The Port of Seattle is building a new, expanded International Arrivals Facility (IAF) at Sea-Tac Airport to meet growing regional demand for international service, enhance the passenger experience, advance the Puget Sound region as a leading tourism and business gateway and serve the traveling public well into the future. The current 1970’s vintage facility in the South Satellite is servicing a dramatic increase in flights and the existing Federal Inspections area (commonly known as customs) is beyond its peak capacity. The new facility will also help achieve the Port’s Century Agenda goal to increase the number of international flights and destinations over the next 25 years.


Benefits of New International Arrivals Facility

IAF Benefits 

  • ​Increase passenger capacity by more than double to 2,600 passengers per hour
    More than double passport check positions and kiosks (from 30 to 80 kiosks)
  • Increase size and number of bag claim carousels from four to seven
  • Reduce minimum passenger connection time from 90 to 75 minutes
  • The IAF will be a new multi-level, 450,000 square-foot facility located east of the current Concourse A
  • An iconic aerial walkway, which will span 900 feet across and 85 feet above the existing taxi lane,  will connect arriving international passengers from the South Satellite across the top of Concourse A to the new IAF​


  • The current budget for the IAF is $766 million. Funding for the project will come from a combination of airport generated revenues, passenger facility charges (PFC’s) and revenue bonds. As with virtually all airport projects, no tax-payer dollars will be used to fund the project



Additional details about the new facility

  • Contractors link to general contractorThe iconic aerial walkway will be prefabricated at the north end of the airport, then transported to the south end overnight for installation in order to reduce impacts to taxiway use.
  • A new security corridor along the face of the existing Concourse A will allow eight international wide-body aircraft gates to access directly into the IAF. These gates will also allow dual use for domestic flights into Concourse A.
  • As part of the Port of Seattle’s emphasis on environmental stewardship and sustainability, the project is designed to achieve LEED V4 (Leadership in Energy and Environmental Design, Version 4) Silver certification from the United States Green Building Council.
  • The baggage claim devices will nearly triple in size, from four devices with 668 lineal feet in the current space to seven devices and 1,806 linear feet!
