To the two posters above, it has always been a great mystery why you by the Cx codeshare on many partners' metal (flights to mainland China come to mind), since historically they're more expensive, yet don't offer CX lounge access or MPC Miles.

However, with the change to Cx Club Points, might there be a change? At least the fellows picture above implies so. It'd make a lot of sense if so....encourage you to buy the codeshare. Just i won't be the first one to try!
