Although AA miles do expire after 24 months with no activity (earning or redeeming), it is very easy to earn AA miles without flying. Any such earnings would automatically extend the expiration date of all AA miles by an additional 24 months.
I purchased roundtrip tickets for JFK-BOS-NRT-CGK on AA+JAL through Amex IAP. I'm just wondering where should I credit the miles if I want to use them in the future for travel from NYC to Asia in business class.
