If you spotters want to play at being airline managers, you might like to do a bit of research. There are websites out there which are run by professionals for professionals which include real airports touting for business on real routes.
One of them spams me regularly, I have no association with it, but if the mods will let it pass its name is 'anna' dot 'aero'.
Neither airports nor airlines are oblivious to new route opportunities, believe me.
