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-Tac Airport’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-Tac is the closest U.S. West Coast gateway to both Europe and Asia. In the past decade, international passenger activity in the customs facility at Sea-Tac has more than doubled, growing 107 percent from 2007 to 2017.

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 includes:

  • A 450,000 square foot grand hall for baggage claim and customs processing
  • An 85-foot high aerial walkway that will directly connect passengers from the South Satellite to the grand hall
  • A new sterile corridor that will allow 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. Over the past 10 years, Sea-Tac has welcomed 16 new intercontinental services, including routes to Beijing, Dubai, Frankfurt, Hong Kong, Reykjavik, Shanghai, and Shenzhen.
