Boeing delivered 33 jets in September, down from 40 in August, as production was impacted by a strike involving around 33,000 U.S. West Coast factory workers that began mid-month.
The September deliveries, while up by six compared to the same period in 2023, reflect the challenges Boeing has faced, particularly with its 737 MAX production.
Last year, the company struggled with a manufacturing defect, further reducing output.
The strike, which began on September 13, halted production of the 737 MAX, along with Boeing's 777 and 767 widebody jets.
These models are key revenue drivers for the company, which is already grappling with reduced narrowbody production due to ongoing quality issues and weak margins in its defense segment.
Boeing delivered 27 MAX jets in September, with five going to United Airlines, and three each delivered to Ryanair and Southwest Airlines.
The CEOs of these airlines have voiced concerns over reduced deliveries.
Delivery numbers are closely monitored by investors since most of the payment for a jet is received upon delivery. Boeing has indicated that future deliveries will likely be lower due to the ongoing strike.
In terms of new orders, Boeing booked 65 gross orders in September, including 54 737 MAX jets and 11 777 freighters for undisclosed customers. On September 19, China Development Bank Financial Leasing announced an order for 50 737 MAX jets.
Year-to-date, Boeing has recorded 315 gross orders through September 30, with a net total of 272 orders after cancellations and conversions. Following further accounting adjustments, the company reported 121 adjusted net orders so far this year. Boeing has delivered 291 airplanes in total during 2024, including 225 737 MAX jets.
