This is bookable as an AAVacation too for only a couple bucks more ($690 for the dates in your example). Routing is slightly shorter BOS-LAX-HKG-NRT-BOS but EQD/RDM earnings would be a lot higher. If my math is right it's 18414 EQM, 1,841 EQD, 9207 RDM; compare to 19775 EQM, 563 EQD, 6193 RDM buying the ticket by itself.
