In my limited experience (one flight today) I was able to, as a PM, select KLM EC seats for no charge. KLM's site asked for money, and I did not try calling at all. The seat assignments stuck and I took off in the EC seat I had reserved.
While we were still climbing, an FA came and offered me a seat up front, so I didn't actually fly much in the seat.
