Boeing to open fourth Everett 737 MAX line, aims for ~63 jets/month

Boeing will open a fourth 737 MAX 'North Line' at its Everett, Washington complex mid-2026 to begin MAX 8/9 assembly and eventually produce the larger MAX 10. The new line underpins Boeing's plan to lift 737 output to about 63 aircraft per month to meet rising airline demand.

Briefing

What Hype is tracking

The move materially increases narrowbody production capacity to roughly 63 737s/month, accelerating deliveries against Boeing's multi‑thousand‑aircraft backlog and supporting airline fleet plans (see MAX 10 development context) (source:cf2e49ec-2d06-4611-a7f7-33c6d034565e).
Activating Everett's North Line is the operational step that complements Renton rate rises and previous production increases, altering supplier loadings, staffing needs and logistics across the 737 supply chain (source:8523853c-ff88-424a-9b48-89885f47efef) (source:ed7118e7-a563-40d4-b512-48553d9d1773).
The North Line is scheduled to transition to MAX 10 work once regulatory approvals and flight‑test milestones are met, linking this capacity expansion directly to the MAX 10 certification timeline and delivery pacing (source:08de2c3e-d68f-469b-8b19-5056911f45bc).
