Just read and follow the rules. It is surprisingly simple and easy. Have flown several times with both handguns and ammo and on over 50% of the times the check counter didn't even ask me to open the case. Only opened the suitcase to insert the disclosure card. PS No tsa locks on the gun case. Regs require that only you have the keys. I use tsa locks on the outer case just to keep it from popping open in handling. Have never, I repeat, never had a problem or issue. On one occasion flying out of Anchorage, my bag with the firearm case was sent over to a special TSA inspection room and I was ask to open the outer case but not the gun case. They found and confiscated a bic lighter but missed a spray can of [exposive] WD-40. Again the key to all of this is to understand the rules and follow them. A suggestion that I was given by friends is NOT to fly with a firearm that I am really attached to. That heirloom or expensive item might be more of a target for thieves but more importantly you would feel really bad if it was lost.
