The new reserves required formula is a huge win for line holders. It now allows them to swap out of the crap trips and leave those in the pot for reserves to fly. As a result the trips in the pot are less efficient and as a result utilize the reserves less, meaning that there is less likeliness that the reserves will time out or break guarantee. The trips being flown have less credit, and less block. The line holders are now able to dump these for better trips in the pot.
Will it effect staffing in the long term? I do not know, but the utilization of reserves is now where the company has been targeting for a long time. Line Holders are happy because they can better their lines a lot easier, and dump the horrible trips. My guess is that the company will want to keep the way the new reserve required formula because it allows the line holders to get more of what they want and that being 88% of the pilot group it is a win. The benefit for reserve pilots is that they can swap off days to better their schedule too, the downside is that the trips flown will not be of the same caliber that they used to.
