i would be prepared for questions from the tsa as you do realize that their primary focus is to catch illegal aliens, folks with bogus i/d's and druggies, right?
but seriously, if they see it (n.b. if), i would expect questions and allow for extra time if they get "uppity, pull out your "it is only used for tobacco and if you don't believe me, please (n.b. please) bring over any leo you would like along with a drug sniffing dog" speech and let it play out as you have nothing to hide.
now with all of that, make sure you have a
tsa complaint form handy (thanks to
ND SOL) and be prepared to take names and badge numbers "just in case" as my gut is telling me you're gonna get haSSSSled
