San Francisco → Seattle

About this corridor

The northbound return of the Bay Area–Seattle lane. San Francisco to Seattle empty legs appear steadily as jets shuttle between the two tech hubs.

Because San Francisco and Seattle sit on such a well-travelled lane, operators regularly need to reposition aircraft in both directions — and a repositioning flight with empty seats is exactly what becomes an empty leg. The result is a steady stream of discounted one-way flights for travellers whose dates are flexible.
