i use a jb rugged case which i put in a duffle bag
i lock it with tsa approved locks thru the opening in the grips on the zippers
the duffle bag is locked the same way
i have traveled several times this way with no problem
once the there was tape i forget on the duffle bag or the case that indicated the locks were opened and my bag was searched
the cues were intact
So, the TSA locks mean exactly what? That the TSA folks cxan unlock and inspect but the baggage handlers can't? Is your stuff safer from being stolen this way?
