What Air France or any other foreign carrier does with it's jumpseats doesn't apply in this case.
In the JetBlue case, I've heard they must have a seat open in back (FA JS?).
Another poster mentioned FAR's as if they are written in stone. That is a pretty good description. Nothing APA or AA does is going to change that. Best thing to hope for would be a familiarization program for FA's to ride up front. In the end a seat still has to be available in back so it's a moot point.
I would support letting FA's ride in an open CP Jumpseat strictly on Captains permission.
I do find the tone of many posters here somewhat amusing. "All for One, One for All", or nobody is superior or more special than others sounds great but lacking in practice. I don't seem to recall much indignation or sorrow here when the pilots took as much as a 50% paycut post 9/11, and still lag the industry leaders. <_<
Since I took a 100% pay cut I can assure you that am just as outraged over pilot pay cuts, (ramp, mechanics, lower management, et al). Especially given the bonus payments that "some" enjoyed. Reality dictates that just because you're driving the bus, you may be the team leader of that particular flight BUT you are not superior to any other front line employee just because you wear pilot's wings. I think that is a difficult concept for many pilots.
