As all of you fellows suggest I should use asia miles, I am looking at their website and find out more interesting things.

Asiamiles require more miles for upgrade like from Y to C, such as the segment LAX-HKG, look at the award chart award zone should be D, actual miles 7248, need 35,000 for one way upgrade, roundtrip a little lower 60,000. Whereas compare to UA, US to Asia is 25,000 one way, AA is 25,000 one way too but only limited to Japan from US. So concluded that asiamiles need 10,000 more miles compare with its competitors.

Quite confusing about the miledge calculator and the part how to earn the miles. Put down the segment like ORD-NRT and select discount economy fare, both AA and JL only got half of the miles 3129 out of actual miles 6274. But when I go to see how the partners of asiamiles get the miles. From the Terms and Conditions, It said the classes Y/B/C/G/H/K/L/M/N/Q/R/S/V/W/X in AA earn 100% of the miles, 50% not applicaple. On JL only Y class earn 100%, and Y/B/G/K/M/N/Q/W/X only earn 50%, so that is true as what the miles calculator said.
Is it they didn't update the information for AA, or just something wrong ?
