This promotion is only valid for AAdvantage members who purchase and fly on published fare tickets booked in J, D, I, R, Y, B, H, K, L or M.
The cheapest economy fare is about $958, but it books into O so it won’t earn you the bonus miles. The cheapest qualifying economy fare that will earn you the bonus is $1,750 (it books into H).
Business class travel (if it’s in your budget) is a better value. You can find qualifying business class fares (book into I).
