You can use them as an indicator, but the buckets are different, and not visible. Normally, if there is Z availability, there will be upgrade availability, but not always. There is no way to see for yourself online if upgrade inventory is available. The only way is to call FB. If you're seeing plenty of seats open in WBC, chances are good they will release upgrade inventory, so keep trying.

FYI - upgrade inventory on NW is very, very limited for FB.
That information is yet another misinformation floating around.

Flying Blue has very clear upgrade policies for travel on NW metal.

Transatlantic upgrades from Y class book into Z class
Transatlantic upgrades from B class book into D class
North American upgrade from Y and B class book into R class
