Flight Delay Compensation UK: Your Complete Guide to Claiming

If your flight has been delayed by 3 hours or more, cancelled, or you have been denied boarding, you could be entitled to compensation of up to £520 per person. Under UK law, airlines must pay out, and the rules are firmly in your favour. Yet millions of eligible passengers never claim because they do not know their rights or assume the process is too complicated.

This guide explains everything you need to know about claiming flight delay compensation in the UK in 2026, including the exact regulations, how much you are owed, and how to make a successful claim.

What Is UK261 and How Does It Protect You?

UK261 is the retained EU regulation (formerly EC 261/2004) that was carried into UK law after Brexit. It sets out clear rules on what airlines owe passengers when things go wrong. The regulation applies to all flights departing from a UK airport regardless of the airline, and to flights arriving at a UK airport if operated by a UK or EU carrier.

Under UK261, you are entitled to compensation if your flight arrives at its final destination more than 3 hours late, your flight is cancelled less than 14 days before departure, or you are denied boarding due to overbooking. The compensation is a fixed amount based on the distance of your flight, not the price of your ticket. This means a passenger who paid £30 for a budget flight has exactly the same rights as someone who paid £300 for a premium seat.

How Much Compensation Can You Claim?

The compensation amounts under UK261 are fixed and straightforward:

Short-Haul Flights (up to 1,500 km): £220

This covers most flights within the UK and to nearby European destinations such as Dublin, Amsterdam, Paris, and Brussels. If your London to Edinburgh flight was delayed by 3 hours, you are owed £220 per passenger.

Medium-Haul Flights (1,500 km to 3,500 km): £350

This covers most European destinations including flights to Spain, Greece, Turkey, and the Canary Islands. A delayed flight from Manchester to Tenerife would entitle you to £350 per person.

Long-Haul Flights (over 3,500 km): £520

This covers flights to the Americas, Asia, Africa, and Australasia. If your flight from Heathrow to New York arrived more than 3 hours late, each passenger on the booking is owed £520.

These amounts are per passenger, not per booking. A family of four on a delayed long-haul flight could claim £2,080. Children, including infants with their own seat, are entitled to the same compensation as adults.

The 3-Hour Rule Explained

Compensation is triggered when your flight arrives at its final destination 3 or more hours late. The arrival time is measured by when the aircraft doors open at the gate, not when the plane touches down on the runway. This distinction matters because taxiing and waiting for a gate can add 15 to 30 minutes.

For delays of exactly 3 hours, you are entitled to the full amount. There is no sliding scale. Whether your flight was 3 hours late or 12 hours late, the compensation amount is the same (though longer delays may give rise to additional claims for expenses).

For long-haul flights delayed between 3 and 4 hours, the airline may reduce the compensation by 50%, bringing it to £260. For short and medium-haul flights, there is no reduction.

Which Flights Are Covered?

UK261 covers two categories of flights. First, any flight departing from a UK airport, regardless of the airline. This means budget carriers, charter airlines, and foreign airlines are all covered when flying out of the UK. Second, flights arriving at a UK airport, but only if operated by a UK or EU carrier. So a British Airways or Ryanair flight from New York to London is covered, but an American Airlines flight on the same route would not be covered under UK261 (though it may be covered under US regulations).

Connecting flights add a layer of complexity. If your journey involves a connection and you booked it as a single ticket, the delay is measured at your final destination. If you booked separate tickets for each leg, each flight is assessed independently.

Extraordinary Circumstances: When Airlines Do Not Have to Pay

Airlines can refuse compensation if the delay was caused by "extraordinary circumstances" that were genuinely beyond their control. However, this defence is much narrower than airlines would like you to believe. Courts have consistently ruled against airlines that try to use this excuse too broadly.

Valid Extraordinary Circumstances (airline does not have to pay):

Severe weather that makes flying genuinely unsafe (not just rain or moderate winds), air traffic control restrictions imposed by authorities, security threats or airport closures ordered by authorities, political instability or natural disasters, and bird strikes (in most cases).

Not Extraordinary Circumstances (airline must pay):

Technical faults or mechanical problems with the aircraft (the Supreme Court confirmed this in 2014), staff shortages including pilot or crew sickness, airline IT system failures, fuelling issues, baggage loading delays, and delays caused by the late arrival of the inbound aircraft (unless that delay was itself caused by extraordinary circumstances).

If an airline tells you the delay was due to "operational reasons" or a "technical issue," this is almost certainly not an extraordinary circumstance, and you should press your claim.

How Long Do You Have to Claim?

In England, Wales, and Northern Ireland, you have 6 years from the date of the flight to make a claim. In Scotland, the limitation period is 5 years. This means you can claim for flights going back to 2020 or 2021 right now. Many passengers do not realise this and assume they can only claim for recent flights.

If you use Paybacker's email scanning feature, it can identify flight booking confirmations in your inbox and flag any that may be eligible for delay compensation. This is particularly useful for finding older flights you may have forgotten about.

