I'm flying DCA-DTW-CLE-MSP-ABQ-MSP-EWR-DCA for a MR this weekend where my flights were orignally all CO coded & NW operated, except for EWR-DCA. Then a schedule change took place & my DTW-CLE-MSP flights got recoded as NW coded & operated flights. Now I'm showing the same R fare - however some of them are coded as Business & others are coded as Int'l Business. Also, although its showing the right flight times, the order on CO.com is DCA-DTW, CLE-MSP, MSP-ABQ, DTW-CLE, ABQ-MSP-EWR-DCA. I called the NW Silver Line to change from aisle to window seats (my EUA always gives me aisles even though I have window in my profile!) and they've put me on hold (been on hold for about 5 minutes now) while they check it out because it's "very odd" and they can't see the CO coded flights.

The NW agent told me that when a flight gets upgraded, it now goes into R inventory if it's a CO ticketed flight. That makes no sense to me. I think he was just making up an answer as he didn't sound to sure of himself.
