I have an upcoming flight KL651 and KL652 (in August) (IAD-AMS, AMS-IAD). I just noticed that there was a seat change, and KLM replaced 787-10 with 777. It appears that KLM added one whole column of seats to their 777, thus making it 3 + 4 + 3 (vs 3+3+3).
How did they manage to get one additional column of seats? This plane will be JAM PACKED! Is this an error, or is this a reality?
