Route Overview
58% off Boise to Seattle flights. If you fly Boise (BOI) to Seattle (SEA) even twice a year, you are leaving money on the table at $202 standard fares. This 398-mile sector flies in about 1h 20m and is one of our best-performing domestic routes, where we consistently see $84 one-way deals — savings of 58% versus booking directly.
Seattle is the Pacific Northwest hub with Alaska Airlines' home base. Whatever pulls you there — business, family, getaway — the fare strategy is the same: don't book the first price you see. Boise is a high-traffic market, which means strong competition on the BOI–SEA sector and real room for agent deals.
