This is pretty cool if it really is TSA approved. I know that in the past decade people have really moved away from locking their luggage because the TSA has requirements about accessibility and things like that. I would be interested in seeing a official document from the TSA saying this is approved. Also it would be cool to know how durable that cable is. Can it easily be cut with some side cutters or linesmen pliers? I think this is a really awesome design. Thanks for sharing. Nice hunt!
