Check MSP - CGK (Jakarta). I'm seeing it for $875 with AA flight numbers for one direction NRT - CGK but not the other (if you can find AA flight numbers for both you'll get more miles).
Comes out to 18191 EQMs (or 18523 with 500 mins). 4.8 CPM and chance to use SWUs if you have any. Same day turn is possible (well you arrive 2 days later at 1am and leave that same day 630am)
