Yes. And they are the fares that the underlying economy ticket must be issued in if you wish to use AsiaMiles to upgrade a CX flight to business.

Thought I'd post a follow-up to my initial question in this thread regarding upgrading on LanChile with LanPass miles. Apparently, "M" class economy fares are eligible for upgrading under the more expensive "upgrade any fare" awards. However, they are trying to charge me miles for the upgrade based on each segment rather than just for the round-trip. For example, I'm am flying from LAX to La Paz connecting SCL. They want to charge me 90,000 for my round-trip SCL-USA plus 35,000 for the SCL-La Paz segment if though Bolivia is clearly in the same zone as Chile in their online award table. Any help would be much appreciated. However, I fear that there are not too many LanPass experts who frequent this board. http://www.flyertalk.com/forum/frown.gif
