I should be able to return before KE's blackout start date of 7 FEB 2013.
The 331-day calendar has not rolled around yet so that I can book the return yet.

Here's the question: Amazingly, I can find biz class availability on DL for the outbound LAX-SYD after Christmas! Should I spend two x 150,000 miles (low) now to grab that -- while hoping to add return later (on anybody if I have to)? I'm Diamond, I think changes are free.
