Radarcontol - you've taken the thread off to one that exists already but you don't need to add the unnecessary 'International' word to the airport name. Has anyone at LBA ever wondered why they need to call themselves International?
As for the thread, RHA will probably create new travellers rather than substitute given the experience when lcc have opened up at other airports but if there ought to be some substitution for MAN as its an appauling journey over the Pennines and thats what most passengers from the region do.
