I know Ireland has the cultural ties to the USA, but, as Ray has said, if you had asked to predict which UK/Eire airport would get the first trans-Atlantic flights outside LGW by Norwegian, Cork would have been close to bottom of my guess list.
It has no Tatl nor historically to see trends, it has no Norwegian flights currently, and there are markets that are much larger that could do with the flights.
It just shows you cannot second guess Norwegian, and it shows that the potential Norwegian long haul guess list from the UK and Eire has been blown wide open.
Previously I would have said BHX or EDI were the obvious choices, but Cork has shown that it appears an airport doesn't even need to have Norwegian flights to be considered.
On the Manchester thread, I have posted that the Norwegian beta site is saying MAN-BOS starts May 14th, but no flights bookable yet, so, who knows where the Norwegian dart will land next.
I had previously accepted that Manchester was a glorified football flight destination, but now, I don't know, as I said, this has just blown wide open!
