International Arrivals Facility​

The Port of Seattle is working on conceptual design of an expanded International Arrivals Facility (IAF) at Seattle-Tacoma International Airport. With a dramatic increase of international flights, the existing U.S. Customs area (or Federal Inspections Services) is an aging facility - opened in 1973 - that will exceed capacity within the next five years. The IAF will create upgrades and expansion to advance the Puget Sound region as a leading tourist and business gateway and provide a much improved passenger experience. This new facility will focus resources to advance the port’s Century Agenda strategy to double the number of international flights and destinations over the next 25 years.

International Traffic Facts
  • International passenger activity requiring U.S. Customs clearance at Sea-Tac has grown 59% since 2004.
  • Twelve new international routes have been added since 2007 (including Paris, Frankfurt, Beijing, Reykjavik, Osaka, Shanghai, Tokyo-Narita, and Dubai).
  • A consultant study estimates each new international route generates $75 million annually in direct and indirect economic impact to the region.
Peak Problem
  • Congestion becomes a critical problem at Sea-Tac during the mid-day peak period due to aircraft schedules. The mid-day peak has increased by 116% since 2004.  
  • On a typical day, 1,200 international passengers now arrive in a single hour, creating capacity problems in the current facility which can lead to airlines holding passengers onboard aircraft due to a lack of space for aircraft at the gates or for passengers in the customs facilities.
IAF Estimated costs
  • The current options under discussion call for building a new IAF with early budget estimates of $344 million. Updated budget estimates are set to be reviewed by the Port of Seattle Commission in late 2014.
