A delayed flight is bad enough; not knowing what you're owed makes it worse. Under UK261 — the UK's version of the EU passenger rights regulation — travellers have clear entitlements when flights go wrong, and they're more generous than most people realise.

The headline figure: if your flight arrives more than three hours late and the airline is at fault, you could claim £220 to £520 per person. It's arrival time at your final destination that counts, not take-off time, and the amount is fixed regardless of what you paid for your ticket — a cheap fare doesn't shrink your payout. Flights under 1,500km earn £220; 1,500–3,500km gets £350; longer hauls earn £260 if you're three to four hours late, jumping to £520 beyond four hours.

You don't need to wait three hours for help, either. Depending on flight distance, the airline's duty of care kicks in after two, three or four hours, covering food, drink, communication and, for overnight delays, a hotel plus transport to it. If the airline won't sort these out, book them yourself and claim reasonable costs back — keep itemised receipts and skip the five-star suite, because the Civil Aviation Authority (CAA) says carriers are unlikely to refund luxury hotels, meals or alcohol.

If the delay hits five hours and you'd rather scrap the trip, you can walk away with a full refund for the unused legs of your booking, and on connecting journeys potentially a flight back to where you started. Just don't take the refund if you still intend to fly — you can't have both.

There are limits. 'Extraordinary circumstances' such as severe weather, air traffic control decisions, security risks, strikes by third parties and bird strikes release airlines from paying compensation — though ordinary technical faults generally don't count as extraordinary, a point the CAA is firm on. Even then, the duty of care still applies.

Connecting flights are another wrinkle. Book both legs in one reservation and your delay is measured against your final arrival time, so a missed connection that lands you three-plus hours late can still trigger compensation. With a self-transfer — separate bookings — those statutory rights don't bridge the gap between the two flights, although each individual flight is still covered.

Claims rarely happen automatically. Contact the airline, usually via an online form, and hold on to your booking confirmation, boarding passes and any correspondence explaining the delay. If your claim is refused, ask why; you can escalate to an Alternative Dispute Resolution provider, the CAA's Passenger Advice and Complaints Team, or simply push back if the airline has gone quiet for eight weeks.

This applies to any flight departing a UK airport (regardless of airline), arrivals into the UK on UK or EU carriers, and UK airline flights arriving in the EU. It's admin nobody wants after a long travel day, but with up to £520 per passenger at stake, five minutes of paperwork can turn a miserable delay into a modest windfall.
