Have you considered getting status on OneWorld as well as * Alliance?

If you travel a lot to Asia, the cities and routes you frequent the most will dictate which airline makes the most sense to get status on. For instance, if your base is HKG then you'll really want Cathay status (even Silver @ 30K status miles gives you lounge access). If you travel to MNL the *Alliance is pretty useless as you need to take crazy routes to get there and still earn status miles. If your base is BKK or SIN then *Alliance makes sense.

BTW -- I find Air Canada just as good as CX, SQ and TG crossing the Pacific when travelling in J.
