Protect Your Luggage

When waiting in line or sitting in the airport (or anywhere else, for that matter), always have the strap(s) to your carry-on luggage wrapped around an arm or a leg, then they won't disappear without your knowledge. I carry this suggestion to the extreme if I am in a questionable area. I have even straddled my large bags when I felt it necessary - or at least have them touching my leg so I'd know if they were moved.
