Flying down, handgun stowed and declared at Love Field checkin-counter with no incident. Very easy and professional. I was simply asked to "place card on top of the contents inside my suitcase".
Short stay in San Antonio and then...
Upon my turn at Southwestern's check-in counter, I again declared my firearm in my suitcase, stating it was "unloaded and locked in a handgun case". I had opened the suitcase while making the statement.
I was then handed and filled out the declaration card. 30 sec later, I then handed it back to the ticket agent and he then stated "ok, open the case and place it with the firearm".
I had only 1 suitcase...it was already open...the only other "case" to open was...my handgun case.
I replied "Excuse me?"
His face then went confused...and we both seemed to agree I needed to bring my luggage to luggage security, which at that time I was asked to place the card in my "suitcase".

Perhaps it was in-experience, confusion on semantics by me, him, or both of us. Maybe they should be the ones to place it in the "case".
Thoughts?
