I imagine CO have left because Heathrow is more lucrative and not because they cannot make Bristol work. I note they have just added a fifth daily flight from LHR. Once they got a foothold into LHR it was almost inevitable that they would leave at some point. Bristol, especially for those who live in the north of the city, in the is simply too close to LHR. I cannot see a full service taking on a New York route as it does fit with any other airlines business plan. Continental is the only airline that has supported point to point services to regional airports, whereas BA, Virgin, United, AA etc have always focused on the Heathrow hub. I could see Ryanair dipping their toe in at some stage...anyone for £10 fares to New York (Halifax)?
