As much as I dislike the tone of Rivet Joints post, he is right in a way that BOH and business orientated routes just don't work. Leave those to SOU.
But they did work from Bournemouth, that's the issue. Flybe got some decent loads in the first year with little advertising from the outset. BOH didn't impact SOU's loading either so it proves that there is a market there. With the economy picking up and if Flybe gave it another year they would have seen even better loadings. FR and Thomson are seeing loads in excess of 90% and decent yield too.
Flybe only flew from BOH to screw SOU for a better deal.
