So I'm going to be taking a trip from NC to AZ this spring, and I'm going to bring my carry gun with me. I've read TSA's rules, and the plethora of threads about how to do it, but I do want to ask two questions... 1, when do I declare that Box A has a firearm and meets TSA's guidelines, and Box B has ammunition, and also meets TSA's guidelines? I haven't flown since I was a kid, so I don't know how the process goes now. 2, what's been your experience? Good? Bad? A hassle? Thanks!
