Why do you want to fly for PSA?
I just quit PSA to fly for Eagle. Morale is rock bottom. Schedules are horrendous. They treat you like dirt. Upgrades are non-existant. Unless you have to be based in CLT, I can't see any reason to go.
Just so no one thinks I've got nothing good to say about PSA, pay is ok for 1st year FO. (72 hours/mo and per diem 24hr/day in training.) The planes are good. The crews are great.
But there are far better places to start your career.
