I also managed to get a QF business award seat 330 days out.

I just finished the award, as it happens. I'm really amazed that it was so easy. I first picked the cities to visit and a routing and dates I wanted. The idea is to purchase a circle pacific for myself, and use an award for my partner. I started calling AA 330 days before each flight, and to my surprise I was able to book desired flights and routes every time. I did have to adjust the dates a bit, by a few days earlier or later, but that's all. (I was in Prague last week, and called the U.K. AA office from there, and they were able to add more flights as the 330-day window opened for each.)

We're going AA: SAN-LAX, CX: LAX-HKG, QF: HKG-SYD-BNE, QF: BNE-CBR, QF: CBR-MEL-AKL, QF: AKL-LAX, AA: LAX-SAN. (I like HKG-SYD-BNE on QF rather than HKG-BNE on CX or one of the other routes on CX or QF to get a 747 upper deck.)

My advice is to keep calling.
