Whoa, did anyone else notice this? I just saw it while looking at NWA's upgrade policies (for another thread).

http://www.nwa.com/freqfly/travel/compan.shtml

• Effective March 1, 2005, WorldPerks mileage upgrades for trans-Atlantic and trans-Pacific itineraries are only available on Northwest Y and B type fares and Continental Y and H type fares.

Currently we can upgrade from M fares for non-China trans-Pacific itineraries. I just looked at that NWA page recently, and I could have sworn that new item wasn't there. I looked at Google's cached version of the page at http://www.google.com/search?q=cache...l/compan.shtml (which was retrieved a week ago on 11/30), and sure enough, the new item wasn't there. Looks like we've been enhanced

edit:
Hmm, it seems http://www.nwa.com/freqfly/memrules/general.shtml hasn't been updated yet, since non-China M fares are not excluded: Upgrade options are valid on most published fare types ... except for the following: ... U.S. point of sale trans-Pacific fares beginning with H/K/V/Q and H/K/V/Q/M for flights between the U.S. and Hong Kong/China ...
