Update:
I just got off the phone with AA RTW office. After I told the lady where I would be departing from she laughed and said that she had been booking a lot of these tickets this week.
I had all of my flights, departing date and the continuing (fake) dates ready and the entire process took about 15 minutes.
She gave me a confirmation number and said she is sending it to the rate desk for the taxes and carrier charges. The base rate I was quoted was $2,389. The next step is that I call back tomorrow to find out the total and they will hold the reservation for me until Friday 8/5.
Here is my DONE4:
MPM- xDOH-SIN-(SIN- DPS surface sector)DPS-HKG-MNL-SAN-YYC-SAN (SAN-LAX surface sector)- LAX-LHR-BUD-LHR-JNB
When I confirmed with her that I could change the dates, she made the comment that it would be tricky because this is a discounted fare and therefor there would be less availability. Has anyone had experience with date changes? I am assuming that you book it as soon as the calendar opens up...or at least as soon as you can.
This was really easy. So, either they are going to come back with reasons why it can't be done OR all of the help an input I got from you all made it work.
I'll keep you posted! Thanks all! And a big thanks to pandaperth!
