I must say that I am mildly disappointed at KLM's handling of the introduction of Economy Comfort seats. On AF Elite+ members can get preferred seats for free (heck, that's one of the few alliance wide benefits, right?). On KLM, you seemingly just get a discount - unless you are a Flying Blue FF.

Has anyone tested these seats? Are they worth the 60 EUR (or 120 EUR if you are not Elite+) one-way that the airline asks for?
