Just because you see a 3 man roster (or other changes) doesn't mean anything is getting done. Wonder how many of these will actually be flown with the folks rostered to do so (or at all).
How efficient is a perennially unstable roster ? How efficient are multiple changes today only to create 4 gaps in the roster later in the week ? How efficient are wild swings of flight time into overtime and people being sat because they time out (or PXd home) ? How efficient is seeing (legitimate) unfit days go from 1 or 2 to 35 (that's a month of lost productivity on top of everything else). How efficient are last minute ASR-Fs from body clock swaps ? How efficient is phones that ring unanswered or PX/PTing everyone all over the place ? How efficient is burning FTLs on reserve ? How efficient is positioning someone who lives in Vancouver but LA based on reserve from LA back to Vancouver (and giving them a hotel room and allowances) only to operate out of Vancouver later ?
THESE type of things could have very real productivity gains.
