On AA, there is a difference between North Asia (Asia 1) and South Asia (Asia 2). If you go to South Asia by choice, a coach ticket is going to be 40,000 miles.

To answer your question, the only places that CX flies in Asia 1 are Beijing, Seoul, Tokyo, Sapporo, Osaka, Nagoya and Fukuoka...all of which will be served by JAL. So the bottom line is that you either need to pick up 15k more miles, which shouldnt be impossible, or just fly somewhere within the region on JAL.
