I know. This happened in the US, should have mentioned that. My point was making sure you had a copy of the regs with you. For example I had a gate agent try to convince me that my ammo had to be in my gun case on a trip to RSA a few years ago. She did not know the differences between US and International policies. Or just this year a gate agent tried to tell me that I couldn't bring my rifle to Argentina, even though I had a permit. Once again I was saved by having copies of the regs.For international flights it must be separate from your gun case. You can do it inside the US though if airline has no policy against it.
