Let me start off by staying that I love flying, so what I'm looking for will often be more imaginative than what others desire in their itineraries.

So yeah, absolutely, this is not a viable itinerary, but for all those who believe that booking Singapore First is completely impossible or that ANA Suites are out of reach. Here is an itinerary with both, for less miles that it would be for just the NRT to HNL by itself (85k miles).

Ultimately, I found this itinerary because I do need to get back to the states from Australia. What I ended up booking is Perth-Singapore-Tokyo-Hono in J, J, and F. This is the same price as a SYD-LAX saver fares in 6 across UA business class that people are so eager to snatch up (or only 60k if I kept the last segment in J). I'll catch a cheap revenue flight back home from Hono.

Brisbane is another interesting proposition for Australia travel. AC is the only North American *A carrier to fly there (with arguably a better hard product in J than what UA sends down under and better saver availability). So from BNE, I could fly back to the states for 90k on AC via YVR or I could fly to Hawaii via YVR for 60k. That's just nuts to me! I love being in the air so I'd easily choose to save 30k miles to spend a day in paradise and catch a revenue ticket back home from there.
Additionally, I'm planning a whole southern hemisphere excursion, so I booked SCL-YYZ-YVR-BNE on AC, all segments in J for 90k United miles. It costs 80k for just a Southern South America to North America award. Why not spend 10k more miles to see Australia?

I know people love to complain about dynamic pricing, but if you enjoy flying and don't start or end in North America, there are still deals to be had.
