Northern, I guess don't really know for sure. When you had your locks cut off, did anyone leave a note for you?
All I do know for sure, is that I keep my real valuables in my carryon, and lock up my suitcases. Those new suitcases with the built in locks, can't be cut off, they are part of the bag and zipper system.
Also like a suitcase belt with the TSA lock included in the buckle.
