About flying from SEA

Seattle-Tacoma International Airport is the primary hub for Alaska Airlines and one of the most important airports in the western United States. Alaska's extensive network from Seattle covers domestic destinations across the US, Canada, and Mexico, alongside strong transcontinental routes to the East Coast.

Delta Air Lines has invested heavily in Seattle as a second hub, competing directly with Alaska on many key routes. This Alaska-Delta competition at SEA often benefits travelers with strong fare competition on domestic routes.

Seattle's growing tech economy, home to Amazon, Microsoft, and Boeing, drives significant business travel demand and supports high frequencies on routes to San Francisco, Los Angeles, New York, and other corporate travel markets.
