What happens if my flight delay claim is rejected?

Having your flight delay claim rejected can feel like the end of the road — but it rarely is. Airlines reject claims for a range of reasons, and a significant number of those rejections are either wrong outright or based on grounds that can be successfully challenged. Getting a flight delay claim rejected does not mean you have no right to compensation. It means the airline has said no at the first stage, and you still have several options available to you.

This guide explains exactly what to do when a claim is turned down, how to challenge a rejection based on extraordinary circumstances, and how to escalate through the formal appeal process to get the result you are actually entitled to.

Why do airlines reject flight delay claims?

Before responding to a rejection, it helps to understand why it was issued. Airlines reject flight delay compensation claims for several reasons — some legitimate, some not.

The most common reason airlines give is extraordinary circumstances. Under UK 261 — the retained version of EU Regulation EC 261/2004 — airlines are not required to pay fixed compensation when the delay was caused by something genuinely outside their control. Severe weather, air traffic control strikes, airspace closures, and security emergencies are examples of situations that can qualify.

However, airlines sometimes claim extraordinary circumstances for situations that do not actually qualify. A technical fault discovered during pre-flight checks is not an extraordinary circumstance — it is part of normal airline operations. Staff shortages caused by internal scheduling are not extraordinary. Overbooking is never extraordinary. These are commercial decisions within the airline's control, and they do not exempt the airline from paying compensation.

Other common rejection grounds include claims that the flight was not covered by UK or EU regulation, that the delay did not meet the three-hour threshold, or that the claim was submitted too late. Each of these can and should be verified before accepting the airline's position.

Step 1: check whether your claim was actually valid

Before escalating, it is worth taking a moment to verify that your claim was well-founded. Pursuing a claim that does not meet the eligibility criteria wastes time and effort — and being clear on your position makes any appeal far stronger.

The key eligibility requirements for flight delay compensation under UK law are:

• Your flight departed from a UK or EU airport, or it arrived in the UK on a UK or EU carrier
• Your flight arrived at its destination more than three hours late compared to the scheduled arrival time
• The delay was caused by something within the airline's control — not an event qualifying as extraordinary circumstance
• The flight took place within the last six years (five years in Scotland)

The compensation amounts are fixed by law: £220 for flights up to 1,500km, £350 for flights between 1,500km and 3,500km, and £520 for flights over 3,500km. If you are unsure whether your specific route and delay length qualify, our flight compensation calculator gives you an instant answer based on your flight details.

Step 2: challenge the extraordinary circumstances defence

If the airline's rejection is based on extraordinary circumstances, this is the argument you need to examine most carefully — because it is also the one airlines misuse most frequently.

A genuine extraordinary circumstance must meet two tests: it must be something outside the airline's control, and it must be something the airline could not have avoided even with all reasonable measures taken. Both tests must be satisfied. An event that is outside the airline's control but that the airline could have prepared for — for instance, by having a reserve aircraft or additional crew on standby — may not qualify.

When extraordinary circumstances do not apply

Airlines commonly attempt to use extraordinary circumstances to avoid paying out in situations where it does not actually apply. If the airline cited any of the following as the reason for your delay or cancellation, the extraordinary circumstances defence is likely to fail:

• Technical or mechanical faults — these are part of routine aircraft maintenance and are considered within the airline's operational control in the vast majority of cases
• Crew shortages caused by rostering or scheduling failures — a predictable staffing issue is not extraordinary
• Late incoming aircraft from a previous flight — where the knock-on delay was foreseeable and the airline had time to take steps to manage it
• Overbooking — this is always a commercial decision made by the airline and can never qualify as extraordinary

If you believe the extraordinary circumstances cited by the airline do not genuinely apply, say so clearly in your response. Quote the regulation, state the reason you dispute the classification, and provide any evidence you have — photographs, news reports confirming the weather was not severe, or records showing the aircraft had a pre-existing maintenance issue.

When extraordinary circumstances are likely to apply

There are situations where an extraordinary circumstances rejection is likely to stand up to scrutiny. These include declared safety emergencies, extreme weather conditions that grounded multiple operators simultaneously, sudden airspace closures by air traffic control, natural disasters affecting the departure airport, or airport strikes by employees who do not work directly for the airline.

If the delay was genuinely caused by one of these factors and you cannot reasonably dispute it, your route is to escalate through the regulatory channels rather than challenge the extraordinary circumstances argument itself.

Step 3: submit a formal airline compensation appeal

If you believe your claim was wrongly rejected — whether because the extraordinary circumstances defence does not apply, because the airline has misidentified the cause of the delay, or for any other reason — your next step is to escalate formally within the airline.

Most airlines have an internal complaints procedure that must be used before you can take a claim to an external body. When submitting your airline compensation appeal, include the following:

1.     A clear statement that you are appealing the rejection of your compensation claim under UK 261 (or EU Regulation EC 261/2004 if the flight departed from an EU airport)

2.     The specific reason the airline gave for rejecting the claim, and your grounds for disputing it

3.     Evidence supporting your claim: your booking confirmation, boarding pass, and any documentation of the delay — screenshots of the departure board, correspondence from the airline, or records of your actual arrival time

4.     A reference to any information you have found that contradicts the airline's stated cause — for example, weather data showing conditions were not severe at the time of departure

5.     A clear statement of the compensation amount you are claiming and a reasonable deadline for the airline to respond — typically 14 to 28 days

Keep a complete record of your claim and all correspondence. This becomes important if you need to escalate further. If you are not confident about what your delay was worth or whether the initial flight delay claim process was handled correctly, our guide to understanding how long a flight delay claim takes explains the typical timeline at each stage and what affects it.

