DW shows me these TSA approved locks for our flight checked luggage at the store last night. Seems reasonable that they have a master key that works all TSA approved locks, but I still scratch my head.
Anybody use these special new locks for their luggage? Does anyone have an alternate method for locking up checked luggage?
Sage wisdom, masterful counseling, and high value tidbits are appreciated.
