That's separate from the issue Chasen is talking about--that specifically relates to flight attendants and the cabin jumpseat. I don't know what's going on with that.
The form you guys got is the UAX jumpseat priority form. It came about because UAL's software *always* prioritizes UAL pilots ahead of UAX, no matter what airline it is. This meant that even though, say, a RAH pilot has priority on RAH over mainline, the gate agents were saying the mainline guy had priority. This was really pissing UAX commuters off, so the form became the official UAX jumpseat priority method.
There were several changes in the form you guys probably got: first, you and ASA were on there, and I think both of you prioritize your own pilots first on UAX flights followed by UAL/UAX on time of check-in only. Mesa does this as well. ASA and Skywest put each other ahead of everyone off-line followed by UAL/UAX time of check-in. TSA and Gojet put UAL ahead of off-line UAX, which they did because they got UAL to prioritize them ahead of other UAX folks...which caused ASA to put TSA/Gojet behind other UAX (good for them). It's all extremely 4th grade schoolyard.
The best is RAH, though--they (obviously) put Frontier first, but then they now have UAX *ahead* of UAL, regardless of time of checkin. I guess UAL was trying to put them behind the rest of the UAX carriers and it backfired on them. It works for me because 90% of my commutes are on RAH and the majority of the commuters on this route are UAL guys.
