Where are you starting from?
I would suggest UA or NWA to NRT, and NWA btwn NRT and MNL.
If you are at a CASS participating airline, you could try CO via HNL and GUM, but those flights are often full and have pilots in the j/s. CO has a pilot base on Guam.
Most freighters departing the US would pass through ANC. I am not sure how the post 9-11 rules affect j/s on cargo flights. That is something we are working thru at my new airline.
Good luck.
