The airport does not need (and nor should it want) a position where one airline accounts for 90%+ of its business. It now has several airlines covering the portfolio and although there are gaps remaining like Paris (and gaps in a lot of other UK airports) then it’s got KLM, BA CityFlyer, Loganair, Eastern, Aurigny and Blue Islands all doing the job that a single airline in Flybe used to.
With the exception of the weekend French flights, all Flybe 2 is proposing to do is replicate routes already flown by others, starting with Belfast against Eastern. The airport may need many things but this isn’t one of them.
On the leisure side, isn’t there another rather obvious option which would suit the market well?
