I received an email from Alaska that flights to the following destinations are heavily discounted for award travel that is purchased by April 11 and done by July 31st
Dublin
Hanoi
Reykavik
Calgary
Sydney, Australia
Tashkent
I looked up Dublin out of curiosity and you can go nonstop Seattle to Dublin on AerLingus for 17,500 miles. This is a great deal if it fits your schedule.
