Welcome, Sgt. Kabukiman! I cannot answer your question, but I want to thank you for thinking we can be a resource on gun law. You came to the right place. I am sure someone here will be able to help you.
Now, if you are ever curious about Alabama gun law...
Anyway, I am anxious to hear the answer to your question. I wondered about how transporting a gun on an airplane works when one of the terminals is in an extremely gun-unfriendly State. If both endpoints are gun-friendly, its easy, just follow the federal rules. When a State like NY gets involved...uh oh.
We have had discussions regarding transport of guns on airplanes before, so I am sure we have someone here who can help you. Again, welcome.
