Visitors view the assembly of a Boeing 777 inside the Everett factory. Since 1968, more than 6 million people have taken the Boeing Everett Factory Tour.

If you’ve dreamed of seeing how today’s commercial airplanes are assembled, look no further than the Boeing Everett Factory Tour. The 80-minute guided tour takes visitors inside the largest manufacturing facility in the world where you can witness assembly of the 777 aircraft family, including the highly anticipated 777X—the world’s largest twin-engine widebody jet—inside the biggest manufacturing building on the planet.

From the factory balcony, see where aerospace innovation meets modern engineering, and where aviation history continues to unfold inside the storied Everett plant.

Legacy and innovation under one roof

Originally built in 1967 to assemble the revolutionary Boeing 747—the iconic “Queen of the Skies” that transformed global air travel—the Everett factory continues to push the boundaries of aviation. Today, it is home to the assembly of the 767 Freighter, KC-46A Pegasus Tanker, and the 777 and 777X.

Guided tours begin at Boeing Future of Flight in Mukilteo, before a private tour bus brings visitors into the Everett site. Once inside and standing on the factory balcony, you’ll witness the U-shaped assembly line that brings these engineering marvels to life.

The Boeing Everett Factory is not just a manufacturing site; it’s a symbol of the Puget Sound region’s deep-rooted passion for innovation. Covering an astounding 399,480 square meters (98.3 acres) under one roof, it holds the Guinness World Record for the largest building by volume. To put it in perspective, the factory’s floor area could comfortably fit Disneyland Park, the Vatican City, the Pentagon, the U.S. Capitol, and the Taj Mahal—all under one roof.

Seventy-five American football fields could fit inside this colossal space, where generations of dedicated employees—affectionately known as “The Incredibles”—have built aircraft that connect the world. Their story began alongside the construction of the factory itself, assembling the first 747-100 while the building was still rising around them.

Inspiring tomorrow’s workforce

The Boeing Future of Flight center complements the factory tour with interactive exhibits and immersive programs that celebrate Boeing’s century-long legacy in aerospace. It’s a place where visitors of all ages can connect with the passion that drives innovation, from the earliest days of flight to today’s cutting-edge technologies.

Among the newest exhibits is the Boeing Aerospace Adventure where visitors take a hands-on approach to learning about STEM skills and the innovative thinking behind

aircraft design, maintenance, and commercial aerospace solutions that are shaping the future of flight.

The exhibit is perfect for middle school and high school students to explore the science of flight and envision their interests in engineering, as well as technical and non-technical professions related to a career in aerospace. The experience concludes with flight simulators which use satellite imagery of the Pacific Northwest and detailed renderings of the 787 Dreamliner and F/A-18 Super Hornet to create a realistic flying experience.

Plan your visit: Boeing Future of Flight is located in Mukilteo, 29 miles north of Kirkland, and is open daily.
Today, the Boeing Everett Factory Tour remains one of the most popular public attractions in the region offering a rare, behind-the-scenes look at how some of the most advanced commercial airplanes come to life before delivery to airline customers worldwide.
