In the case of the "jerk", I met him at the gate as he was walking down, and let him know I'd be requesting a jump. He was curt and sort of looked me over like I was some pest. I waited 45 minutes to walk down and show him my ID's, and at that point he declined to give me the jumpseat or a reason. It was only a short flight from SAT to Love Field. I can't remember for sure, but I don't think that it was a full flight. Anyways, I could tell the gate agents really didn't like this Captain, and they stated this was pretty much par for the course with him.
The 2d time, I was in ABQ. Again, I've sort of forgotten the details, but I recall that there was an FAA guy in the 1st jumpseat. I'm guessing he was acting in some official capacity. The jet had two jumpseats. When the Capt cleared me to take a seat in the cabin, I told him there weren't any and the 2d jumpseat was the last seat on board. At that point, he said that wouldn't work, but that there was another plane in about an hour, so I shouldn't have a problem getting out of ABQ. If he was getting a line check or whatever, I certainly don't fault him for denying me the seat. He's got to look out for his and SWA's best interest, and if that means denying me the seat, then so be it. And I was able to get out of ABQ on the next flight about 2 hours later. No big deal.
