The bonus is 10k unless you have 1000hr of previous 121 experience and then it is 15k. The email we received mentions an "employment agreement" but no details on what that means.

I mentioned this before but even with a 10k bonus, first year pay is still below compass, endeavor, Gojet, Skywest, expressjet, republic, and trans states. Also without the bonus your second year pay at PSA will be less than your first.
Add to this PSA has a terrible contract, which they are presently violating with critical pay and no commuter hotel for your most likely 2 leg commute to Dayton.

PSA can't get new pilots in the door so that means no upgrades, you will be stuck on reserve, again in Dayton. They can't staff the airplanes the have, they have deffered airplanes they were supposed to receive, and more pilots are leaving than being hired each month.

Don't be fooled by the propaganda in the ads

There is No Growth
There is No Stability
There is No Incentive to come to PSA (except maybe living in base)
