Your flight is delayed by four hours. You’re sitting in the terminal, eating a £9 sandwich, watching the departure board lie to you. What most UK passengers don’t realise is that this miserable situation comes with money attached — potentially £520 in your pocket, by law. If you’re asking how to claim compensation for a delayed flight in the UK, here’s the complete guide: what you’re owed, when the airline must pay, the exact process, and the tricks airlines use to avoid paying (and how to beat them).
The legal framework: UK261 — the UK’s retained version of EU Regulation 261/2004, which still applies to flights departing the UK (and EU airlines’ flights to the UK). It’s one of the strongest passenger-protection regimes in the world. Know it, use it.
What You’re Entitled To (The Numbers)
For delays of 3+ hours on arrival (note: arrival time, not departure — it’s when the doors open at the destination):
- Short-haul (≤1,500km): £220
- Medium-haul (1,500–3,500km): £350
- Long-haul (>3,500km): £520
For cancellations: same compensation plus the choice of rerouting or refund. For denied boarding (overbooking): same compensation.
Separate from compensation, the airline must provide care and assistance during the delay (which is separate from the travel insurance you should also hold): meals and refreshments (vouchers — ask if not offered), hotel accommodation for overnight delays, transport to/from the hotel, and two phone calls/emails. This duty applies regardless of the delay’s cause — even for “extraordinary circumstances.” Keep receipts for anything you buy yourself; the airline must reimburse reasonable costs.
When They Must Pay vs When They Don’t
They must pay: technical faults, crew shortages, crew going over hours, operational decisions, late inbound aircraft (knock-on delays). The key legal test: was it within the airline’s control? Most delays are.
They don’t have to pay (“extraordinary circumstances”): severe weather, air traffic control strikes, security threats, volcanic ash, medical emergencies. Note what does not count: ordinary bad weather at the destination (unless it closed the airport), most strikes by the airline’s own staff (court rulings have repeatedly held these are within the airline’s control), and technical problems (the most common excuse — and legally invalid in most cases).
The airline excuse playbook: expect “extraordinary circumstances,” “weather,” or “air traffic control” as blanket refusals. These are often wrong. Challenge them: ask for the specific reason in writing. Check whether other airlines were flying normally at the time (if they were, it wasn’t the weather). The UK Civil Aviation Authority website has guidance on what counts — and a complaint process if the airline stonewalls.
The Claim Process: Step by Step
- At the airport: document everything. Screenshot the departure board showing the delay, keep your boarding pass, note the actual arrival time (doors open, not touchdown), keep receipts for food/hotels, and get the airline’s stated reason for the delay in writing (ask staff or check the airline’s app/notifications).
- Claim directly with the airline first. Every major airline has an online compensation claim form. State: flight number, date, booking reference, the delay length (arrival), and the compensation amount claimed under UK261. Be polite, factual, and specific. Keep copies of everything.
- Give them 6–8 weeks. If no response or a refusal you disagree with, escalate.
- Escalate to ADR or the CAA. Airlines must belong to an Alternative Dispute Resolution scheme (check which one — it’s on the airline’s website) or you can complain to the CAA. ADR decisions are binding on the airline. This step resolves most wrongly-refused claims.
- Last resort: Money Claims Online. The small claims court — £35 fee, usually done on paper, airlines often settle when they see the court papers. Passengers win the overwhelming majority of valid UK261 court claims.
Don’t use claims companies unless you must — they take 25–35% of your compensation for filling in a form you can fill in yourself. The process above is free and straightforward. (If the claim is complex or very old, their cut might be worth it — but try direct first.)
Time Limits and Gotchas
- You have 6 years to claim (5 in Scotland). That delay from 2022? Still claimable. Dig out old bookings — many people are sitting on unclaimed compensation.
- Connecting flights: if booked as one ticket, the delay is measured at the final destination — a 1-hour delay on leg one that causes a missed connection and 4-hour late arrival = full compensation.
- Who claims: each passenger claims individually — including children (full amount each). A family of four on a delayed long-haul flight = £2,080. Worth the form-filling.
- Airline must reroute at the earliest opportunity for cancellations — if they offer a flight tomorrow but another airline flies today, you can book it and claim the cost back (keep it reasonable).
- Brexit didn’t remove your rights: UK261 mirrors EU261. Flights from the UK on any airline, and flights to the UK on UK/EU airlines, are covered.
For the broader picture of your travel rights, the CAA’s delays and cancellations page is the authoritative source, and our layover comfort guide helps with the waiting itself.
Codeshares and Non-UK Airlines (Know Your Coverage)
UK261 covers flights departing the UK on any airline, plus flights arriving in the UK on UK or EU airlines. That leaves a gap: flying to the UK on a non-UK/non-EU airline (say, New York to London on a US carrier) is not covered by UK261 — though US Department of Transportation rules give you different (weaker) rights. For codeshares, the operating carrier’s nationality usually determines coverage, not the airline you booked with. When booking long-haul returns, this is worth knowing: the outbound (UK departure) is always covered; the inbound depends on who’s actually flying the plane. If in doubt, the CAA’s guidance has a coverage checker.
The takeaway: UK flight delay compensation (£220/£350/£520 for 3+ hour arrival delays) is a legal right, not a favour — document everything at the airport, claim direct with the airline, challenge bogus “extraordinary circumstances” refusals, escalate to ADR/CAA if needed, and never pay a claims company 30% for a form you can fill in yourself. Check your old flights too — six years of delays might be sitting there unclaimed.
