I reserved and paid for two tickets online from LAX to HKG for end of nov (outbound is direct, return stops over NRT). I just received a call from CS desk. Agent said AA cannot complete the ticket. The issue is that the leg btwn HKG and NRT is run by Cathay CX and the ticket couldnt complete. Agent unable to articulate a reason which was surprising (or it was intentional). Flight is available online.

I was told to rebook and figure it out myself. Not exactly the service one expects given the circumstance. SHould be a standard code share inventory.

that said, is AA supposed to honor the fare rate that I had checked out with? Any help is greatly appreciated
