Thanks for the info everyone. I'm not Jetblue, I am Spirit, but I do agree that Jetblue is always a huge help and very pleasant and welcoming.
Donotreset, I am not trying to ride in the physical jumpseat on AA, just a seat in the back. Oddly, our pilot js agreement with AA is domestic only for us ont heir aircraft, but is wide open for them on ours. I know of a few other carriers that have the same unfair agreement with AA and its puzzling.
Thanks for all the info guys! Please keep it coming. Trying to get out early tomorrow without having to beg an AMR buddy for a D3 pass.
