So I have a heart attack this morning and just want to share my experience. My first ever CX F award almost got cancelled without my knowledge. We were scheduled to fly out today. CX opened up the seats last second, so I changed flight. Got AA confirmation email, everything is set. Happy happy happy. 2 hours later, I checked CX.com & it still showed old itinerary. AsiaMiles.com also still show availability on this flight. Very odd. AA said it's CX's problem. CX told me I'm still on old routing, and to call AA back. AA said they don't know what else to do, call CX. CX said don't go to airport, now we don't even know who you are. Queued heart attack. 1.5 hours later, it's resolved. After a change, AA must manually re-send the e-tix # to CX. Apparently it's very common problem according to an old FT thread. AA sends the award request to CX and thinks it's confirmed. CX OTOH thinks it's a new reservation and waits for the e-Ticket #. AA system never send that in. CX cancelled the tix after several hours. You go to the airport, CX doesn't have your seats, finger pointing, and you end up with no vacation. I don't know how AA re-sends the # over. If that has to be done with a CX human being, that would be tricky during their holidays / off hours. Bottom line : When you make a change, tell AA to manually re-send the e-Tix # (obviously some agents don't know this). Always check your itinerary on partner's website immediately, either you initiated the change, or plane change. Never assume. CX.com should have your new booking within minutes. If that didn't happen, it's not going through. If you don't follow up, your reservation will get cancelled. Now I can go back to worry about the normal stuff, like what lounge to use...etc. Looking forward to my first ever CX F!
