LHR-JFK business Class with stop in Iceland. Checkin no waiting and Servisair Lounge in Terminal 1 comfortable. Seating is equivalent to domestic US first class or Premium Economy. IFE adequate but only about 9 movies to choose from and most were not current. Power socket at each seat. Food and wine for very good and I enjoyed the unusual selection of fresh sushi on the 2nd leg to JFK. Service friendly but not fawning. Best part of the flight was seeing our bags come off first with the Saga tags in place all ready for Customs. Lounge in Iceland was excellent but didn't have much time due to having to go through immigration just for the transfer). Price was nearly half what Air France and British were charging for Premium Economy.
