Hello,
After looking at my booking, I called the DM desk. dl.com is WRONG...there is a charge (albeit at a discount) for DL Medallion members. KL is willing to sell me an EC seat on their metal for a 50% discount...
From
klm.com:
Price
The price for a seat in the Economy Comfort zone is from EUR 60 to 150 per one way, depending on the duration of the flight. If you are a Flying Blue Platinum member or if you travel on a fully flexible Economy ticket, you can get a seat in the Economy Comfort zone free of charge. Flying Blue Gold members and SkyTeam Elite Plus members of our partner airlines receive a 50% discount. Flying Blue Silver members pay 25% less. All you need is a credit card.