Step 4: escalate to an Alternative Dispute Resolution (ADR) scheme

If the airline rejects your appeal or fails to respond within a reasonable time, your next step is to take the claim to an Alternative Dispute Resolution scheme. ADR bodies are independent organisations approved to adjudicate disputes between passengers and airlines. Their decisions are generally binding on the airline — which means if the ADR rules in your favour, the airline must pay.

Whether you can use ADR depends on whether the airline is a member of an approved scheme. When an airline rejects a claim, it is required to tell you which ADR scheme it belongs to (if any). The main ADR schemes covering airlines operating in the UK include CEDR, Aviation ADR, and AviationADR.

Using an ADR scheme is free for passengers in most cases. You submit your complaint with supporting evidence, and the adjudicator reviews both sides of the case and issues a decision. This process typically takes up to 90 days. Be aware that some ADR schemes — such as CEDR, which covers British Airways — do charge a fee if your appeal is unsuccessful, so check the terms before submitting.

If the airline is not a member of any approved ADR scheme, you cannot use this route. In that case, you need to escalate directly to the Civil Aviation Authority.

Step 5: complain to the Civil Aviation Authority (CAA)

The Civil Aviation Authority is the UK's aviation regulator and operates a Passenger Advice and Complaints Team (PACT) that handles complaints about airlines that are not members of an ADR scheme. Unlike ADR, the CAA cannot issue legally binding decisions on individual claims — but it can assess whether your claim is valid, take the matter up with the airline on your behalf, and in serious cases, pursue regulatory action.

Submitting a complaint to the CAA is free. You will need to provide details of your flight, the airline's rejection, and any appeal response you have received. The CAA reviews the case and, where it believes a valid claim has been rejected unfairly, it will contact the airline. This can be effective in pressuring airlines that are rejecting legitimate claims at scale.

The CAA's official guidance on what to do when a claim is rejected includes step-by-step instructions on how to use its complaints process and explains which regulatory body handles which type of flight — including EU-based complaints that fall under member state regulators rather than the CAA.

Step 6: take the airline to the small claims court

If the ADR route is unavailable and the CAA has not resolved your complaint, or if you simply want to pursue the matter through a formal legal channel, you can take the airline to the small claims court. This is a relatively straightforward process for claims that are clear-cut and well evidenced, and it does not require a solicitor.

In England and Wales, claims for flight delay compensation up to £10,000 can be filed through the small claims track of the County Court. You submit your claim online, pay a small court fee (which is typically recovered if you win), and set out the facts of your case. The airline will be required to file a defence, and a hearing may be scheduled if the matter is not settled beforehand.

Many airlines settle quickly once a claim reaches the court stage, because the cost of defending a well-evidenced case often exceeds the compensation owed. If you decide to go down this route, make sure your paperwork is thorough: booking confirmation, boarding pass, delay records, the airline's rejection letters, and any evidence relating to the cause of the delay.

What you are still entitled to even if compensation is refused

It is important to understand that even when an airline successfully argues extraordinary circumstances — meaning the fixed compensation is not payable — your other rights as a passenger remain fully intact.

Regardless of why your flight was delayed or cancelled, if the delay was long enough, the airline was legally required to provide you with care while you waited: meals and refreshments, access to communications, and accommodation if you were stranded overnight. If the airline failed to provide these and you paid for them yourself, you are entitled to claim those reasonable expenses back.

You are also entitled to a full refund of your unused ticket if your flight was cancelled or delayed by more than five hours and you chose not to travel. This right applies regardless of the cause. Our guide to making a flight delay claim from the start covers the full picture of what you are owed at each stage of a disruption, including both compensation and care rights.

Common questions about rejected flight delay claims

Can I claim for a flight that was delayed more than six years ago?

No. UK law limits flight delay compensation claims to the last six years from the date of the flight (five years in Scotland). Claims outside this window cannot be pursued through any channel.

Does it cost anything to appeal a rejected claim?

Appealing directly to the airline is free. Using most ADR schemes is also free for passengers, though a small number charge a fee if the appeal is unsuccessful. Submitting a complaint to the CAA is free. Small claims court does involve a filing fee, but this is usually recovered if your claim succeeds.

What if I already accepted a voucher from the airline?

Accepting a voucher as a substitute for your ticket refund does not automatically waive your right to the fixed compensation under UK 261. Compensation and refunds are separate legal entitlements. However, if you signed a document explicitly releasing the airline from its compensation obligations in exchange for the voucher, you may have given up that right. Always read what you are signing before accepting any settlement from an airline.

Can I claim on behalf of other passengers on the same booking?

Yes. You can submit a single claim covering all passengers named on your booking. Each passenger is entitled to the same fixed compensation in their own right, so a family of four on a qualifying delayed flight would be entitled to the compensation amount multiplied by four.

Do not let a rejected claim be the end of the story

A flight delay claim rejected by an airline at the first stage is far from final. The law is clear about what passengers are owed, the appeal routes are well established, and a significant proportion of initial rejections are successfully overturned.

The most important thing is to act rather than accept the airline's decision without question. Check whether your claim was valid, assess whether the extraordinary circumstances defence actually holds up, and use the escalation routes available to you — ADR, the CAA, and the courts if necessary.
