I need to book a NRT-BKK-HKG ticket this August. I bave mileage on all the major programs, except DL. From what I can tell, the ticket will cost 40k miles on AA, 25k miles on CO, 20k miles on NW, and 20k miles on UA. However, after a few tries, there seems to be little availability into BKK. Does anyone have any suggestions on how to proceed?
