I think I already know the answer to this. Lately I have been traveling a lot and have taken my firearm wherever there had been state reciprocity for conceal carry. So far, I've had no problem when declaring my firearm with the agent. A few agents had seemed perplexed at first. However, flying home last night I thought, "Can an airline refuse to ship my firearm?" I would be in deep kimshi on some occasions if I had to either take the firearm back home or have an FFL ship it back.
