KLM confirmed that my transatlantic seat assignments made by NWA agents are valid. So if you're flying KLM metal and NWA agent is confused, tell them to book in KLM system.

They also confirmed (as others here already have) no assignments possible within Europe.


Funny thing they had my gf listed for "Low-sodium" meal. I didn't ask for that during booking and it's not in her profile anywhere...
