On a trip to Japan for a conference, my suitcase ended up in Bangkok. It was a non-stop flight from LA to Tokyo so I didn't bother with a carry-on. I did the conference and returned home without my suitcase, feeling a bit ripe. After I had been back two weeks my bag was finally returned secured with a nylon strap which had to be cut off. Everything was there just like I'd packed it before the trip.
