a couple comments...
Secondly, the one and only time I jumpseated on JetBlue, I had an experience similar to Jim's. I was jumpseating from BOS-DEN, and I was told by no less than 4 different people that I would have to help clean the cabin when we got to DEN. I was told by the ticket counter agent outside of security, the gate agent, the captain, and the lead FA. I have always helped out on my own cleaning up my area, and I didn't have a problem helping.....I just had a problem with everybody telling me I had to. Aside from that, everybody was very gracious and courteous. It was a little weird though. When we got to DEN, I started cleaning up, and waited until everybody was off the plane to get off. I went up to the blue-glove-wearing captain to thank him for the ride. he was still cleaning, and I think I pissed him off that I wanted to leave before the ENTIRE plane was cleaned. he said something like, 'well, I guess you're excused now.'
The whole experience was so cult-like, that I have since stopped updating my resume with them. I'm grateful for the ride, and it wasn't an unpleasant experience as much as it was a bizzare one.
