CURRENTLY CLOSED! The Future of Flight Aviation Center & Boeing Tour is one of Seattle's most-loved, premier attractions. Located just 25 miles north of Seattle, the Boeing Tour is a one-of-a-kind opportunity to view 747, 777, and 787 Dreamliners being assembled on the Everett production line before they take to the sky. Each tour is approximately 90 minutes long and includes fascinating facts about Boeing and the planes that bear its name.
