The other reason Scotland-MAN died was that there's almost no feed in MAN. Business Air were Lufthansa feeders, Loganair had their own mini-hub and BA fed European bound passengers from Scotland via based fleets at MAN/BHX. Lufthansa now serves both GLA/EDI on their own metal, BA were beaten in the regions and what was left of Loganair's original hub was killed off when BA closed their MAN base. Not sure Logan have the critical mass to make MAN work as a hub given the current environment sadly.
Of course flybe flew the routes when they bought BACON but God only knows if they were worth flying by then....
