While you might have to wonder about Flybe signing up to such an agreement, it is hard to believe that a small provincial UK airport like NWI with a less than exemplary record in fostering their commercial aviation development, would really go down this route to screw the only airline that is interested in trying to make a real go of operating 'from the back of beyond' !
A few years ago I used to fly for a small company which was also forced out of NWI operations by this sort of stupidity ... do NWI want to develop or don't they ?
