I would expect Flybe to announce new Aberdeen routes in the near future, possibly in time for the coming winter season.
I would bet money on Birmingham and Norwich.
Flybe are evaluating both Humberside and DSA. no decision has been made public as yet, but one of the two will become a Flybe destination. Unfortunately, my money is on DSA for EDI, GLA, BHD and regional French routes.
