There has been a post by somebody here (2 weeks ago?) indicating that OK+ had sent them a newsletter or something that indicated CZ flights would fully accrue miles since tomorrow. I am a member of OK+, but haven't gotten around to switching to the e-newsletter, and the website doesn't say anything.
I think it's a good bet to say that China Southern will be a member of Skyteam effective 01/11/2007. ^

By the way, the earnings SU have posted for CZ are little short of pathetic!!! 30% COS for business??
