Boeing to start fourth 737 MAX final-assembly line in Everett, expanding narrowbody output for future MAX 10
Boeing will begin operating a fourth 737 MAX final-assembly line at its Everett, Washington complex on Monday, marking the first time the MAX is assembled outside Renton. The move supports accelerated 737 MAX build-out and prepares capacity for the forthcoming 737-10, which remains pending FAA certification for deliveries.
