Does ExpertFlyer currently display the current World Business Class upgrade classes for NW and KLM flights? On KLM-coded flights, B inventory now upgrades into the
D bucket. And on NW-coded flights, B inventory upgrades into the
U bucket.
Also, I am still not sure: is waitlisting available for World Business Class mileage upgrades from B (and Y fares) on NW flights? On KLM flights?
