UA - NCL-EWR
I'm sure that United will have done their sums, but my concern is that at a 5 x weekly frequency, whilst I feel sure there will be no problem filling the "cheep seats" with UK originating tourists, at the front end, where the money is made, it might be difficult to fill the business seats at such a frequency.
This, as much as anything else, is what has held BHX back - and I guess, killed off Bristol-EWR.
Someone mentioned cargo earlier - the answer to that is with the relatively small capacity on the 757 it won't make a massive impact on revenues, and anyway, probably UA have different profit centres for carho and passenger.
EK, of course, is a different matter with the very significant cargo capacity available on the 777.
