So, my wife is getting a post doc in Brisbane and I'm trying to figure out how best to get our family (me, wife, 3 children ages 11, 8, 5) for pretty cheap.

I have around 400K Amex points that I can convert into CO points at, as I understand it, 1:1. So as I read it that makes 2 business class and one economy seat. Which leaves two childs seats to buy.

We need to head out after Xmass but before Jan/10 and come home around August.

I cannot make this work on their website and the agent I called basically said "duh."

Thoughts?
