That was the purposed idea, as brought by SH in Ground ( I know BS ), but he stated that with PBS there would be no need for integration days due to the fact that it should take care of transition pairings from month to month. This, to me, would add to quality of life because you now can actually plan to have a life as a line holder on the first 3-4 days of the month. They would in turn need more pilots to cover the pbs schedules, which should bring a few back. Agreed it's a stretch, but would that be something you might be interested in ?
