Thanks Superking. I guess what it comes down to is finding out what availability will look like to non-peak Brazil and peak Australia.
I was playing with united's redemption about 1 month ago looking at various availability to Brazil for a November 2012 as a comparison. It seemed like there were many available sports for the saver awards. However, this was still based on 6 months prior, so I guess playing around with AA and UA later this year may give me a better idea about next year.
