Departed DFW yesterday with the EDC and ammo packed in two separate hard-sided locked pistol cases inside a checked bag as per TSA and AA rules. The cases were not "TSA Locks". The luggage was also locked with TSA locks. Declared it, signed the statement which went into the bag. Uneventful and easy.
Proceeded to the gate. While I was chatting to the Gate Agent 30 minutes later, a TSA fella shows up, and asks the Gate Agent to page me. I introduce myself. TSA needs the key to the pistol cases. He was very polite and very professional. I gave him the key and obtained assurance he would return it and re-lock everything. He concurred, and confirmed the gun was not loaded and the ammo was also locked up.
Twenty minutes later he returned the key, confirmed everything was all re-locked, and told us to have a great trip.
Arrive in the City of Brotherly Love, reclaim bags, check locks and that the pistol cases are present and weigh the "correct" amount.
Arrive at hotel, check in, go to room, "load and arm up".......Happy happy happy! Re-read PA CHL, all well!
I sure like reciprocity!
