The fact that the NYT thinks that Norwegian will be flying from EWR and that BCN will be a new routes says enough about the integrity of that article.
Of course it's possible, still think it's the most viable option for the moment.
We don't know what Norwegians tactics will be. They may well try BFS as a test for the market. They are also one of the only airlines willing to do 3/4pw Transatlantic to the East Coast. Most other airlines is 5pw+ or no route.
