I'd say $45-50K for first year pay ($45/hour) after taxes. That's based on 1-2 months of Reserve.
I made $43K first year after taxes but about the first 6 months of that was on the old pay scale of $37/hour. I was on Reserve for 1.5 months. I don't fly excessively, and averaged probably about 85 credit per month (which is normal and what a typical Lineholder credit value is).
