Currently holding an EWR-MSP-HNL-ATL-EWR itinerary next Monday. EWR-MSP on NW6370 (CO metal, CO270) and MSP-HNL on NW809, both in NW's H class. The NW website shows both flights being in their H class (100% OnePass EQM) but the CO site, showing a separate conf. #, lists the flight as CO270 in CO I class (50% EQM). The e-ticket number begins with '012' signifying NW, if I'm correct about that. HNL-ATL-EWR on DL is not in dispute.

NW shows H class on their codeshare flight number of NW6370. CO shows I class on CO270. If I was on NW metal in H class, I would get 100% EQM for OnePass. But because it is CO metal, CO downgrades the NW H class to their own I class?? I've asked the reason for the change of class to several different folks on the phone. No one has the answer. One gentlemen even stated that I should contact my Carlson-Wagonlit office, who issued the ticket, for the reason. Why should I? I'm looking right now at my Carlson itinerary showing NW6370 in H class. Any answers from the SME's out there? Thanks.
