Being built to meet record breaking demand for international traffic, according to the airport the multi-level 450,000 square foot facility will "significantly enhance the international passenger experience" and advance the Puget Sound region as a leading tourism and business gateway.
The project is scheduled to break ground in early 2017 and open in late 2019.
“Our international travel continues to grow at a double-digit pace, but what welcomes international travellers to Sea-Tac is a cramped, 1970s facility that is well beyond its planned peak capacity," admits Port of Seattle Commission president, John Creighton.
"The IAF project is a critical investment for the region’s economy that will create a proper welcome mat for both business and leisure travellers.
“The new facility will help drive the port’s Century Agenda strategy to double the number of international flights and destinations over 25 years.”
The IAF will be a new, multi-level, 450,000 square-foot facility located east of the current Concourse A.
An iconic aerial walkway will span 900 linear feet across and 85 feet over the existing taxi lane to connect arriving international passengers from the south satellite across the top of concourse A to the new IAF.
In addition, a secure international corridor will be built on concourse A to nearly double the number of existing international gates from 12 to 20.
The new International Arrivals Facility will increase peak passenger capacity by more than double to 2,600 passengers per hour.
Currently Sea-Tac sees daily peak passenger levels averaging over 2,000 passengers per hour for a facility designed for only 1,200 per hour.
Additional benefits of the new facility will include 50 new passport check kiosks; three new baggage carousels; direct access from the IAF to ground transportation at airport drives or garage; and a reduce minimum passenger connection time – down from 90 to 75 minutes.
The current budget for the IAF is $660 million.
Funding for the project will come from a combination of airport generated revenues, passengers facility charges (PFC’s), and revenue bonds. As with virtually all airport projects, no Port of Seattle taxes will be used.
