About The Airport

With over 49.8 million passengers in 2018, 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.

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 third of all jobs in the state are related to international trade.
