Thanks!
No, a North America to Asia 2 award cannot transit any 3rd region except Asia 1. SIN-DOH-BOS is bookable with AA miles, but it will require 2 awards, SIN-DOH + DOH-BOS.
Thanks - I was afraid of that- That would mean 110K vs 70K or so if I flew via Japan Airlines for example... Doesn't look to be worth it - Although if the availability is there...
