Ok to put you all straight MME is more than capable of handling a 744 on a weekly basis. They are currently handling military flights with A330, 747, 767, DC10 on a weekly some times more than weekly basis so a 744 is not going to cause a problem.
Heslop2006 MME catchment area is bigger than NCL so to argue that one is just silly. If it is advertised right by travel agents etc it would sell if it was at MME.
