The age group that fuji is talking about includes both SH and LH pilots, he isn't saying 20% are ineligible. The assumption is 20% of pilots in that age group are probably SH pilots and are therefore not eligible for VR. 20% is a very reasonable assumption IMO, maybe more.
But there aren’t any SH pilots in LH, nil-none-nada
Maybe I’m not explaining this correctly.
If an A380 S/O moves to B737 F/O is that person in now in short haul or still in long haul?
If a B737 Capt moves to B787 Capt is that person still in short haul or are they now in long haul?
