Honestly? Being AMS based, transferring at CDG usually doesn't make sense, especially when flying to smaller airports in the USA that already require 1 transfer at an American hub. And everything else aside, when flying Y the free upgrade to Economy Comfort with KLM does hold some value as that extra legroom is noticeable.

If Air France does roll out Economy Comfort as rumoured, that would help on a few of my regular routes to Asia where I'd gladly take the CDG layover (and sometimes already do based on departure times).
