Raptor, I just flew american airlines across country with my firearms and they require them to be in a locked rifle case but they will examine them upon cheque in so you will need to have the key on yourself. I have two of those walmart cases thats made out of some kind of durable plastic that cost around $20.00. Ammo cannot be stored with your rifle either. Allow yourself at least 2 hours for cheque in also . Each airline may have different regulations in the transporting of firearms so maybe cheque with your airlines to see if there is any diff. Bobby
