History

Sea-Tac Airport was developed as a direct response to the World War II Pearl Harbor attack in 1941 when military needs limited civilian access to existing airports. The federal Civilian Aviation Authority sought a local government to develop new regional airport. The Port of Seattle accepted the challenge and selected Bow Lake in southwest King County for the new airfield. Runway construction was completed in 1944, civilian operation began in 1946, and a modern terminal building was dedicated on July 9, 1949.

Major Renovations/Highlights

  • Over the next five years, the Port of Seattle will spend $1.9 billion in airport improvements including major projects such as the renovation of the north satellite (NorthSTAR), reconstruction of the center runway, a new expanded International Arrivals Facility (IAF) and a new high-efficient, centralized baggage system.

  • Sea-Tac Airport’s Experience the City of Music program highlights local artists who put the northwest music scene on the map. New in 2015, EMP Museum's Pearl Jam concert poster art exhibit was unveiled, (near Gate A1) and features 85 posters from more than 30 artists. The program features overhead music from all NW musicians, live music performances daily throughout the terminal and security and information announcements by locals such as Macklemore, Quincy Jones and Jerry Cantrell of Alice in Chains.

  • In 2014 Sea-Tac was the first North American Airport to receive certification in reducing carbon emissions by the Airport Council International (ACI) Carbon Accreditation Program. Other award winning environmental programs include pre-conditioned air for airplane heating and cooling, charging stations for electric ground support vehicles on the ramp, recycling more than 1,705 tons of material each year, requiring fuel efficient and alternative fuel taxis and ground transportation vehicles, purchasing ‘green’ energy, plus industry-leading wildlife and stormwater management.
