible for operating the flight. The steps below help you assess your options and avoid confusing compensation with other forms of support.
There is no single worldwide rule that guarantees payment whenever a flight arrives late. Passenger rights depend mainly on where the flight departed, where it was going, which airline operated it and the cause of the disruption. The airline shown on your ticket may not be the operator: on a codeshare flight, look for the company that actually flew the aircraft.

| Rules to check | What commonly matters | What you may be able to request | Important limitation |
|---|---|---|---|
| EU passenger rights | Route coverage, arrival delay, disruption cause and the operating airline | In qualifying cases, fixed compensation, care during the wait or a refund if you choose not to travel | A delay alone does not establish eligibility; extraordinary circumstances may affect compensation. |
| UK passenger rights | Whether the journey falls within UK rules, plus delay, cause and operating airline | Potential compensation or assistance under the applicable rules | Route coverage and the amount can differ from EU arrangements. |
| United States | Airline commitments, the circumstances of the delay and whether the itinerary is cancelled or significantly changed | Possible help under the airline’s policies; a refund may be due if you reject a qualifying alternative after a cancellation or significant change | Federal rules do not generally require cash compensation simply because a flight is delayed. |
| Other countries or international claims | Local passenger-protection laws, the itinerary and, in some cases, documented loss | Possible statutory compensation, assistance, refund or recovery of proven losses | Rights and claim procedures vary; international carriage rules are not the same as automatic fixed compensation. |
For a broad route check, EU rules generally cover flights departing an EU airport, regardless of the airline, and certain flights arriving in the EU from outside it when operated by an EU airline. UK rules have their own route-coverage conditions. For either system, check the European Commission’s passenger-rights information or the UK Civil Aviation Authority guidance for your specific journey rather than assuming that a European destination automatically means the same rules apply.
Under EU rules, eligible passengers may receive fixed compensation when they reach their final destination at least three hours late, subject to the circumstances and route conditions. The standard amounts are €250, €400 or €600 per passenger, based on flight distance and route category; rerouting can affect the amount. UK compensation is governed by separate rules and may be expressed in pounds. Confirm the applicable amount and conditions for your trip before making a claim.
Start with the arrival time at the destination covered by your booking, not just the scheduled departure time. A flight that leaves late but makes up time in the air may produce a smaller arrival delay than expected. On a connecting itinerary booked as one journey, the relevant delay may be the time you reach the final destination; separate tickets can make the assessment more complicated because each flight may be treated as a separate booking.
The cause matters too. Under EU and UK compensation rules, airlines may not have to pay fixed compensation when an exceptional event outside their control caused the disruption and could not have been avoided despite reasonable measures. Severe weather or air-traffic restrictions may qualify, depending on the facts. An airline’s explanation is not automatically decisive: if it refuses your claim, ask what event caused the delay and how that event affected your flight.
Other rights can still apply even when fixed compensation is not payable. Depending on the rules and wait involved, an airline may have to provide practical assistance, such as meals or accommodation. If you decide not to travel after a lengthy delay, you may have a right to ticket reimbursement under applicable rules. These rights are separate from compensation for inconvenience, so ask about each one independently.

Make a folder for the booking and disruption, whether digital or printed. The airline may already have some operational records, but your own evidence makes it easier to explain what happened and to support expense claims.
For expenses, include the date, amount and reason for each cost. Keep spending reasonable and connected to the disruption; luxury purchases or unrelated costs may not be reimbursed. If the airline provided a meal, hotel or transport, record that too, since it may affect what additional expenses you can reasonably request.
Keep the first submission factual and easy to assess. Identify the passenger or passengers, provide the booking reference and flight details, state the arrival delay at the relevant destination, and explain what you are requesting. If you know the rule that applies, name it; if you are uncertain, ask the airline to assess the claim under the passenger-rights rules covering the route.
A short claim could read: “I am requesting compensation for the delay to booking [reference], flight [number] on [date]. We arrived at [final destination] at [time], which was [duration] after the scheduled arrival. Please assess our eligibility under the passenger-rights rules applicable to this journey. I have attached the booking confirmation and records of the disruption.” Add a separate list of any expenses for which you are seeking reimbursement.
Do not send original documents unless specifically required, and do not assume that an airline voucher is equivalent to a cash payment. Where a rule gives you a choice of payment method, read the terms before accepting a voucher or signing a settlement. Keep a record of any agreement you make with the airline.
Read the reason carefully. A rejection may say that the route is outside the relevant rules, the arrival delay was below the threshold, the airline considers the cause exceptional, or the claim was submitted too late. These are different issues and call for different next steps. If the explanation is vague, ask for the specific cause and the information the airline relied on.
If you still disagree, check the complaint route for the country whose rules apply. Depending on the route, that may involve a national aviation regulator, an approved alternative dispute-resolution service or a court. Their roles and powers are not identical, and some may not decide individual compensation claims. Check the process and any time limit before escalating.
Claims companies can handle paperwork, but they may charge a fee or take a share of a successful payment. Before signing, read the commission, cancellation and legal-action terms. You can usually begin by submitting a claim yourself, and you should not pay a company merely because it promises that a delay automatically qualifies.
If your route is not covered by a fixed-compensation system, check the airline’s own conditions of carriage and customer-service commitments. These may offer assistance or other remedies, but the terms can differ between airlines and are not necessarily the same as statutory compensation. In the United States, for example, the Department of Transportation distinguishes a delay from a cancellation or significant change: a refund may be required when a passenger declines a qualifying alternative, but a delay alone does not generally create a federal right to cash compensation.

For some international journeys, the Montreal Convention may provide a route to claim for loss caused by delay. This is not the same as automatic payment based on a delay threshold: the passenger generally needs to show a loss, and the carrier may have legal defences. If the amount involved is substantial or the airline disputes liability, consider getting advice on the rules and deadlines for the country concerned.
Travel insurance is another separate route. Check the policy’s delay, missed-connection and expense provisions, including what evidence it asks for and whether it excludes costs the airline has already paid. Notify the insurer within its stated time limits, and give accurate details of any airline reimbursement or compensation so the same expense is not claimed twice.
Possibly, but the answer depends on the rules covering your route. The three-hour arrival threshold applies to fixed compensation in eligible cases under EU rules; other jurisdictions and airline policies can use different tests or offer different remedies.
Usually, begin with the airline that operated the disrupted flight, especially for a codeshare booking. Include the ticket seller’s details if they help explain the itinerary, but check the applicable complaint process if the operating airline redirects you.
You may have a claim if the connection was part of one booking and the disruption caused a qualifying delay at your final destination. Separate tickets can be assessed differently, so keep both booking records and check the rules for each part of the journey.
Ask for the specific explanation and how the weather affected your flight. Weather can be an exceptional circumstance under some passenger-rights rules, but the airline’s statement alone does not resolve every question about the event or the steps taken to limit its effects.
There is no single deadline for every country or type of claim. Time limits can depend on the legal basis and where the case would be handled, so check the relevant regulator’s guidance and submit your claim as soon as you can.
Read the offer’s terms before accepting it, including any restrictions or settlement language. If the applicable rules give you a choice, make sure you understand whether accepting the voucher changes your right to request another form of payment.
To claim compensation for a delayed flight, match the route and operating airline to the right rules, establish the delay at the relevant destination and keep evidence of both the disruption and any costs. Then submit a precise request to the airline and follow the correct escalation route if its decision does not address your claim.
