Skyman and Dumdumbrian to get pax through the doors you need to get the airlines in to offer the destinations, to get the airlines in they need to be convinced that the pax are there. It is a vicious circle but it isn't that clear cut there are things the airport can do to try and attract the airlines such as providing a parallel taxiway, building a new terminal and providing airbridges etc. The airport has to do everything in its ability to tip the scales in its favour and at the moment it doesn't seem to be doing anything to help itself.
Skyman the airports biggest single comercial user is FRA which as it happens is GA. They provide more business than any of the airlines at MME. Yes the beneficiaries for the moment will be GA but as I say above the parallel taxiway will aid the airports ability to attract airlines.
