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?
EF supports the following hidden classes (don't worry about the Yes/No part)
Code:
Northwest (NW) W Domestic & Int'l - Coach - Award Yes
A Domestic - First - Award Yes
R Domestic - Upgrade to First for WP members and using miles Yes
D Int'l - Business - Award Yes
U Int'l - Mileage Upgrade to Business from Discounted Coach Yes
Z Int'l - Mileage Upgrade to Business from Full Fare Coach No
