UPDATE!!!:
I just called yesterday to see what is my new E-Tix nos as I haven't received an email from AA.com yet. The agent then told me that they can't reissue the ticket as it is not starting in the US??? They said I have to sort it out at the airport??
They said there are no changes to the ticket nos.
However I told them I have a flight this week, and I asked them whether I can travel on the exisiting tickets (on a QF flight). The agent said YES and QF will "sort it out"
I am not convinced at all whether I can travel at all and whether my coupons have been VOIDED?
Are there any tix expert out there that can shed a light on this?
SO WHAT IS THE PROCEDURE in date changes?????
