Yes i know raising the finance for a startup airline is hard at anytime, but i can see a carrier with six Boeing 787 ,s flying non-stop to west coast USA, HKG, and competing with the incumbent airlines to New York, Dubai etc.
Take off and landing slots are far easier to come by at MAN than LHR and as regards ticket prices a new start up carrier will be able undercut the legacy airlines.
A little birdy tells me that Zoom UK may be looking at expansion at MAN
