Traditionally, on F+ statements, Y referred to the more expensive economy fares, not just the most expensive ones, while M referred to heavily discounted fares and very heavily discounted fares.
It looks like all flights on NW except V-class get listed as Y-class (which can lead to some nice extra miles upon retro-claiming

MLH-CDG (which is domestic, but EAP counts as international!) 1500 miles

). In my limited FB experience, they will either list Y or the correct class, in case it is only 50/25%. Even the OPUP and NW-EUA flights list as Y for me.
