I've CC'd in the baggage claim area in the past, but now I prefer not to. For one, I can't imagine NEEDING a pistol there, and two - I damn sure don't want to be a MWAG when the Cavalry start arriving from every direction.
I've also heard that the place is considered private property, or city property, and even though CCW may be "legal" there, it's certainly frowned upon. I'm all about rights, but I'm also all about avoiding unpleasant situations whenever possible.
Once in a blue moon I may have to go out there as a non-traveler, but considering how rarely that happens I'll just take my chances that nobody's going to go on a shooting rampage. If someone does, I'll just find cover. I don't want to have a gun in MY hand when the return fire starts.
