Thanks for all the replies. I am redeeming CA first via a lifemiles award (not purchased yet), which does not allow mixing of classes. The other issue is the ferry, which I am not a big fan of. So that is why I thought the best way to get to Macau would be this connection. The other choices are via NRT or ICN, but they force an overnight. My idea is to get the CA ticket and then call and see if they can merge a Air Macau ticket. If they can then I would purchase the air Macau ticket and let them work their Air China magic. Thoughts?
