Probably time for Manx government and/or the local businesses to come up with a local solution just like quite a few marginal destinations in other countries have. Stuff like all those "XY-flygs" in Sweden, "Alsle" in Denmarkt, "Peoples" in Austria or "RNA" in Germany that provide links to the nation's capital by either running a small local airline or selling tickets for flights operated on their behalf by an ACMI-provider..
