We paid extra for "premium" and the seats were good and wide for a trans-Atlantic flight. We were entitled to use the premium lounge in Barcelona which was excellent. The flight was good with very good entertainment, but the food was very poor. Seats in premium are large and recline, but no-where near flat to try to sleep. The extremely helpful and friendly steward said "you must realise this isn't first class!" Norwegian have bought new "Dreamliner" aircraft for this route, and we disliked this much lauded plane. We both had sore throats and coughs by the end of the flight. We hated Fort Lauderdale airport - old-fashioned and chaotic and overcrowded - and the worst handicapped support we've ever encountered - and no premium lounge.
