Monarch have told me that they are willing to pay compensation for a cancelled flight from 2008, but only if i can produce booking ref or boarding pass, which i don`t have. They tell me that their records do not go back that far (convenient), but that the flight was chartered by Thomas Cook. Thomas Cook told me, they cannot find any record of flight. I booked through Travelsupermarket.com, who tell me that they are just a portal, and do not have anything to do with bookings. I have looked into using the claims firms, but they require this elusive info also. Is there anyway through this brick wall?
