Thankyou Mikke for your informative post.
My bag did not arrive with me in DXB and it was sent on the next flight from AMS 24 hours later.
I bought shorts, T-shirt, etc to last until my bag arrived and I'm going to claim for these. KL has given me a €25 voucher to redeem against another flight to say sorry but it is unlikely I will use it. What are the chances of me getting some free miles? If I get them, how many am I likely to receive?
