As I am currently in Thailand I got the # of the local office from AA's website & after faxing a copy of the paper ticket the very helpful person I talked to changed the flight (3rd on my RTW) to May 1 just have to change it again when I know the date I wish to fly.
Am very happy with the service from AA both at Pearson (YYZ) where I originally booked the ticket + here in Thailand.
Thanks all for the advise.
