About SEA
Overview
Seattle-Tacoma International Airport, commonly known as Sea-Tac, lies approximately 22 kilometers south of downtown Seattle in the city of SeaTac, Washington. It serves as the primary international gateway for the Pacific Northwest region of the United States. The airport opened in 1949, built to replace Boeing Field as the area's main commercial airport, and has since grown into one of the busiest in North America.
Terminals & runways
Sea-Tac operates a single main terminal with multiple concourses and two satellite buildings connected by an underground transit system. The North Satellite handles primarily domestic flights, while the South Satellite is dedicated to international arrivals and departures. The airport has three parallel north-south runways and operates 24 hours a day. Ongoing expansion projects continue to modernize concourses and improve international processing.
Airlines
Sea-Tac is a major hub for Alaska Airlines, which is headquartered in the Seattle area, and serves as a significant hub for Delta Air Lines. Numerous international carriers operate here, including British Airways, Lufthansa, Air France, Emirates, Korean Air, and All Nippon Airways, connecting the Pacific Northwest with Europe, Asia, and the Middle East.
