Airport Information

Seattle Tacoma International Airport (Sea-Tac)

Seattle–Tacoma International Airport also referred to as Sea–Tac Airport or Sea–Tac is the primary commercial airport serving the Seattle metropolitan area in the U.S. state of Washington. It is in the city of SeaTac, approximately 14 miles (23 km) south of Downtown Seattle and 18 miles (29 km) north-northeast of Downtown Tacoma. The airport, the largest in the Pacific Northwest region of North America, is between Portland, Oregon, and Vancouver, British Columbia, and owned by the Port of Seattle.

The airport was built by the Port of Seattle in 1944 after the U.S. military took control of Boeing Field in World War II. The first scheduled airline flights were Northwest and Trans-Canada in 1947; Western and United moved from Boeing Field in the next couple of years, and Pan Am moved in 1952–53, but West Coast and successors Air West and Hughes Airwest stayed at Boeing Field until 1971. The original terminal was designed by architect Herman A. Moldenhour. The official opening ceremony took place on July 9, 1947 in front of a crowd of 30,000.

Today the airport has flights to cities throughout North America, Europe, the Middle East, and Asia. It is the primary hub for Alaska Airlines, whose headquarters are near the airport. It is also a hub and international gateway to Asia for Delta Air Lines, which has expanded at the airport since 2011. Thirty-four airlines serve 91 non-stop domestic and 28 international destinations.
