it is depressing to look at jet2's summer offering from ncl - now that easy have started murcia, and jet2 dropped bergen, valencia, almeria, gatwick, krakow, they are offering few destinations that cant be reached by other carriers from ncl.
this is not necessarily a criticism of jet2, but maybe just more evidence that it is only the core bucket and spade destinations that will work from ncl.
This is backed up by ryanairs experience, although some posters on here seem to think they are disinterested in ncl, it is worth remembering that they have tried - olso was extremely shortlived and yields must have been poor on bergamo for that to be discontinued. if bergamo, one of ryanairs busiest bases, cant work from ncl, what hope a base in ncl??
