About The Airport

Ranked the #1 Best Airport in North America 2022 by Skytrax

SEA totaled over 50 million passengers in 2023-down just over 2% from 2019 - with a forecast to reach pre-pandemic traveler volumes in 2022. Seattle-Tacoma International Airport (SEA) is the largest airport in the Pacific Northwest and the 8th largest in North America. SEA serves as a hub for both Alaska Airlines and Delta Air Lines. Seattle's location as the closest West Coast city to both Europe and Asia makes it an ideal international gateway, a fact that has made Seattle one of the fastest-growing airports in North America for the past five years.

SEA earned the travel industry's prestigious 4-Star Skytrax Airport Rating, focused in customer-centered travel with better services, facilities, and amenities. 

As the headquarters of major multinational corporations such as Boeing, Microsoft, Amazon, Starbucks, and the Gates Foundation, Seattle boasts a strong economic climate and the most well-educated population of any major city in the United States. Seattle also serves as the gateway for Washington State's well-known, high-value agricultural commodities such as seafood and cherries. Washington State is the largest exporter per capita in the United States, and a full one-third of all jobs in the state are related to international trade.
