since we can no longer lock the samsonites, we use duct tape, with the combination printed on the tape, just below the old combination lock on the hard samsonites. this prevents the bags from getting locked inadvertently. Yes, when the bags are opened, a printed tsa notice appears inside the bag. We put an exterior strap around the case. lthese have been coming thru okay. but, rule remains, put nothing of value in the checked luggage only in the carry-on or in your briefcase....it also helps to travel with cheesy mass market luggage with lots of scuffs and scrapes--no one wants to take that stuff!...... we finally bought big softsides just so we could lock some of our better stuff, but if thieves really want your stuff, they will take it!l it sure isn't like the old days!!
