Realistically, the whole purpose of Stobart Air SEN operation was to put the airport on the radar of the airline industry and to use it as a guinea pig. That apparently has been successful. In general, if it would be such a great idea that airports have their own airline, it would happen every where. In reality, it is not done. Admittedly, Stobart Air (now) has a much larger footprint outside SEN nowadays thanks to the Aer Arann takeover, but in the beginning it was a SEN-airline..
