I would go NRT-GUM and on to those destinations like YAP or PALAU. Reason is Continental Micronesia flies to those places two or three times DAILY there and has been for many years. If you get bumped on Guam, they speak your language which is ENGLISH and you don't have to mess with DEPARTURE TAXES since you are in a U.S. territory. Probably faster too. You're not BACKTRACKING as if you went through Taipei or China.
