Yeah, either that or CZ's program; you owe it to yourself to do a bit of comparative analysis with respect to your fare classes, their award charts, and the ability to book award tickets for others (they are very similar, but there are a few subtle differences iirc). The good news is that some awards are very cheap in terms of points required... far cheaper than DL for intra-China travel. Even if you don't fly around China yourself, I doubt you would have much trouble unloading CZ/MU points in the coupon connection.
