If you mainly want to earn miles for later OW award travel, then another alternative is to fly JAL to Bali and earn AA miles. However, discount fares may only earn 70-75% mileage. Y fares are 100% and biz gets you 125%.

Btw,a couple of years ago I used an AA award on JAL to fly to Bali and my girlfriend went on a paid JAL ticket and got AA miles. Bali was great! Take an extra large suitcase (or two) for souvenirs! I kid you not. We shipped a large crate home! Don't do that, it was not cheap by the time we paid all the agent and port fees here on the east coast U.S.
