Just came off a flight last night at DXB. On boarding, the purser took my jacket but never handed back to me on landing and I forgot to ask. Only realised when I was in the Chauffeur car heading home.
Called the Lost & Found office at the airport, they said nothing has been handed over until now (more than 24 hours).
Expect the purser to have handed it to them or the airline should have tried to get in touch. I mean they can trace my details from the seat number and there were only three of us in the F cabin, surely they should've put in a little effort.
So far it looks like there is no hope.
