US airlines have a separate F cabin with better seats. These seats are sold as F and the unsold seats (most of the seats on many flights

I think there is more to it then that. Last week I was on a flight from CPH to AMS and the C cabin was empty. Smallest possible C cabin is still 5 rows of seat mostly.
KL just doesn't want to devaluate their C seats. I asked about the OLCI ops then they only take place when a flight is overbooked. There can be 5 Plat Elite's on a flight, but if Y isn't full they don't get the upgrade to an empty C class cabin.
It just a total difference approach on handling your FFP Elite's.
