By the looks of it, all Flybe flights to EDI and NCL are to be operated on the EM4. I would have thought the DH8 would have been a cheaper option for them. I wonder how long this is planned for, as the EM4 didn't last that long on the BHD and CDG.
Cheaper.....definately, available.....unlikely just yet. Flybe have cancelled their EDICDG service which was operated using the 145. With this in mind they have crew in EDI to fly this aircraft and so I guess they will use this in the short term until the fleet renewal programme sees this become a Q400.
