Flying with guns ain't hard. Every airline is a little different, but the gist of it goes like this:
The first thing to do is tell the check in person you'd "Like to declare an unloaded firearm." They say, "OK."
Next, they'll grab an orange card and write the flight info on it. They'll hand it to you to sign and insert it into your locked case. When done signing the card, ask if they'd like you to open the case. They will say, "Yes."
A pistol only needs to be in a tiny, lockable case. This can then be inserted into a traditional checked bag. Long guns need to have two locks, but I don't think you need that for pistols.
Once you drop the card in the case and lock it up, seal up the luggage and hand it over. At this point you're likely done—unless security wants to get into your case, which they sometimes do.
The best bet is to tell the check-in person that you'll hang around until the bag clears security. In 5 to 10 minutes, you need to pester them again and ask if you're good to go through security checkpoint. They'll quickly check and say, "Yep, all good. Thank you."
I use the below SnapSafe case for pistol travel. Good luck and enjoy your trip!
