The main issue with PSA is a simple one and easy to fix. It’s not the pairings they build or the mothership. It’s the pairings they destroy with vacation and training conflicts. They create their own problem that could be easily solved with a union agreement. Drop the entire pairing without pay protection instead of destroying it which you will drop anyways in SAP. Either leave you without the pairing and give you the days off or add a pairing that fits within the window of the original pairing from a pairing that dropped off someone else’s schedule. It’s not rocket science and would create more efficiency for the company and better pay/QOL for the pilot group.
