either way, I don't see it as doom and gloom as others, though I do thing EC cabins will fill up a bit more. After all, what this amounts to is a free EC seat at OLCI time for any status holder.
Still it's quite common to have free middles in front section of Air France, so I don't know that it's out of the question for KLM either.

Would be nice if middle seat blocking for Gold/Plat was honored as well.
