Flybe only operated Dash Q400s, BAe 146s and E195s prior to the BACON buyout. All the BACON aircraft will be phased out over the next 3 years (or so the plan goes) and replaced pretty much one for one with Dash Q400s. The E195 is being phased in as the BAe 146 is phased out.
Without digging out all the guff, I think the final fleet makeup is intended to be something like 66 Dash Q400s and 14 E195s. We already have 31 and 3 respectively.
