I have a lot of Alaska Miles and since they are selling them on a 50%+ basis, figured use 'em or watch them depreciate.

I saw Singapore is starting non-stop service out of SEA so I did a mock search w/completely random dates but after 9/3/19--and then used the monthly calendar. No luck.
Then I turned my attention to London. Hong Kong. Tokyo. Auckland. Paris. I found no availability for 2 people anywhere a full year out. I found lots of what shows up as F class but it's F class to SFO/LAX/ORD/DFW and then connecting transatlantic or transpacific in coach.

Am I doing something wrong?
