Sounds good however-- how many from Aberdeen would choose a flight that stops off at Leeds on the way to Heathrow? Would they not prefer a direct flight with BA. It is bound to be shorter in time. Even trying to match the existing arrival times would mean an earlier start if going by LBA , even using jet equipment. Also how many would use the ABZ to LBA sector? Not many -so how many seats need to be reserved for the LBA to LHR sector, thus how many empty seats on the first leg to LBA?
