It seems like an unfortunate side effect of the airline integration when you book a flight with CP numbers, you get a certain availability, fare class and fare, but booking with AC numbers for the same flight yields totally different information. Probably not much can be done until AC/CP begin to use a single res sys. Perhaps they could find a way to do automatic "load balancing". This would be where whenever one of the airlines sells more of its inventory than the other, it automatically is allocated more seats to sell such that the load factors stay somewhat balanced. Am I making sense?
