If you’ve dreamed of seeing how today’s commercial airplanes are assembled, look no further than the Boeing Everett Factory Tour, which takes visitors inside the largest manufacturing facility in the world where the 767 Freighter, KC-46A Pegasus Tanker, 777 and 777X are assembled. Here is where aerospace innovation meets modern engineering, and where aviation history continues to unfold.
A Glimpse into Aviation History and Innovation
Boeing’s Everett factory was originally built in 1967 to manufacture the 747 – the plane which revolutionized air travel. To this day, the iconic “Queen of the Skies” remains one of the most popular commercial jets of all time, having flown more than 5.9 billion passengers around the world.

During the 80-minute guided tour which begins at Boeing Future of Flight, visitors are taken up to the factory balcony for a bird’s-eye view of the 777 and 777X assembly process. You will see the intricate process of aircraft production—from the initial assembly of components to the final touches before delivery.
Tour guides enrich the experience by sharing Boeing’s deep roots in the Puget Sound area, which date back more than a century. They also highlight Boeing’s commitment to sustainability and the use of cutting-edge manufacturing technologies, including automation and robotics, that keep the company at the forefront of aerospace innovation.
The Largest Factory in the World
The Boeing Everett Factory holds the Guinness World Record for the world’s largest building by volume. With a floor area of 399,480 square meters, or 98.3 acres, the site covers a whopping 1,025 acres. Here are a few other fun facts:
