Two things I tried:

1) I wore my old Style Amerikilt with the Cotton Sporran because I feared my regular one would be confiscated by overzealous employees. However, I forgot all the medal buttons and got a private search.

2) At the airport, I gave my wife, my ID and put my sporran in the suitcase. When I got back to Boise, I put the sporran back on at the baggage claim.

I prefer #2 much more.
