Denied boarding and overbooked flights: your rights

Updated 5 November 2026 · General information, not legal advice.

Quick answerIf an airline refuses to let you board against your will, for example because the flight is overbooked, you may be entitled to a refund or alternative flight, care while you wait, and compensation. Check the CAA's guidance for the amounts and how to claim.

What counts as denied boarding

Being refused boarding when you turned up on time with a valid ticket and documents, for example because the airline sold more seats than it had. It does not usually cover being refused because of your own documents or behaviour.

What to do

  1. Ask for the airline's offer in writing.
  2. Do not accept a voucher in place of your rights without understanding what you are giving up.
  3. Keep your boarding pass, booking confirmation and any written refusal.
  4. Then claim from the airline.
The rules and amounts for denied boarding are explained by the CAA. Check them for your case.

Frequently asked questions

Can I claim if I volunteered to give up my seat?

Volunteering usually changes what you are owed, so read what you agree to before you accept.
