Boeing Boost: New 737 MAX Line to Expand Production
Jul 7, 2026 15:38

American aircraft manufacturer Boeing is set to officially launch operations of its fourth 737 MAX assembly line at its Everett, Washington facility on Monday as the company moves to expand production capacity in response to record global demand for commercial passenger aircraft.

Known internally as the "North Line," the new production facility is a key component of Boeing’s long-term strategy to significantly increase the output of its single-aisle passenger jets.

Last June, Boeing President and Chief Executive Officer Kelly Ortberg announced that the company would begin loading the first aircraft structure onto the Everett line on July 6. He described the new facility as a near-identical replica of the three existing 737 assembly lines at Boeing’s Renton plant, located south of Seattle.

In consultation with the U.S. Federal Aviation Administration (FAA), Boeing is currently working toward increasing monthly production of the 737 from 42 to 47 aircraft. However, the new North Line is not expected to make a direct contribution to overall production growth before early 2027.

The company aims to raise 737 production to 52 aircraft per month by early 2027 and is also evaluating the possibility of eventually increasing output to as many as 70 aircraft per month.

Expanding production has become a critical priority for Boeing as it seeks to recover from years of financial setbacks caused by manufacturing disruptions, safety concerns, and supply chain challenges involving key component suppliers.

In January 2024, the FAA imposed strict production limits on Boeing’s 737 program after a door plug detached mid-flight from a nearly new Alaska Airlines 737 MAX 9 aircraft. Following the incident, regulatory oversight of Boeing’s manufacturing operations intensified, and the company temporarily slowed production to address quality control deficiencies.

By volume, Boeing’s Everett facility is the largest manufacturing building in the world. The plant once produced the company's iconic 747, 767, 777, and 787 aircraft. However, after production of the legendary 747 ended permanently and the 787 assembly line was relocated to South Carolina, significant factory space became available, which is now being repurposed for 737 MAX production.

In the commercial aviation market, Boeing’s 737 MAX competes directly with the European aircraft manufacturer Airbus and its A320neo family. Global demand for aircraft in this category remains exceptionally strong, with airlines facing waiting periods of several years for new deliveries.
