That's a nonsense report. NCL-AMS-US, -LHR-US, -DUB-US are in place offering easy one stop options across the Atlantic. Any NCL-EWR or JFK would also mean changing to the final destination in the US. The key point in the real world, the one certain peeps need to visit, is could any operator gain enough point to point traffic year round to make it work bearing in mind a lot of travellers will continue to use other existing gateways for points and lounge access.
This is politicians trying to distort a market and "entice" an operator to start. The only two possibilities I can see are American who are currently retiring their B757s from the Atlantic, and United who couldn't make BRS, a much more affluent city, work for them. Delta have dropped EDI and MAN-JFK, so not likely to be heading for the Tyne any time soon. I despair at the commercial awareness of people, whoever they are, who write this stuff.
Summer service a few times weekly by Jet2 might be the other option, more realistic than a US network carrier.
