I recently flew Southwest out of PDX to Spokane GEG. I decided to take my carry gun with me since my OR-CHL is good in Idaho, where we were headed. I packed my gun, unloaded and action open, in a locked metal case that I usually use as my car safe. I stored 3 empty magazines and a full box of 50 JHP rounds in a separate locked metal case. I put them in my checked luggage along with my holster and such. When I went to the Southwest counter I said, "I have an unloaded gun to declare." Her eyes lit up, as I had read they might, since this is presumably the most interesting type of event during a shift. She didn't even have me open the cases. I took the bag over to a special TSA desk at PDX. This woman swabbed my bag for explosives, but never even opened the cases. When she asked about the ammo, I just said, "It is properly stored in the locked case." She was fine with that. When I arrived at GEG, the bag just came out on the normal belt. It did have a notice inside that the TSA had searched the bag again. At Spokane when I returned, the process was almost exactly the same. AT GEG, the TSA agent did ask for me to open the locked case with the gun, but other than that, the experience was the same. In Portland, my bag also had a notice that they had searched it. I was quite pleased with how easy the process was!! On your next trip, consider taking your gun.
