- Aeromexico: Covered only if a UK or EU airline operated the flight
- British Airways: UK261 – UK or EU airline flying into the UK
Compensation is fixed by distance, not by the ticket price, and is paid per passenger, children included. It is not due if the airline proves extraordinary circumstances.
