I am going to be in OSL in May, and I am wondering if there is a lounge I can access. I am Plat. Elite on NW, and a WorldClubs member, flying OSL-AMS-MSP-SJC booked in Z on NW (but the first segment is Z on KL). I know that KL has an arrangement with BA to use their lounge in OSL, but I don't know if that's just for KL members, or if flying WBC on NW gets me in or not. (The OSL-AMS is in Z, but I am suspecting that is "Europe Select" or whatever they call the intra-schengen business flights.) Anyone know?
