The good thing about that is only once several years ago had I ever needed to use them to get somewhere. It was an experience I will not forget and reinforced my idea that I will NEVER pay to fly that airline and I will continue to avoid them to the max extent possible free.
There was a flight attendant carrying a sound making toy dinosaur who was continuously using it over the PA before we left. Then later in flight (night flight) came up in the row behind me (as I was sleeping) and made the noise RIGHT IN MY FREAKING EAR. Seriously, how inconsiderate can you be? Fornicate that airline.
The times I jumpseated on SWA, back in the day when I did jumpseating long ago, I do remember first trying to get on a UAL 727 flight, but ended up getting bumped by a higher priority, and even though there were many open seats in the back, the UAL pilot could only take as many jumpseaters, as there were jumpseats on the aircraft, per policy.
Wandered over to SWA and a 737-200, and same thing......told the jumpseat is already taken. As I thanked the gate agent for the info (all pre 9/11 travel, mind you) and began to wander away to find another possible JS opportunity in my little JS book we were given back then, the gate agent told me to talk to the Capt anyway when he shows up. I wait, the crew shows up, I talk to the Capt and make the standard greeting and ask about the jumpseat, and he says they've got about 25 or so open seats in the back, and feel free to grab one. Once onboard, there were about 12 other jumpseaters going to work or going home, also sitting in the open seats in the back.
So, that was my experience. Positive. I understand the UAL Capt had policy to follow and couldn't deviate from that, certainly nothing held against him for that, although the policy seemed a bit dumb. But SWA was more than accommodating, whether it was policy to be so, or whether the Capt used his own discretion. I never knew which one it was.
