British Airways delayed luggage - compensation?

*Kat*

I travelled to Berlin for 5 days in December, my luggage was delayed and not delivered to me until my last day in Berlin. 

What are the rules around compensation for this? I paid £75 at the airport to put my bag in the hold so I'd like that back considering I had to wait 4 days to get it!

You have 21 days to make the claim so make sure you dont leave it too late.  In principle you are entitled to claim the things you had to pay for as a consequence of the delay (eg toileties, underwear, extra laundry etc)

Presumably this wasnt a cabin size bag hence you had no choice but to check it in?
