Thank you all for your responses. Here's an estimate of how much you should expect to make for anyone that is in a similar situation. This is considering that: Atlas will get a CBA on 2021 (similar to ATI pay scales), and PSA flow to AA in 7 years. Both include hourly pay rates, per diem, no open time or any other soft pay.

2025: $187000
2026: $192000
2027: $198000
