And OP, I hope you reached your destination and your luggage followed you.

My sister was separated from hers for 10 days and by magical luck it was HER who found her luggage at CDG upon her return tp fly back to Boston. No she didn't fly BA, she flew LH from CDG. They claim that the tag had fallen and didn't know who it belonged to. If this is why , then what are those small stickers that they put around the luggage with a code, for?
