In Reply to: Thanks, I had a look at some dates posted by gunn parker on Thursday, 25. March 2010 at 10:56 Bali Time:
on a flight in Jan but was able to change my booking on AA website up until a week before the flight!
So there is no hurry to change!
If you do a "No show" you can claim back your taxes,in my case (thanks to a forum member) the taxes were more than the actual flights and the change over for 2 tickets to another date was $305AU.
I just waited for another special and got my taxes back!
