Flight Delay Compensation UK261: How Much You Can Claim

If your flight arrives 3 or more hours late, retained EU Regulation 261/2004 ("UK261"), enforced by the CAA, may entitle you to fixed compensation of £220 to £520. You claim directly from the airline, for free; you never need to pay a claims firm a cut.

What UK261 Covers

UK261 is the retained version of EU Regulation 261/2004, kept in UK law after Brexit and enforced in the UK by the Civil Aviation Authority (CAA). It applies to a flight departing from a UK airport, on any airline, and to a flight arriving in the UK, but only if that flight is operated by a UK or EU airline. It also covers a flight from outside the UK to an EU airport if a UK airline operates it. For both kinds of flight departing outside the UK, UK261 does not apply if you already received compensation and assistance under the rules of the country you departed from. A flight arriving in the UK on a non-UK, non-EU airline, having departed from outside the UK, generally falls outside UK261. The rules cover long delays, cancellations and denied boarding, and they exist alongside, not instead of, your right to be looked after during a delay.

Compensation for a Delayed Flight

Compensation depends on how late you actually arrive at your final destination and how far you were flying, not on how late the flight departed. The 3-hour threshold is measured against your scheduled arrival time.

The UK flight delay compensation checker checks whether your delayed flight is covered by the UK rules and how much compensation they give, £220, £350, £260 or £520 per passenger, and how to claim directly for free.

Long-haul flights (over 3,500km) are split into two separate sub-tiers rather than a single flat figure: a delay of 3 to 4 hours pays £260, and only a delay of 4 hours or more pays the higher £520. Distance is measured using the great circle method between the departure and final destination airports.

The Airline's Duty of Care

Separately from compensation, the airline owes you a duty of care the moment a delay passes a shorter threshold, roughly 2 hours for shorter flights, 3 hours for medium-length flights, and 4 hours for long-haul flights. This duty applies regardless of what caused the delay, including extraordinary circumstances that would remove your right to compensation. It covers reasonable food and drink, a way to make two phone calls or send two emails, and, if you are delayed overnight, hotel accommodation plus transport between the airport and the hotel. If the airline fails to provide this and you pay for it yourself, keep receipts, since you can generally claim reasonable costs back.

Extraordinary Circumstances

An airline does not have to pay compensation if it can show the delay or cancellation was caused by "extraordinary circumstances" it could not have avoided even if it had taken all reasonable measures. Examples include severe weather, security risks, strikes affecting air traffic control or airport staff, and hidden manufacturing defects discovered in an aircraft's structure. Extraordinary circumstances remove only the compensation duty, never the care duty described above. A routine technical or mechanical fault with the aircraft is generally treated as within the airline's normal operational risk, so it is usually NOT extraordinary circumstances, and compensation can still be due even though the airline may argue otherwise.

Cancellations and Denied Boarding

If your flight is cancelled, you have the choice of a full refund of the unused part of your ticket or being rerouted to your destination. Compensation for a cancellation can also be due, calculated the same way as for a delay, unless the airline gave you enough advance notice of the cancellation or it falls within extraordinary circumstances. If you are denied boarding on a flight you have a valid booking for, typically because it was overbooked, you are entitled to compensation using the same distance bands, plus a choice of refund or rerouting, unless you volunteered to give up your seat in exchange for the airline's own offered benefits. In both cases, if the airline reroutes you and you arrive no more than 2 hours (flights up to 1,500km), 3 hours (1,500 to 3,500km) or 4 hours (longer flights) after your original scheduled arrival, it can reduce the compensation by half.

How to Claim Compensation Yourself, for Free

You do not need a claims management company to claim UK261 compensation. The process is:

1. Write to the airline first. Use its official complaints channel, state your flight number, date, the delay length, and the compensation band you believe applies, and ask for payment within a reasonable time.
2. Wait for its final response, or 8 weeks if it does not reply, before escalating.
3. Escalate to the airline's ADR scheme. Most UK airlines are signed up to an alternative dispute resolution (ADR) provider that can decide the dispute; the airline must tell you which one covers it.
4. Contact the CAA if the airline is not signed up to an ADR scheme. The CAA's Passenger Advice and Complaints Team may be able to take up your complaint with the airline, but it is only likely to consider it where the airline is not a member of an approved ADR body.
5. If none of that resolves it, the small claims court is the backstop for the amount involved.

None of these steps cost anything beyond your own time, and you keep 100% of any compensation awarded.

Why to Think Twice Before Using a Claims Management Company

Claims management companies advertise heavily around flight delays, but they are not doing anything you cannot do yourself for free: writing to the airline and, if needed, escalating to ADR or the CAA. In exchange, a claims firm typically takes a percentage of whatever compensation is awarded, sometimes a substantial one, out of money that would otherwise be entirely yours. Before using one, weigh whether you are simply paying for someone to send a letter you could send yourself at no cost. If you do use one, claims management activity is regulated by the Financial Conduct Authority (FCA), so check the firm is FCA-authorised and read its fee terms carefully before signing anything.

Related UK Consumer Rights

Flight delays sit alongside other travel and payment protections. If you booked a flight as part of a package holiday, see package holiday rights for the separate 14-day refund and ATOL protection rules. If an airline will not resolve your complaint, the general escalation steps in how to complain about a company apply. If you paid for the flight or holiday on a credit card, Section 75 can offer a separate route against the card issuer for breach of contract.

Frequently Asked Questions

How late does my flight need to be for compensation under UK261?

You need to arrive at your final destination 3 or more hours later than scheduled. Compensation is based on your actual arrival time, not how late the flight departed.

How much compensation can I get for a delayed flight?

It depends on distance: £220 for flights up to 1,500km, £350 for 1,500 to 3,500km, and for flights over 3,500km, £260 if you are 3 to 4 hours late or £520 if you are 4 or more hours late.

Does UK261 cover every flight I take?

It covers flights departing a UK airport on any airline, flights arriving in the UK, but only if operated by a UK or EU airline, and flights from outside the UK into the EU operated by a UK airline. A flight arriving in the UK on a non-UK, non-EU airline from outside the UK generally falls outside UK261.

What counts as extraordinary circumstances that remove compensation?

Things like severe weather, security risks, strikes affecting air traffic control or airport staff, and hidden manufacturing defects. A routine technical or mechanical fault with the aircraft is generally NOT treated as extraordinary circumstances.

Do I still get looked after if the delay is due to extraordinary circumstances?

Yes. The airline's duty of care, food, drink, communication and, if needed, overnight accommodation, applies regardless of the cause of the delay. Only the compensation duty can be removed by extraordinary circumstances.

Do I need a claims management company to get my compensation?

No. You can claim directly from the airline for free, then escalate to its ADR scheme or the CAA if it does not pay. A claims management company will typically take a percentage of your compensation for doing the same steps you can do yourself.

What if the airline refuses to pay or does not respond?

Escalate to the airline's ADR scheme once it gives its final response or after 8 weeks without one. If it is not signed up to an ADR scheme, contact the CAA's Passenger Advice and Complaints Team, or use the small claims court as a last resort.

Am I entitled to anything if my flight is cancelled instead of delayed?

Yes. You can choose a full refund of the unused ticket or rerouting to your destination, and compensation can also be due on the same distance bands, unless you had enough advance notice of the cancellation or it falls within extraordinary circumstances. If the airline reroutes you and you arrive only a little late (within 2, 3 or 4 hours of the original arrival time, depending on distance), it can halve the compensation.
