The airport plays a central economic role that reverberates throughout the south sound and across the Pacific Northwest. Since opening in 1947, Sea-Tac has become one of the largest airports in the nation, a major contributor to the regional economy and a leader in environmental stewardship.
By providing national and international connections for business and personal travel, as well as cargo shipping, its regional economic impact is more than $16.3 billion in business revenue. With 22 scheduled passenger airlines serving 77 non-stop domestic destinations and 22 international cities, the airport generates more than 171,750 jobs, of which almost 110,000 are direct jobs, representing more than $2.8 billion in direct earnings and $565 million in state and local taxes.
Over the next five years, the Port of Seattle will spend $1.9 billion in airport improvements including a renovation of the north satellite, reconstruction of the center runway, a new expanded International Arrivals Facility and a new high-efficient, centralized baggage system.
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 wildlife and stormwater management.
