IIRC, when they had that slide up today, the Neg Comm Chairman said something to the effect of "If our current contract requires 10,000 pilots to do all the flying for this year, then under this agreement it will require 9,992 pilots for 2017, 9,992 pilots for 2018 and 10,014 pilots for 2019. The change in 2019 is due to the additional bump in vacation value. This is why we characterize this deal as staffing neutral."

Not a direct quote, but I'm darn close.
