Who can use this letter
- Your flight departed a UK airport, on any airline
- Your flight arrived in the UK on a UK or EU airline
- Your flight arrived in the EU on a UK airline
- Arrival delay was 3+ hours, or the flight was cancelled with under 14 days' notice
- The cause was within the airline's control (technical fault, crew shortage, overbooking) — not severe weather, ATC restrictions, or security threats
Before you send it
- Confirm your compensation tier: £220 (up to 1,500 km), £350 (1,500–3,500 km), £260 for 3–4 hour delays or £520 for 4+ hour delays (over 3,500 km).
- Gather your booking reference, flight number, date, and route — boarding passes help but are not required.
- Note the reason the airline gave for the delay, if any (check departure boards, airline app, or emails).
- Address the letter to the operating airline's customer relations or compensation team, not the travel agent or OTA you booked through.
- Keep a dated copy of what you send and how you sent it.
The template
Fill in every [BRACKETED] field with your own details before sending — do not send
this letter with placeholders still in it.
How to send it
- Prefer the airline's own online UK261/compensation claim form if one exists — it routes straight to the right team.
- If posting or emailing, address it to "Customer Relations" or "Compensation Claims", not general enquiries.
- Send by email or recorded post so you have a timestamp and delivery record.
- Keep a copy of everything you send, along with any reference number the airline issues.
If you don't get a response
Airlines typically respond within 4–12 weeks. If you hear nothing after eight weeks, or your claim is rejected and you disagree with the reason given, escalate using our CEDR / Aviation ADR escalation letter or complain to the Civil Aviation Authority.
