SEATTLE—Seattle-Tacoma International Airport continues to boast significant growth in the number of international airlines. In 2018, three new airlines began service, with three more scheduled for 2019. And, during the last decade, the number of passengers requiring US Customs clearance at Sea-Tac doubled. Passenger volume during peak periods climbs well above the levels the current facility was meant to hold. As a result, passengers often must wait in airplanes at the gate or in current hallways before going through customs or picking up luggage.
In order to increase capacity levels and provide a major upgrade for international passengers, a new International Arrivals Facility/IAF is underway at Sea-Tac. The project is rapidly progressing towards its scheduled opening in the fall of 2020 when the new 450,000-square-foot grand hall will be five times larger than the current 1970s-era facility. The IAF, the most complex capital development program in the history of the 69-year-old airport, will significantly improve the arrival process for international passengers without adding new gates.
