All I had on my luggage tag was my airline FF traveler numbers. I know that freaks people out, but I did not have my name, number, address, or any other personal information whatsoever on the bag, nor on anything within the bag.

They way I figgured it, the ones who would most want that info were the airlines with a mishandled bag. Or, it was likely to e found somewhere in an airport. Places where they can bring it up to an airline counter and say they found this. The airlines would probably be wise enough to recognize an FF number, and if they were legit they could then look up the contact info.
