Hirsutesme,
Fair enough - I can only go by those I have spoken to (three captains and one F/O), all of whom were ex flybe. Possibly it might depend on the background of those who are leaving - were they new guys who got stitched up for training or had they flown for major airlines prior to Ryan air. The grass is always greener and I'm sure there are places a lot worse even than there. Well, almost sure anyway.
As for "There are indeed a few guys who are happy with the salary and the aircraft, but the majority are not, you only have to look at the numbers who are leaving to see that." I would suggest that could also apply to flybe as it was. Prior to the Bacon merger Flybe had huge regular resignations each winter (someone told me about 60 pilots resigned last winter, 13 Q400 captains in December alone) and the bottom third of the seniority list mostly left before they even unfroze their ATPLs, primarily due to poor pay compared with elsewhere plus deliberate policy of sending people from the South to EDI/GLA/BHD and then recruiting for SOU/EXT/BHX without letting people alread in the seniority system bid for a transfer.
It will be interesting to see what this winter brings.
