Dont see the problem, i'm damned junior in the right seat of the 400. Always get a trip line so long as i'm not silly and that gives me much more flexibility than my previous companies like it or lump it roster. At least i have some choice, even with a blind line theres a seed that gives you some chance of a day off (400 only). I realise in present circs it will be 15 yrs to command but i'm taking home more than previous co would pay a skipper. (i even get to sit in the left seat sometimes!). That said, if i was looking at a command on a big jet within a few years, or over say 35 I would think twice before jumping, but its really not that bad.
Any new aircraft in the next 5-10 years will of course shorten command time radically.
