@ Vortac1. As someone in the lower 1/3 group I can say that PBS makes all the difference. For 3 months straight I got 90% of what I bid for and the rosters are awesome. BUT it all depends what you want out of PBS. You got to be smart too. No point bidding for Belgrade or the likes.
I'm averaging 15 ' days off' a month as a junior F/O...and 80 block hrs.
