Boeing's new 737 assembly line starts moving in Everett By Reuters

Boeing plans to begin operating a fourth 737 MAX assembly line at its Everett, Washington, factory on Monday, adding capacity to meet strong global demand. The new production line, known internally as the North Line, copies the three existing 737 final assembly lines in Boeing’s Renton plant. Boeing CEO Kelly Ortberg said in June that the first aircraft would be “loaded” onto the Everett line on July 6. The company is increasing 737 output from 42 to 47 jets per month after consulting with the Federal Aviation Administration. Boeing does not expect the North Line to raise rates before early 2027, when it aims for 52 aircraft per month, with studies considering up to 70. The ramp-up follows FAA production limits after a January 2024 Alaska Airlines door-plug blowout, and Boeing faces competition from Airbus’ A320neo family.
