Boeing’s 737 production-rate plan for 2026 (how they intend to ramp)

Based on Boeing’s 2026 Q1 earnings transcript, the company’s plan for increasing the 737 production rate in 2026 is structured as a sequence of rate steps, enabled first by stabilizing the current Renton line and then by bringing a second 737 production line (the “North Line”) online in Everett, with FAA authorization and safety/quality processes governing the final ramp.

1) Maintain stability at 42 airplanes/month (already achieved)

Boeing stated the 737 program “stabilized at a rate of 42 per month” and that the 42/month plan was executed. ¹²³
Boeing also described progress reducing rework hours and being “on track” for delivery targets while holding this stabilized rate. ¹²

2) Increase to 47 airplanes/month in Renton “this summer”

Boeing’s plan is a production increase from 42 to 47 per month “this summer.” ¹²³
Management also emphasized that the company expects to benefit from “buffer inventory during the transition” to that 47/month level. ¹

3) Ramp beyond 47 to 52 airplanes/month by activating the 737 North Line (Everett)

Boeing explicitly linked the next step (47 → 52) to operationalizing a new 737 production line outside Renton:

Boeing said that “production rate increases above 47 per month will be enabled by activating the 737 North Line in Everett.” ¹
The North Line is “expected to begin operations later this year at a low rate of initial production” to demonstrate conformity to the FAA “that will allow operations under [Boeing’s] current production certificate.” ¹
After completing the initial units, Boeing said it would follow a “safety and quality plan” and “increase rate to 52 per month when the entire production system is ready.” ¹
Management described that the ramp to 52 will involve workforce integration—bringing people “through the Renton production system” to build experience in a stable environment, moving experienced folks from Renton to Everett, stabilizing, and obtaining FAA authorization for that line. ³

4) What Boeing says is different about the 47 → 52 step (timing and constraints)

Boeing characterized 42 → 47 as a “similar” rate increase to earlier steps (conceptually), while noting that 47 → 52 has “a couple of important dynamics” because it depends on bringing in the Everett North Line and the associated stabilization + FAA authorization. ³
Boeing also indicated the 47 → 52 ramp timing depends on executing those operational and regulatory prerequisites while producing at 47 during the transition and then moving to burn down inventory at 52, which also changes supply-chain dynamics (less reliance on inventory levels than at earlier steps). ³

Bottom line

For 2026, Boeing’s 737 production-rate increase plan is:

Hold/operate at 42/month initially. ¹²³
Ramp to 47/month in Renton “this summer.” ¹²³
Ramp to 52/month by activating the Everett 737 North Line, starting later in the year at a low initial rate, obtaining FAA conformity to allow operations, then using Boeing’s safety/quality plan to scale the full system to 52/month once ready. ¹³
