Via The Flight Deal, even more discounted trips to Australia! This time, flights originate in Seattle, Atlanta, Detroit, Minneapolis, or Salt Lake City, and the carrier is United instead of Delta. Use Google Flights to search for dates. Here is a sample trip from SEA-MEL for $568.
Check Where to Credit to find the best place to credit your miles. Again, you probably won’t want to credit them to United.
Dates: Valid until November 30, 2016.
Requirements: Purchase at least 14 days in advance, 10 day minimum stay.
Stopovers: N/A (allowed, but doesn’t actually seem possible)
