Boeing’s decision to stand up a fourth 737 Max assembly line in Everett, Washington, marks a pivotal shift in how the company plans to build its most important jet. The new line, slated to open by midsummer, is central to a push to lift output of the 737 family from roughly 42 aircraft a month toward a target of 63, a level that would represent a record pace for the program. The move signals both confidence in resurgent demand and a high‑stakes bet that Boeing can scale safely after years of scrutiny and disruption.
At its core, the expansion is about more than just adding capacity. It reactivates a storied widebody factory with a new narrowbody mission, redistributes work away from the saturated Renton site, and tests whether Boeing’s industrial system and suppliers can keep up with airlines’ appetite for single‑aisle jets. The question now is whether this surge in production will cement Boeing’s recovery or expose fresh vulnerabilities in its supply chain, workforce, and regulatory relationships.
Everett’s new line and the race to 63 a month
Boeing is preparing to open a dedicated 737 Max line in Everett that will operate alongside three existing lines in Renton, effectively turning the Puget Sound region into a dual‑hub narrowbody campus. Company leaders have outlined a plan to lift monthly output of the 737 family from about 42 jets to a target of 63 737 jets a month as the Everett line ramps. That ambition underscores how central the single‑aisle workhorse remains to Boeing’s financial health and to airlines that have built their growth plans around the Max family.
The Everett facility, long associated with widebodies, is being reconfigured to host this new narrowbody flow, with the company already training staff and staging tooling for the midsummer start. Reporting from Lynnwood indicates that Boeing plans to open the fourth 737 M production line in mid‑summer in Everett, Washington, with staff already in training for the new operation. Separate coverage from Lynnwood notes that the company’s broader plan is to move from the current 42 jets a month toward higher rates as demand and regulatory approvals allow, a trajectory echoed in plans to open the fourth line in midsummer.
Why Everett, and why now?
Choosing Everett for the new line is as much a strategic signal as an operational decision. The site, historically home to widebody programs, has spare floor space after production shifts and program sunsets, and it sits in a community with deep aerospace skills. Local reporting describes how Boeing will open AX line in Everett by midsummer, reusing parts of The Boeing Evere campus that had been underused. That choice keeps thousands of jobs and supplier relationships anchored in Snohomish County rather than dispersing work to lower‑cost regions.
The timing also reflects a narrow window in the market cycle. Airlines are pressing for deliveries to meet post‑pandemic travel demand, while Airbus’s A321neo family continues to rack up orders. Boeing executives have outlined at a conference north of Seattle how they are mapping plans to hike 737 Jet Production to a Record Rate, with the Everett line a central lever. In that context, the new line is less a luxury than a defensive move to avoid ceding more single‑aisle market share.
Max 10 focus and the Airbus A321neo contest
The Everett line is expected to lean heavily toward the largest variant, the 737 Max 10, which is Boeing’s closest answer to the Airbus A321neo in terms of range and seat count. Earlier planning documents describe how Boeing is planning to build a fourth 737 production line at its Everett, Washington facility dedicated to the Max 10. Concentrating that variant in Everett should simplify tooling, training, and certification flows, while freeing Renton to focus on other Max models and retrofit work.
This specialization matters because the Max 10 is central to Boeing’s pitch to low‑cost carriers and network airlines that want high‑density, single‑aisle aircraft for transcontinental and medium‑haul routes. Social‑media chatter has already highlighted that Boeing is preparing to assemble 737 M AX jets in Everett, Washington, marking the first time the narrowbody will be built outside Renton. If Everett can reliably turn out Max 10s at scale, I expect quarterly delivery splits between Boeing and Airbus in the largest single‑aisle segment to tighten over the next 18 months, particularly as airlines seek fleet commonality and quick delivery slots.
Jobs, Snohomish County and the local squeeze
For Snohomish County, the new line is both an economic boost and a stress test for local infrastructure. Video coverage from the region shows that Boeing has started hiring for 737 production on the new North Line based out of its Everert facility, drawing workers from across the County. That hiring wave will ripple through housing, schools, and transport, particularly as Everett absorbs workers who might otherwise have been based in Renton or out of state.
Local business groups are already positioning to capture spillover spending from the expansion, from machine shops around Paine Field to service businesses that cater to shift workers. At the same time, community leaders are watching whether the influx of higher‑paid aerospace jobs will intensify pressure on an already tight housing market. A separate report on Boeing’s recent financial performance notes that year‑over‑year sales soared nearly 60%, with revenue rising to over $23 billion from $15.24 billion, which gives the company more room to invest in workforce development and local partnerships if it chooses to do so.
Suppliers, Spirit and the fragile production web
Scaling to 63 aircraft a month is not just a question of floor space in Everett; it depends on a sprawling network of suppliers that have to match Boeing’s tempo. The most visible of these is Spirit AeroSystems, which builds 737 fuselages and has struggled with quality and labor issues in recent years. Industry briefings from Lynnwood and other hubs describe how Boeing plans to open the fourth line while gradually stepping up from 42 jets a month, a cadence that will require suppliers to add shifts, tooling, or both.
In practice, that means the Everett ramp will likely proceed in phases, with Boeing holding back from the full 63‑jet target until it is confident that upstream parts and systems can arrive on time and at quality. Analysts who track the program have noted that the company is already training staff for the new line and staging work in Everett, as reflected in coverage that Companies like Boeing are already preparing staff for the Everett MAX line. My read is that any supplier stumble will show up first as “traveled work” into Everett, which would slow the ramp and risk repeating past quality lapses.
