Several years ago, I joined MarcoPolo Club and accumulated about 10,000 miles flying around Asia but have not added anything subsequently—these miles are due to expire next March. More recently I have begun a lot of flying and have attained OW Emerald status on AA and BA. For various reasons (including more focus on Asia, my wife’s BA status, etc), I have begun thinking that it makes more sense switching my future accumulations from BA to CX. Ideally, I would like to start a new CX membership year now. However, the old membership year starts in March. But I don’t want to have only two months (Jan-Feb) to try to reach CX status. Thus it seems that crediting any miles to CX over the next couple of months would be a waste unless I could start a new membership year right away. Is this a correct interpretation? Suggestions?
