I currently have enough AA miles to do 1st class one way to Japan and Japan to Australia. I have enough Chase UR to do the Virgin Atlantic sweet spot to Japan. I have more then enough MR points. I would preferably like to burn my airline AA miles 1st. I would love a Qantas 1st class flight from DFW to SYD, but have not seen any award availability for that flight. Matter of fact I did see one weird routing a few months back. it was LAX-DFW-SYD. Then if I searched the same date DFW-SYD the 1st class flight wouldn't show up. Still those date were just a dummy search.
