Maybe it's just a coincidence or plain bad luck, but on the last three flights taken (all UA), my checked bags have emerged with my FT Bag Tags missing. Since they have the plastic strap, it's impossible to tell if they've been cut off or just yanked off. My other ID tags always came out unscathed, although they're attached with the same type of plastic strap.

Just weird, bad karma, or maybe the FT tags are considered "collectibles"? I'll have to check ebay.
