It won't be easy for Norwegian to establish themselves in any long haul market, however I believe that their brand new aircraft, reasonable product and most importantly a low cost base in comparison to many long haul carriers could make them an appealing alternative to the norm. That is also why I feel they could make a better job of a JFK route than the other mentioned airlines in S1E's post. I'd say after BKK we could see HKT and possibly FLL introduced however these would ultimately rely on how the former performs.
