No other logic applies.
Apart from the logic that asks the question "will this route actually make any money".
Stobart are a trucking company who have got into airports - that follows logic to a point.
Connecting those airports just because they own both of them sounds more like the economics of the mad house to me, and the fact the council want it doesn't mean it is going to work either.
Equally, the airport / airline attempt at vertical integration is often tried, seldom a success.
