There not going to get you to vote the SAP away, anything you vote on will have a "SAP" according to the words on the paper.
What will happen is the SAP pot will look like it does after FCFS, using a % of block hours won't work because the company will methodically go though a make sure only complete garbage trips are included in the % of reserve block hours.
As the other poster said trip splits for training and vacation won't work because PBS monitors that when it constructs your line.
You also have to remember these are off the shelf products sold to airlines.
So you can write multiple PBS rounds, and reserve block hours into a contract with good faith, but since anything would be brand new it would require heavy programming and meanwhile the union would be enforcing it as well as they have done with CCP.
This pilot union has a track record of coming up with grand ideas that aren't able to be enforced as written, namely the concept of active captians, instead of a straight % of the seniority list, then there's CCP as mention above.
Why would any one want a union who can neither define, or enforce "active captains" to have a finger in drafting your monthly schedule for the rest of your career here.
All we heard from the crew rooms about the flow deal was we got over on them because the "captain snap shot" included everyone, which now smells like a load of BS.

And for the record, I am proud of the efforts are union guys are putting forth. I just think, since somehow, we keep getting screwed between what we expect will happen, and what does happen, the most reasonable thing to do is tell them to go pound sand until section 6 opens in 2023. Getting straight gains is one thing, but getting into contract rewrites is playing with fire with these managers, no matter how proud you are of any improved "soft pay package"
