Flybe should be considering to extend the Belfast-Manston service to Ostend-Bruges in Belgium. There are no direct flights to Belfast from here.
Flights would attract cross-channel traffic aswell as business and tourist traffic between Belgium,Kent/Southern London and Northern-Ireland.Same for Edinburgh-service:extend to Ostend. Or make a small hub at Manston with some scissor-flights e.g.Belfast-Manston-Ostend combined with Edinburg-Manston-Jersey.
Even the Manchester-Manston service could be economically sustainable if seen in combination with traffic to Belgian coast and Bruges-Ypres/Flanders,etc...Grtz
