A flyBe v2 looks to be on the horizon, and with confirmation of an Operating Licence and the bmi slots at Heathrow there are pieces falling back into place.

An airline which specialises in regional services from secondary and tertiary cities could be a compelling plan, serving communities too small for the larger low cost airlines, with smaller efficient aircraft.
