If the OP's connection to Oslo is on KLM or another SkyTeam carrier, they'll have access for their AMS-OSL leg. If not, then they only have access on the return (AMS-JFK).
Yep. SkyTeam for both ends of my AMS connection. DL into AMS, and then KL from AMS to OSL.
I called KLM today, and no one could tell me why the KLM lounge site says I don’t have lounge access on my ticket.
