Ever since CO implemented some online booking changes this past Wednesday (3/10), I can no longer find NW-operated flights from their booking engine. I went to NW's site and correspondingly cannot find any CO-operated flights.
I remember both websites offering each other's flights. I am trying to book a flight from YYZ-SFO and would like to do so from CO's website. However, I'd prefer flight times from NW for my outbound and CO for my inbound leg. The only way I can get this combination is with expedia (which I prefer not to use...)
Anyone know of anything about this?
