Just as a reminder, if you get the HoKeY speech to Asian destinations, and you really want (need) to go business class, have the agent check out fares to your destination on a WHOLELY NW ticket (NOT A CO CODESHARE). Most NW tickets are upgradeable at substantially lower prices than CO. For instance, a short trip JFK to HKG is $1,000(JFK-BKK upgradeable is also $1,000) upgradeable on NW but $1800 on CO.
All NW upgrades to Asia, except HKG, require M class or higher ($1,000 RT to BKK). HKG is special and requires the next highest above M, I believe B, but am not sure, and this works out to about $1000 as well.
In the situation where you are buying a ticket and upgradeing with miles from your OnePass account, CO WILL sell you a wholey NW ticket upgraded on the spot. I am holing two of them right now.
