Hi, -- I commute 3-4×/year roundtrip between BKK and BOS. I've been using OWEs for well over a decade, but I've just started reading about Circle Pacific fares, which could be significantly less expensive for me. On a very basic level, my understanding is:

1. I can use them between SEAsia and North America.
2. Both ocean crossings must be TPAC.
3. One crossing must be northern, for example JFK/HKG.
4. The other crossing must be southern, for example SYD/JFK.
5. The fares are mileage-based rather than continent-based.

Have I missed anything significant?

Thank you all in advance for your assistance.
