Claiming compensation for a delayed flight in the UK is one of those jobs everyone puts off — and airlines quietly rely on that. The money is real, though: up to £520 per passenger, set by law, and you can claim for flights going back up to six years. If you’ve ever sat on a plane at the gate for four hours wondering whether it was worth complaining about, this guide is for you.

I’ll be honest: the process isn’t complicated, but it is fiddly, and airlines will try the standard rejection lines first (“extraordinary circumstances”, “air traffic control”, “weather”). Most of those rejections don’t survive a proper challenge. Here’s how the system actually works.

Delayed flight compensation UK: the amounts

Under UK261, the compensation is fixed by flight distance, not by ticket price — so a £40 Ryanair fare can still yield £220. The bands are:

  • £220 — flights of 1,500km or less (e.g. London to Paris, Manchester to Dublin).
  • £350 — flights between 1,500km and 3,500km (e.g. London to Athens, Edinburgh to Tenerife).
  • £520 — flights over 3,500km (e.g. London to New York, Manchester to Dubai).

These apply per passenger, including children — a family of four on a delayed long-haul flight could be owed over £2,000. That’s worth an hour of paperwork.

Are you actually eligible?

Three conditions need to line up. First, the delay must be three hours or more, measured at arrival — when the aircraft doors open at your destination, not when it takes off. Second, the flight must be covered: departing from a UK airport on any airline, or arriving in the UK on a UK or EU carrier. Third, the airline must have been responsible. Technical problems, crew issues and late inbound aircraft all count against the airline. Genuine extraordinary circumstances — volcanic eruptions, security threats, extreme weather, air traffic control strikes — let them off.

The grey area is where most claims are won or lost. Airlines love blaming “weather” for what was actually a crewing problem. If you suspect this, ask the airline for the specific reason in writing, and check flight-tracking data for that day. Other aircraft taking off normally in the same “weather” is powerful evidence.

How to claim, step by step

Start directly with the airline — use their online complaint or claims form, and include your booking reference, flight number, date, and the length of the delay. Be polite but specific: state that you’re claiming under UK261 and name the amount. Keep a copy of everything you send.

If the airline rejects your claim or goes quiet for eight weeks, don’t give up — escalate. You can use an approved Alternative Dispute Resolution provider (the airline’s website must name theirs) or take the claim to the small claims court via Money Claims Online. The court fee for a £220 claim is £35, and airlines very often settle once court papers land. The official government guidance on flight delay compensation explains your escalation options.

A word on claims companies: they’ll take 25-35% of your payout for doing what I’ve just described. For a straightforward claim, do it yourself. Only consider them if the airline has dug in and you can’t face court — and check their fee cap first.

Common mistakes that kill claims

  • Accepting vouchers instead of cash. Airlines may offer £300 in vouchers “as a gesture” — you’re entitled to cash, and vouchers usually expire.
  • Missing the six-year deadline. In England and Wales you have six years from the flight date (five in Scotland). Old delays still count.
  • Claiming against the wrong party. If you booked a package holiday, the airline still owes the compensation — but your tour operator may also owe you under package travel rules.

If your delay turned into a full cancellation, the rules shift slightly — see your rights when a UK flight is cancelled for the cancellation-specific protections. And if you’re wondering how early to turn up so a delay doesn’t become a missed flight, our advice on how early to arrive at the airport for European flights will help.

“Extraordinary circumstances”: what it really means

This phrase is where airlines hide. Genuinely extraordinary circumstances — things no reasonable airline could avoid — include volcanic ash clouds, drone sightings closing an airport, security threats, extreme weather, and air traffic control strikes. What doesn’t count, despite what rejection letters claim: most technical faults (the European courts have been clear that technical problems are part of running an airline), crew shortages, late inbound aircraft, and routine operational decisions.

Strikes are the tricky middle ground. Airline staff strikes (their own pilots or cabin crew) generally don’t count as extraordinary — it’s their workforce. Air traffic control strikes do. If an airline cites a strike, check whose staff were striking before accepting the rejection.

Escalation: ADR, the CAA and court

If the airline says no and you disagree, you have three escalation routes. First, an approved Alternative Dispute Resolution (ADR) scheme — free for you, binding on the airline, and decided by an independent adjudicator. Every UK airline must belong to one or accept the CAA’s complaints process; their website must tell you which. Second, the CAA’s own passenger complaint service for airlines without ADR. Third, the small claims court — Money Claims Online, £35 fee for claims under £300, and airlines settle the overwhelming majority once proceedings start because sending a solicitor costs more than paying you.

Whichever route you take, organisation wins: a single document with your booking reference, flight details, the delay length, the airline’s responses and your receipts. Adjudicators and judges love a clear paper trail — and so, incidentally, do the claims companies who’d charge you 30% for assembling it.

How long does a claim take?

Set expectations: a straightforward claim paid without argument takes 2-6 weeks from first contact. A rejected-then-escalated claim takes 2-4 months through ADR. A court claim takes 3-6 months but has the highest success rate for disputed cases. None of this is quick, which is exactly why most people give up — and exactly why you shouldn’t. Put the claim in, diary a follow-up, and let the process work. The six-year deadline means there’s no rush to start, but there’s also no reason to wait: evidence is freshest now, and the money earns nothing sitting with the airline.

One more thing worth knowing: compensation is per passenger, per flight, and it’s separate from any refund or re-routing you’re also owed. A cancelled-then-delayed rebooking can generate multiple entitlements on one trip. Check every disrupted flight you’ve taken in the last six years — most frequent flyers are sitting on at least one valid claim they’ve never made.

Don’t leave the money on the table

Delayed flight compensation in the UK is a genuine legal right, not a favour, and the six-year window means most of us have at least one claimable flight in our past. Check your old bookings, gather your evidence, and put the claim in. The worst outcome is a polite no — the best is £520 landing in your account for a delay you’d almost forgotten about.
