Boeing (BA) plans to bring a fourth assembly line for the 737 Max online in Everett, Washington, by mid-summer, Reuters reported Tuesday.
The new line, known internally as the North Line, is part of Boeing’s (BA) broader effort to lift monthly production of the best-selling 737 Max. The company is currently moving from a rate of 38 aircraft a month toward 42.
Speaking at the Pacific Northwest Aerospace Association’s Advance 2026 conference, Katie Ringgold said suppliers should prepare for additional increases in the coming months. She told attendees that Boeing expects output to rise by roughly 15% over the next 18 months, Reuters reported.
That trajectory is consistent with Boeing’s (BA) next production target of 47 737 Max jets per month, a level the company has previously identified as a key milestone in its recovery plan.