Step-by-Step: How to Claim Flight Delay Compensation

Step 1: Check Your Eligibility

Confirm that your flight meets the criteria: departed from a UK airport (or arrived at one on a UK/EU carrier), was delayed by 3+ hours at the final destination, and occurred within the last 6 years (5 in Scotland). You can check flight delay records on sites like FlightAware or Flightstats to verify the actual arrival time.

Step 2: Gather Your Evidence

You will need your booking confirmation or e-ticket, your boarding pass (if you still have it), evidence of the delay (airline communications, screenshots of departure boards, FlightAware data), and receipts for any expenses incurred during the delay (meals, drinks, transport, accommodation). If you no longer have your booking confirmation, your bank statement showing the payment to the airline is usually sufficient.

Step 3: Write to the Airline

Contact the airline's customer service or complaints department directly. Your letter or email should include your full name and contact details, booking reference and flight number, the date of the flight, departure and arrival airports, the scheduled and actual arrival times, a clear statement that you are claiming compensation under UK261, and the amount you are claiming based on the flight distance.

Step 4: Wait for a Response

Airlines must respond to your complaint. Many will try to reject your claim initially, often citing extraordinary circumstances or offering vouchers instead of cash. You are entitled to cash compensation, not vouchers, and you do not have to accept a voucher offer. If the airline rejects your claim and you believe the rejection is unjustified, move to the next step.

Step 5: Escalate to an ADR Scheme or the CAA

Most UK airlines are members of an Alternative Dispute Resolution (ADR) scheme, either CEDR or AviationADR. These are free services that review your claim independently. If the airline is not part of an ADR scheme, you can complain to the Civil Aviation Authority (CAA), which can investigate on your behalf. As a final option, you can take the airline to the small claims court for claims up to £10,000. The filing fee is modest (typically £35 to £120), and you do not need a solicitor.

What Else Are You Entitled To During a Delay?

Beyond compensation, UK261 requires airlines to provide care and assistance during long delays, regardless of the cause (even extraordinary circumstances). For delays of 2 hours or more on short-haul flights (3 hours for medium-haul, 4 hours for long-haul), the airline must provide reasonable meals and refreshments, two free phone calls or emails, and if an overnight stay is required, hotel accommodation and transport to and from the hotel.

If the airline does not provide these, keep your receipts for any reasonable expenses and claim them back separately from your compensation claim. "Reasonable" means standard meals and a standard hotel, not champagne and a five-star suite.

Common Airline Tactics to Avoid Paying

Airlines are businesses, and many have developed tactics to discourage or reject valid claims. Here are the most common ones to watch for.

Offering vouchers instead of cash is the most frequent tactic. You have the right to cash compensation and do not need to accept vouchers. Blaming "technical issues" and calling them extraordinary circumstances is another common approach, but courts have consistently ruled that technical problems are within the airline's control. Some airlines simply ignore claims hoping you will give up. If they do not respond within 8 weeks, escalate immediately. Others will lowball the amount, offering less than the statutory amount. Check the distance of your flight and ensure you are claiming the correct figure.

Claiming for Package Holidays

If you booked a package holiday through a tour operator, you can still claim flight delay compensation under UK261. Your claim should be directed at the airline that operated the flight, not the tour operator. However, if the delay caused you to miss part of your holiday (for example, losing a day of your hotel booking), you may also have a separate claim against the tour operator under the Package Travel Regulations 2018.

Multiple Claims From One Journey

Every passenger on a booking can claim individually. If you booked flights for your family, each person (including children) is entitled to compensation. For a family of four on a delayed medium-haul flight, that is £1,400 in total. You can submit all claims together in a single letter, but make sure to list each passenger's name and details.

Frequently Asked Questions

Can I claim flight delay compensation if my flight was years ago?

Yes. In England, Wales, and Northern Ireland you have 6 years to claim. In Scotland you have 5 years. This means you can claim for eligible flights going back to 2020 or 2021.

How much flight delay compensation can I get?

Compensation under UK261 is based on flight distance: £220 for short-haul flights (up to 1,500 km), £350 for medium-haul flights (1,500 to 3,500 km), and £520 for long-haul flights (over 3,500 km). These amounts are per passenger, not per booking.

Do I have to accept vouchers instead of cash for flight delay compensation?

No. Under UK261, you are entitled to cash compensation. Airlines cannot force you to accept vouchers, credit notes, or loyalty points instead. If an airline offers vouchers, you can decline and insist on a cash payment.

Can the airline refuse to pay because of a technical fault?

No. The UK Supreme Court ruled that technical faults are not extraordinary circumstances. Mechanical problems, IT failures, and other technical issues are within the airline's control, so they must pay compensation for delays caused by these issues.

Can I claim flight delay compensation for a child?

Yes. Every passenger is entitled to compensation, including children and infants who had their own seat. A family of four on a delayed long-haul flight could claim £2,080 in total (£520 per person). Use Paybacker to generate claim letters for every member of your family in seconds.
