Couldn't BE just extend one of the Q400 flights to EXT to/from NQY and feed its EXT flights that way with NQY pax? That is if they can schedule the departure of flights from EXT to places like MAN, GLA, EDI, LBA and BHD for more or less the same time (most of them seem to be at 2 pm'ish). As Flybe offers connections, it would not be that complicated to implement, I guess. Times for NQY would not be terribly convenient as far as early morning and late evening departures are concerned, but still better than nothing.
