Hello all, I would need the help of someone working for the airline who has been in this kind of situation.

I have just landed in BUD travelling on staff travel standby ticket, but my luggage including all my clothes and Christmas gifts have not.

Can I claim from BA?
Or can I claim from AMEX Platinum?
What are the limitations?

I need to buy a few things like tshirt jumper and a pair of jeans and pants, toothbrush etc.
