I got extremely bad value because it was a redemption from South Africa, where the taxes and surcharges are around $400 on a $750 ticket (rough conversions from SA rand, it's in the ballpark).
HKG-BKK in F for 39k miles seemed like a better deal (with $15 in fees), but I don't recall what the revenue fare was at the time.
