Jet2
last time they tried pax flights from BOH it was to Belfast INTL and although load factors were not terrible (80% in Aug 2005) the yeild was probably lowish. I think that a 4 weekly service by easyJet would work. The market is around 55-65,000 pax per year and a big name is required to tempt people from flyBe down the road.
Maybe Jet2 wanna try a different route or two? Will be a welcome return if they do...
