According to the "Minimum Raise Trip Rate" table, the raise starts on 9/02, and year 1 is 35.40. Year 2, on 9/03, is 62.12.
78.58 for a 3 year FO on 9/04, then 90.64 and 104.25.
They say to figure 500-600 bucks for per diem for lineholders, and I've heard lines average 92-95 TFP's (Trips for Pay) a month, though you may be able to pick up more if you look hard enough.
My buddy in MDW got hired last October, commutes, says he has been averaging at least 105 TFP's a month by picking stuff up. You can pick stuff up from individuals for straight pay, or if you get it from open time (if there is any) I think they pay second year rates for first year FO's.
On the down side, I hear there's even a few Captains out there who are still trying to pay off that expensive leather through payroll deduction.
As for the other question, I have absolutely no idea what the technical minimum gurantee is, or how many TFP's we get during training.
