Were You Owed Flight Compensation?

Delays over 3 hours, cancellations and denied boarding can entitle you to fixed cash compensation under UK and EU rules. Prooof works out exactly what you're owed.

What is UK261 / EU261?

UK261 (and its EU261 equivalent) is the regulation that sets fixed compensation rates when airlines disrupt your journey. It applies to flights departing the UK or EU, and to flights into the UK or EU on UK/EU carriers - regardless of ticket price or airline goodwill policies.

When you can claim

  • Arrival delays of 3 hours or more
  • Cancellations with less than 14 days notice
  • Denied boarding due to overbooking
  • Missed connections caused by an earlier delay
  • Disruptions on UK/EU airlines flying into the UK/EU
  • Up to 6 years after the affected flight

Frequently asked questions

How much flight compensation can I claim?▾

Under UK261/EU261, compensation ranges from £220 for short-haul flights to £520 for long-haul flights delayed by 3+ hours or cancelled less than 14 days before departure.

Which flights are covered?▾

Any flight departing from a UK or EU airport, plus flights into the UK or EU on a UK/EU airline. The route - not your nationality - determines eligibility.

What counts as a qualifying delay?▾

A delay of 3 hours or more on arrival, a cancellation with less than 14 days notice, or being denied boarding due to overbooking.

What if the airline blames bad weather?▾

'Extraordinary circumstances' (severe weather, air traffic strikes, security alerts) remove the airline's liability. Technical faults, crew shortages and most operational issues do not.

How far back can I claim?▾

You can claim for flights from the past 6 years in England, Wales and Northern Ireland, or 5 years in Scotland.
