How to Claim Flight Delay Compensation
Published 20 April 2026

Three hours late at the gate, a missed connection, and an airline app that tells you very little - that is usually when people start searching for how to claim flight delay compensation. The good news is that airline compensation rules are clearer than many carriers make them seem. The less good news is that claims are often delayed, rejected, or quietly ignored unless you send a precise, formal request backed by the right facts.
If your flight was delayed departing from the UK, arriving in the UK on a UK or EU airline, or otherwise covered by retained EC Regulation 261/2004, you may be entitled to compensation. That is separate from any refund, hotel stay, food vouchers, or reimbursement of extra costs. Compensation is about the inconvenience caused by a long delay, and in many cases you do not need a solicitor to ask for it.
How to claim flight delay compensation in the UK
Start with the basics. You will need your booking confirmation, flight number, travel date, and the actual arrival time. For compensation purposes, arrival time usually means when at least one aircraft door opens and passengers are allowed to leave, not when the wheels touched down.
You should also confirm whether the delay reached the legal threshold. In most cases, compensation is only payable if you arrived at your final destination more than three hours late. The amount depends mainly on the flight distance and, in some cases, the length of the delay.
For flights covered by the rules, the broad compensation bands are:
- £220 for flights up to 1,500km
- £350 for flights between 1,500km and 3,500km
- £520 for flights over 3,500km, although this can be reduced in some circumstances
These figures are the standard UK equivalents commonly used under the regulation. Airlines sometimes quote euro values or use slightly different wording, but the underlying entitlement is the same.
The next step is checking the reason for the delay. This matters because airlines do not usually have to pay compensation where the delay was caused by extraordinary circumstances. That phrase has a specific legal meaning. It does not just mean the airline had a difficult day.
Bad weather, air traffic control restrictions, airport security incidents, political instability, and some strike action outside the airline's control can count as extraordinary circumstances. Routine technical faults, crew shortages, and operational scheduling problems often do not. This is one of the most disputed parts of any claim, and it is where airlines regularly say no first and explain later.
When an airline must pay and when it may not
A delay alone is not enough. The claim usually depends on three things working together: your flight being covered by the regulation, your arrival delay being long enough, and the airline lacking a valid extraordinary circumstances defence.
That means two passengers on delayed flights can have different outcomes. If one flight was delayed by a mechanical fault discovered during normal operations, compensation may be due. If another was delayed because the airport shut during severe storms, it may not be. The detail matters.
It is also worth separating compensation from care obligations. Even where the airline does not owe compensation because of extraordinary circumstances, it may still have had a duty to provide assistance during the delay. Depending on the length of the wait and the route, that can include meals, refreshments, hotel accommodation, and transport between the airport and hotel. If the airline failed to provide that support and you paid out of pocket, keep receipts. You may be able to recover those costs even if compensation itself is not payable.
What evidence helps a flight delay claim
Airlines respond better to claims that look organised and specific. You do not need to send a bundle of paperwork for the sake of it, but you should keep enough evidence to show what happened.
Useful documents include your booking confirmation, boarding pass, delay notifications, screenshots from the airline app, and any message showing the stated reason for the delay. Photos of departure boards can help. If you had to pay for food, taxis, or a hotel because the airline did not provide assistance, keep the receipts.
If the flight involved a connection, make sure your claim refers to the final destination on the booking, not just the first leg. That can affect whether the three-hour threshold is met. Passengers sometimes undersell their own claim by only looking at the delay to the first stop.
How to write the claim properly
This is where many people lose momentum. They know they are owed something, but the airline's online form is vague, or the response asks for more information without really moving the claim forward. A formal written letter often puts the issue on firmer ground.
Your claim should identify the passenger, booking reference, flight number, date of travel, route, scheduled arrival time, actual arrival time, and the amount claimed. It should also state that the request is being made under retained EC Regulation 261/2004, explain why the delay qualifies, and give the airline a reasonable deadline to respond.
Keep the tone factual. There is no need to sound aggressive. A stronger approach is simply to be clear, accurate, and formal. If the airline has already rejected the claim, respond directly to the reason given. For example, if they blamed technical issues, you can state that ordinary technical faults are not generally treated as extraordinary circumstances under the regulation.
A posted letter can carry more weight than a complaint typed into a web form, especially where earlier contact has been ignored. For UK consumers who want a properly formatted claim without printing it themselves, a service like PostRight can help you send a legally grounded flight delay compensation letter quickly, with Royal Mail delivery options and no trip to the Post Office.
How long do airlines take to respond?
It varies. Some airlines deal with straightforward claims within a few weeks. Others drag the process out with stock replies, requests for duplicate documents, or broad references to extraordinary circumstances that are never properly explained.
That is why deadlines matter. In your letter, ask for a written response within a set period, such as 14 days. If the airline refuses the claim or fails to reply, you can escalate it. The right route depends on the airline. Some are members of an approved alternative dispute resolution scheme. Others may require a complaint to the Civil Aviation Authority for guidance before you consider court action.
If you do escalate, keep your paperwork consistent. The most persuasive claims are usually the ones that show a clear timeline: flight details, length of delay, evidence, original claim, and the airline's response or failure to respond.
Common reasons claims are rejected
Some rejections are valid. Many are not. Airlines often rely on broad wording, and passengers give up because the explanation sounds official.
One common issue is the airline saying the delay was due to extraordinary circumstances without giving enough detail. Another is confusion over arrival time, especially where a flight landed close to schedule but passengers were kept on board. There is also frequent muddle around connecting flights, rerouting, and whether the journey was booked as one contract or several separate tickets.
Technical faults are another grey area in practice, even if the legal position is often clearer than the airline suggests. Not every engineering issue leads to compensation, but ordinary wear and tear or operational maintenance problems do not automatically let the airline off the hook.
Claims also fail when passengers do not provide enough information. If your letter simply says your flight was late and you want compensation, it is easier for the airline to park it. A concise but detailed claim gives them less room to deflect.
A few practical points before you send your claim
Check the airline's legal name, not just its trading brand, and send the letter to the correct customer relations or legal correspondence address where possible. Make sure the claim is in the name of each affected passenger. A family booking does not always mean one person can claim for everyone without naming them.
Be careful with claims companies that take a large cut. They can be useful if your case is unusually complex or you simply do not want the hassle, but for many standard delays, the core task is getting a clear claim in front of the airline with the right legal basis and evidence.
It is also worth acting promptly. Limitation periods can be longer than people expect, but evidence gets harder to gather over time and airlines rarely become easier to deal with months later.
If you are wondering how to claim flight delay compensation, the answer is usually not complicated: confirm the flight is covered, check the delay length, assess whether extraordinary circumstances really apply, and send a formal claim that states exactly what you are owed and why. Once your letter is clear, specific, and properly sent, the conversation tends to become much more straightforward.
A delayed flight is irritating enough. Chasing compensation should not feel like a second journey.
