Unfortunately Jet2 have been suffering from problems with the 757 fleet, but it happens to all airlines. The lauch of such a route, like NYC is a very complicated process, particularly when a/c need ETOPS approval. I am still not convinced that such a loco route would work from NCL, if it did start then hope it wouldn't go down the same route as GSM and their longhaul programme.
NCL still holding out for CO!
