The most complex building project in SEA’s 70+ year history, the new facility expands capacity and speeds up the international arrivals process. The IAF comprises an aerial walkway—the longest of its kind in the world—a Grand Hall, and a secure corridor to increase the number of international-capable gates. The IAF is a new multi-level, 450,000-square-foot facility located east of the current A Concourse. An iconic aerial walkway, which spans 780 feet across and 85 feet above the existing taxilane, connects arriving international passengers from the S Concourse across the top of the A Concourse to the new IAF.

The IAF includes exciting new elements:

• 450,000-square-foot grand hall for baggage claim and customs processing
• 85-foot-high aerial walkway that directly connects passengers from the S Concourse (formerly South Satellite) to the Grand Hall
• New international corridor connecting arriving international passengers on A Concourse
