Looks like United is have an announced sale with 20% off Saver Awards within the United States, including Hawaii and Alaska. The discount is only applied to round-trip flights.

• Domestic short-haul saver round-trips will be 16K instead of 20K miles
• Domestic saver round-trips will be 20K instead of 25K miles
• Alaska saver round-trips will be 28K instead of 35K miles
• Hawaii saver round-trips will be 36K instead of 45K miles

Good opportunity if you were planning a trip but there’s not a lot of availability during peak season. There’s also blackout dates on November 22, 23, 26, 27 and 28.
