Yes on the above. Look up on the airlines website under security/firearms and it will outline what needs to be done.
I locked my unloaded firearm in the case it came with and had it inside my luggage bag. Do not lock your luggage bag! Mag's (empty) and ammo locked in another case and stored in my other luggage bag. At ticket counter, tell them you a declaring a firearm. An agent will then ask you, "where is the firearm" followed with, open the bag and then case (pretty much follow their instructions). A tag is written up and They place it on the weapon. Lock the case and close your luggage bag. You will be escorted to xray machine where your luggage will be placed on conveyer and gone through security. It will now go with everyone elses baggage. When you pick up luggage at destination, you should be all set. It's only when your checking in luggage. I could get more in depth but YOU need to follow up on your own for this information. The above mentioned is from my scenario when I flew out of Boston, MA. to FL.
Like mentioned eariler, go to airline website and look under security/firearms and it will guide you through. When you think about it, alot of folks who hunt need to travel by airlines and you really don't hear any news about firearms at airports etc. That's because everything is proper when they check in. The only thing you hear is when someone is caught with a firearm in their pocket or something like that. Then they say, "oh, I forgot it was in there"! It's a very simple procedure. Just go by the guide lines and you should be golden. If you do a search on here, you will find more info on this question. Good luck!
