I am in the process of purchasing three AONE3 ticket originating in Cairo. I have had the itineraries confirmed for several months and set up for ticket on departure. I received a phone call from AA RTW desk on Wednesday informing me that CX has cancelled all our segements and availability is no longer available. After speaking to CX, I discovered that CX sends a msg to AA informing them that CX requires a ticket number before "X" date otherwise they will cancel the ticket. If I cannot purchase these tickets prior to getting to Cairo, what can I do to ensure that CX does not cancel out our CX flights?

I will cross post this in the AA forum but want to make sure the oneworld experts see it.
