The Hub of the Northwest

Sea–Tac Airport is the largest hub for Alaska Airlines and Horizon Air. Together, they account for nearly half of the airport's daily flights. However, a total of more than two-dozen airlines serve the growing airport.

Together they provide direct service to most major U.S. cities, and destinations in Canada, Mexico, Asia, and Europe.

Southwest, United, and Delta (including Northwest Airlines) all have a major presence at Sea-Tac. Sea-Tac also has significant air cargo traffic.

Sea–Tac Airport has three parallel runways that run in a largely north-south direction, with a passenger terminal on the eastern side. The runways range in length from about 8,500 to 12,000 feet.

In the past 15 years, the airport added a third terminal, a third runway, and an air traffic control tower. The airport continues to modernize and expand to meet aviation and customer needs.
