I amended the ex-AMM DONE4 I've been planning, changing it to CAI-...-CAI. The first flight is RJ to AMM so the online tool still sends it to aa.amadeus for pricing. Price is quoted as US$7904, which looks right for the $6700 ex-Egypt fare plus taxes & fees. However -- and here's why I'm posting this, another data point -- when I give my personal details and credit card info, it fails at the very last step (as with the ex-KRT and ex-AMM itineraries reported by others in this thread).
The error message is as follows:
> An error occurred during creation of your booking. Please
> contact your Travel Assistance Desk to check if the booking
> was successful and to obtain further assistance. (9015)
I have not yet called AA RTW about this but it is now over three hours since I tried it and there is still no charge, hold or authorization for any amount on my VISA account, so I'm guessing the booking was not successful.
cheers,
