My guess is Winter this year
I have no specific info from the inside other than as a line pilot I know the majority of FO's/SFO's I am acquainted with and a moderate % of Captains have been polishing their application forms for BA. As other carriers open their doors too this Winter I would expect an significant number of current Flybe pilots to apply to Easy/exec jets/charters etc.
On this basis I think it highly likely we will be reopening the doors to recruitment this year, however I wouldn't expect many DEC's because there a huge number of command ready FO's already here so expect recruitment to be FO level only
