Fatbus,
I think you're right about people leaving but I think what is swinging decisions is actually the numbers joining...considering one of their grand plans was to recruit heavily onto the 330 this year in order to send us night-turn experts onto the 380, there seems to be a distinct lack of 330 courses on the list.
As long as they only want 'bus and Boeing guys, then I think they're getting stretched. Don't see them being at breaking point yet though, there seem to be plenty of guys filling 380/777 courses at the moment.
