If you do a search, you will find previous threads here in which it is
shown that the RTW REWARD options are not very economical.

While a PAID RTW is a cheap method of flying, and is usually cheaper than
a simple America-Asia round trip, a REWARD RTW is usually more expensive
than various reward round-trips.

As I wrote in a previous thread, for ALMOST the same miles as a RTW
reward, you can book 3 return reward tickets that would in effect give
you 2 RTW trips instead of one.
