NQY-MAN with easyJet and Loganair both on it "underserved"? Interesting notion. easyJet are summer-only and the old Flybe service was supported with their own hub connections at MAN - none of which they have today. Jury out on that one.
And NQY-LHR will be up against an operation at LGW which is both subsidised and free of APD. Maybe during the peak summer, but during the winter may well prove to be a different ballgame.
