^ Echo everyone above

As soon as I lay my hands on my checked luggage, I know I'm going through TSA security.

The premise is, since I have access to my checked luggage, I could remove something that wouldn't be allowed through a checkpoint...like a knife...

On the other hand, it's a great way to stash the duty-free booze into your checked bags, so it's not in your cabin carry on, then to be gleefully confiscated by the TSA as excess liquids

All the best, James
