On any 'point to point' route there will always be those that live or have interests near either the point of departure or the destination to lend support that in some cases domestic air travel provides advantages over the train. What I am suggesting is that given the earlier comments as to the noted low load factor on the LHR - MME then historically there has not been enough support from all sections of the community to lead to growth in this service. The issue of train availability to London is largely an irrelevance in this particular discussion as it has always been available as a viable alternative. To pick up on perhaps a more relevant angle on the point of those that use the service as a convenience due to locality, perhaps such pax. are more price sensitive and will only take up seats at the lower end of the routes fare structure.
