Which begs the question - why has Loganair never done that before? Maybe because they don't feel it is worth the effort? Citywings chased them off the rock within ten weeks when Loganair tried BHD and BLK a couple of years back - despite the superior aircraft, better brand and - on paper - the better economics of a larger operation.
To be honest, I believe that most of the Citywing routes will be gone for good unless some foreign airline with a 19 seater shows up or the routes get some sort of subsidy. Purely commercial regional flying is more or less dead.
