Routing is SEA-IAH-NRT-IAH-SEA booked on Continental's web site.
Continental automatically upgraded SEA-IAH and IAH-SEA.
It is booked as Continental Flight CO7 IAH-NRT and CO8 NRT-IAH in B class.
If one were to Book thru Northwest's web site it shows flight # is 6007 and 6006 operated by Continental.
I have heard through the Mileage Run Forum that you can also upgrade with 30,000 miles roundtrip.
Anyone have a definitive answer regarding Platinums can use SWUs (preferred) or Miles to upgrade these flights to Business Class and how soon you can do so.

Travel can be on Northwest Airlines or Northwest Airlink flights numbers 1-1999 or 3400-3699 as well as KLM flights number 1-999/6000-6900.

Looks like can't use SWUs for Continental 6007 or 6006.
