With the new contract, you can bring in 90-100k in the first year if you hustle and live in a domicile.
Second year 100-120 maybe?
Again, this is all a function of how much you are willing to work. If you just fly your line, you will gross about 1200 multiplied by your TFP rate. It is pretty easy to work more at SWA if that's what you need to do.
First year guys can get second year rates for any flying they pick up out of open time. That's a useful tool that many use to cushion the blow.
I would say you will be matching your current take home around year 3 without working hard at all.
