The $100,000 bonus is most likely a new hire bonus and thus not in the contract or subject to retroactive pay. Envoy specifically states that their $100,000 bonus for 950+ hours of 121 time is for pilots receiving a CJO between 11/15/22 and 12/31/22, and beginning class no later than March 1, 2023, so I suspect the terms are the same at Piedmont and PSA. I am sure there is a catch, like a three year commitment or something.
