It is. The flight I am looking at is a direct flight, but I've also had flights in the past that had me stopping in Chicago (for example) before for a quick layover... I suspect in a situation where I had a layover in a State that did not recognize my permit, even though I am not carrying in the state, that'd be bad? I try to avoid O'Hare nowadays if I can.
Since your firearm will be in a CHECKED bag, you are not carrying it, and it will be transferred to your next aircraft. If Chicago is your destination, that's a different matter.
Unload firearm and magazines. Place ammo back in factory carton. Lock BOTH in a hard side case. Place that case in your suitcase and lock it with a lock only you have the key to. NOT A TSA LOCK. Upon check-in, declare the firearm when you check your bag. They will have a little form for you to place inside the gun case. They will tell you to wait for 5-10 minutes while TSA/Baggage clears it and then tell you to proceed to the gate. On ocaission, TSA will come during that 5-10 minutes and ask you for the keys so they can inspect the firearm. This is done behind closed doors outside your presence. They will bring your keys back and off you go. So give yourself a little extra time in case they want to inspect it.
It's really a simple process.
