Each Wednesday, between 11:00am-1:00pm PST, Alaska Airlines holds a “Fast-Dash Sale”. During this Alaska Airlines flash sale you can get some great deals on flights; if they happen to have a route you are interested in.
For example, today’s flash sale has the following deals:
SEA-FAT – $54
SEA-SMF – $54
BOI-SJC – $54
SJC-LIH – $153
It seems that they usually have at least one flight on sale out of Seattle.
