I would not worry about it too much. I have flown with my ar and pistol and the max
amount of ammo in my wifes, daughters, and my check on bags and didn't get much
of a reaction from the people at the check in counter. The scary part came was
while we were at the gate waiting in Detroit. The airline counter called my name,
and when I went up, there was a guy and girl looking very concerned and
the guy asks me in a real low voice "Sir, where are your firearms?" I about shit.
I laughed at him and said "Well I would think you know that better than
I do seeing that it is required that I declare them at time of check in, and they are
obviously not in my possession right now!" Pretty fucking funny, and this is post
9/11. Needless to say that they ended up confirming the location of my guns, and
stopped looking at me like a terrorist. So hopefully you have no troubles or at least
a good laugh at other peoples ignorance. As long as you follow the rules you'll be
fine. Good luck!
