For anybody considering spirit, here's how my first year went. I made $21,500 before tax and $25,500 with per diem. I usually drop around 2-3 days a month since it's not worth 38.50 to be on the road (hardly worth 72 either). I was on training pay for 75 days, 1750/month.
Also, maybe someone currently in training will chime in but I've heard the new hires there now have been left behind to fend for themselves in the hurricane. No positive space out and no one is able to get a hold of anyone for assistance. But hey, they really care for their employees.
