Well, I was able to log into aa.com under the AA Sabre reference this morning. It said it was ticketed, but didn't show the itinerary. Got an email around lunch and everything is now showing up on aa.com.

The Amadeus number is showing the BA and QF flights, the AA flight before the BA flight and the two JL flights connecting to/from QF flights (The first flight, AA7398 [QF704] reappeared as well).

I was able to change the perfered seat on the AA flights on aa.com, but I can't find a way to change the QF/BA/JL seats (for those that have been assigned according to aa.com). Have tried on qantas.com and checkmytrip.com.

I have noticed that the receipt says AU$3,541.17 but they've only charged AU$3,382.54 to my account. I assume they are going to come back later asking for that extra $158.63?
