6 FIELDSIt depends
It depends — you may be owed ~£350 if it was the airline’s fault
- Your flight is covered by UK261 and the delay is long enough to qualify — but whether you’re actually owed money depends on the cause.
- If the delay was the airline’s fault (for example a technical or crew problem), you could be owed around £350. If it was caused by extraordinary circumstances like extreme weather or an air-traffic-control strike, no compensation would be due.
- Ask the airline for the specific reason in writing, then check your claim.
You usually have up to 6 years to claim in England, Wales & Northern Ireland (5 years in Scotland). This is for information — it does not affect the estimate above.
