The TSA was cooperative, and I had no issues. On the flight to Colorado, I had no issues with the airline personnel, either. On the return flight, however, a Delta baggage handler lady, whose job it was to bring my luggage containing the firearm to the TSA (so they can say, "Yep, there's a gun in there alright"), insisted on bringing it behind closed doors to the TSA officials, and she requested my keys. I politely declined, and I explained the appropriate procedure to her, as gathered from the TSA's web site. She insisted, however, and I firmly refused at that point. She went in to speak to the TSA agent, and, although I could not hear her, I could see from her demeanor that she was "tattling" on me. No problem, though, I heard the TSA agent loudly proclaim (obviously so I could hear him) that he would leave the doors open so I could see the search and the gun case and luggage being locked back before returning the key to me. I then turned over the key to him, and he did exactly as promised. When he handed the key back, I told him I was sorry for being a pain, but I wanted it done correctly. He smiled, and said, "Please don't apologize. We are here to serve you, and you should make sure it is done correctly." I was, frankly, flabbergasted. I am so used to dealing with local Georgia potentates and their disregard for the rule of law, that the TSA man's pleasant and compliant attitude surprised me. I still don't like having to check it in at all, but it is good that they follow their own procedures and are pleasant to deal with. The Delta lady stompled away all huffy, probably wondering if she would get a tip!
