I'm surprised to see people liking the AMS lounges. They are just mediocre. At least the AF LH lounge at CDG has a Clarins Spa with free treatments. And a much better alcohol selection with usually a very nice Champagne.
And no one has mentioned the First class lounges? AF's Premier lounge is super nice with luxury cars to drive you to the plane. I'm thinking of trying KE F on the A380 with a transfer to a 777. What do they have at ICN for First class transit passengers?
