EWR-DFW-NRT-BKK-NRT-DFW-EWR is ~21,300 miles and shows as $784 / 3.7 cpm

Disclaimer: this prices out on ITA, but a quick check for random dates on aa.com shows the price but then throws up error messages when selecting the itinerary, so this may take some patience to book as is sometimes the case with AA code-shares on JL.

Even better on JAL
 

JL 788-operated JFK-NRT-BKK for $680 a/i. Itinerary I pulled up on aa.com was AA-Q, AA-S, JL-N, JL-N for each of the segments so only 50% qualifying points.

Any sample dates?

I think JL N only earns 30% to AA

Yep.

I'm going to CGK with JL and found that out after the fact. No matter, as it's a good fare (as opposed to a mileage run).

Filter american on google you can select the correct codeshared segments, for example aug 31st to sep 14th. Then you're getting all american codeshare, codeshare gets 100% miles on even the jal flights. That's 758 i believe. The price shows correct, don't know if it's buyable or not
