International Arrivals Facility

Shorter waits at customs and baggage claim. More gates for international passengers. And, a world-class experience.

With the Puget Sound region now serving as a leading tourism and business gateway to the world, SEA’s new International Arrivals Facility will meet the demand for international travel while using sustainable development practices.

Spend less time waiting to explore the world

SEA is the closest U.S. West Coast gateway to both Europe and Asia, and has been named the 10th most connected international hub in the U.S, according to the 2019 OAG Megahubs Index. In the past decade, international passenger activity in the customs facility at SEA has more than doubled, growing 107 percent from 2007 to 2017. Travelers at SEA benefit from more choice and lower cost as international service expanded to more than 650 one-stop connections.

When we open the new International Arrivals Facility, travelers will spend less time waiting at customs lines and baggage claim, allowing for faster connections between flights.

Soon travelers will experience our sustainable features including energy-efficient LED lighting and a centralized system for heating and cooling.

Delivering on international travel

The moment a traveler steps onto the iconic aerial walkway to the new sustainably-built International Arrivals Facility, they’ll appreciate the difference from the 1970s era facility serving them today, which will include:

  • A 450,000-square-foot grand hall for baggage claim and customs processing
  • An 85-foot high aerial walkway connecting passengers from the South Satellite to the grand hall
  • A new sterile corridor allowing eight existing domestic gates on Concourse A to also serve international passengers during peak periods, bringing the airport’s total of international-capable gates from 12 to 20
  • More than double the number of existing passport check positions, kiosks, and baggage claim services

Improving your customs experience

The Federal Inspections area (known as customs) today operates beyond the capacity for which it was originally designed. Since 2017, SEA has welcomed 12 new international services, including routes to seven previously-unserved international destinations: Dublin, Hong Kong, Mexico City, Munich, Osaka, and Singapore.

The guaranteed maximum price of the International Arrivals Facility program of projects is set at $968 million. Funding for the project will come from a combination of airport-generated revenues, passenger facility charges, and revenue bonds. As with virtually all airport projects, no taxpayer dollars will be used to fund the project.
