[QUOTE=Carfield;37098765]No the new NRT flight is considered operated by Hawaiian Airlines, so JAL will not recognize your OW Emerald status.
You are only allowed to use the Sakura Lounge, not the JAL First Class Lounge.

Another poster (I think in the AS thread) mentioned that their BP for SEA-NRT had "Sapphire" printed on it even though it was of course a HA operated flight.
