I bring mine with me whenever I fly. Each airport and airline is different but a few things are consistent. First, the gun must be in a locked box, I use a small Pelican case just big enough for the weapon and 2 empty mags. The ammunition must be in a box "designed for that Ammunition". I use the box that the ammo came in. This must be in your suitcase, not in the locked box with the weapon. When you get to the ticket counter state "I need to declare a firearm". They will fill the firearms declaration tag out give it to you, now, depending on which airport, either a Port Authority Police or TSA will check that the weapon is empty, put the tag in the box with your gun and have you lock it and put the box in your suitcase. In one airport, they sent it straight to TSA and had me wait while TSA scanned my suitcase. In any case, this never took more than 10 minutes. In all cases at the other end my bag comes out on the carousel with everyone elses. Never had a problem and never has it taken more than a total of 10 or 15 minutes. One ticket agent wanted to put the firearms declaration tag on the outside of my bag, I politely asked her to ask the TSA and they told her to put it inside out of view. Don't be intimidated, it is quick and painless.
