Nice routes and great that you are on AC, SQ and even TG to save on surcharges. Did you have some options with ANA related airlines from SYD to TPE and if so did you price additional distance compared to booking separate ticket?
Had a difficult time finding any ANA award availability. I actually looked and am going to fly from BNE - NRT on QF using AA miles. Fair availability for dates that I am looking at...almost every day of the week.
