Mostly senior F/O's leaving and a captain every 5 or 6 months or so. Good training, great aircraft, crap sched on top of an all nights operation. So if you go,plan on it being a a short scheduled stop onwards to somewhere else. Back seat time is interesting,and a nice introduction to a large jet, expect to be there anywhere from 1-3 years.You just don't want to be in that seat when the music stops and the last '27 becomes beer cans.
