So I am planning a trip from NY to Australia and New Zealand. Won't be traveling for more than a year so really I am just trying to get organized.

I would like to use miles/points to travel round trip in First class. I have the following balances (approximate)

400,000 - AAdvantage
200,000 - ThankYou points
150,000 - Chase Ultimate Rewards
140,000 - SPG points

My original plan was to use ThankYou / Chase and possibly some SPG to do the trip all on Singapore Airlines. This is still my preferred option for the way home. I can seem to find availability 355 days out for SYD -> JFK in the Suites if I check at the right times.

The bigger issue is the way out. 355 days out I can try to snipe the JFK-SIN portion but it will not let me book the SIN-SYD because that is 356 days out. It seems I would have to get very lucky to wait an extra day or two and then hope the whole routing is available (this doesn't seem common)

So I am open to other options for the way out. As far as I can tell AA and Qantas availability is very spotty for First class awards.

Any other creative options?
