SIN and HKG tend to be the best options to Asia...SIN can usually be had for $1100 ish and sometimes is sub $1000. HKG can be as good as $800, but typically is more like $1000. Still good deals on both once you factor in some good routing.

SIN is usually your best option not only for the extra miles, but it works out to be a same day turn (6 hours in SIN) with some creative routing (ie through GUM and HNL on either outbound or inbound). Even getting only marginally creative in the routing puts you at around 20k miles for typically in the 5.5 cpm range. It is however, a brutal run (particularly if you don't have decent status and won't get the intra-Asia CPUs), as it's basically a 4 "day" trip with no stops (although you'll typically have at least 12 hours ish somewhere along the way back for scheduling)

In fact, I'm actually on this exact run right now that was originally 21k at 5.2 cpm, but due to a bit of IRROPS and a couple of nice re-booking/SDCs into Y, has now become an attractive 23k at 4.7 cpm

If you can stomach it, YEG-SIN with some crazy routings (the island hopper even works sometimes for the particularly insane) is always a solid Edmonton MR option. I almost always do it once a year to keep 1k.
