The airlines are now making up for lost revenue during Southwest's long running $198 RT or less coast to coast fares. These fares didn't even require a Saturday night stay. Out of curiosity, I tried GEG-MHT (which is a Southwest city) and got the same high fare. Identical fares for GEG-BOS,NYC,MHT, or ALB.
My advice: Fly to ALB via LON.

Cheaper, and think of the miles!
