Last time I was flying KE in Y and tried to access the NW lounge with my NW Gold status (Asia-based gives WorldClub access). The lady gave me a hard time since I didn't have the actual card, but eventually relented after talking to someone on the phone about it. Would I have been able to access the KE lounge also? Might fly HND-GMP next time, but no NW lounges there of course.
