The PBS language as written will force PBS down your throats. The final paragraph allows the company to claim operational necessity, and they will, and the arbiter will consider that per this LOA.
It's not just the $5M to $7M it eliminating the conflicts to get more utilization from the pilots, to get more flights done. You bet you *** they'll claim operational necessity. The LOA also says the intent is to implement PBS which again favors the company. Much better chances arbitrating an almost decade old never implemented PBS LOA where the company didn't perform either.

Demand the right to a pilot vote. Threaten a DFR lawsuit if not for the significant changes to the work rules and compensation.
