Boeing handed over 60 commercial jets in May 2026, a 33 percent jump from the same month a year earlier, but the company still fell short of rival Airbus, which delivered 81 aircraft after clearing a backlog tied to Chinese customers. The May count included 51 of Boeing’s workhorse 737 MAX narrowbodies, a figure that reflects progress on a wiring defect that had threatened to slow the production line earlier this year. For airlines waiting on new planes and investors tracking the duopoly’s recovery race, the 21-jet gap between the two manufacturers captures both how far Boeing has climbed and how much ground it still needs to cover.
Why the 60-jet May tally changes Boeing’s trajectory
The delivery number matters because it is the clearest monthly signal of Boeing’s ability to convert assembled aircraft into revenue. Each jet that leaves the factory and enters airline service triggers a final payment, and Boeing’s cash flow has been under pressure since a series of quality setbacks slowed 737 MAX production starting in early 2024. Hitting 60 in a single month, with 51 newly delivered 737 MAX jets, suggests the company is working through a bottleneck that had kept finished planes parked at its facilities.
That bottleneck traces back to a machining error discovered earlier this year. The error scratched wiring bundles inside certain 737 MAX fuselages during assembly, forcing Boeing to inspect and repair affected aircraft before they could be handed to customers. Boeing acknowledged in March that the flaws would slow some deliveries, though the company also said that aircraft already in airline service could continue to operate safely. The May delivery figure indicates that remediation work on at least a portion of those planes has been completed, freeing them for handover.
The 60-jet result also helps reset expectations after a choppy start to the year. Earlier months had seen lower output as Boeing paused some work to address the wiring issue and respond to heightened regulatory scrutiny. May’s performance, while still trailing Airbus, shows that the manufacturer can lift deliveries even while repairs are under way. For Boeing’s leadership, that is critical to convincing customers and investors that the worst operational disruptions are moving into the rear-view mirror.
A central question for the summer months is whether resolving the wiring issue can shorten the gap between final assembly and delivery enough to let Boeing outpace Airbus on a monthly basis. If the fix trims the average hold time by two weeks or more on affected 737 MAX aircraft, Boeing’s June through August run rate could, in theory, surpass Airbus’s for the first time since 2024. That scenario depends on several variables that neither manufacturer has publicly quantified: the exact number of planes still awaiting wiring repairs, the pace of FAA sign-offs on reworked jets, and whether Boeing’s supply chain can keep feeding the Renton, Washington, assembly line at a steady clip.
For airlines, the timing of that potential inflection point matters more than the headline gap in any single month. Carriers planning summer and autumn schedules need confidence that promised aircraft will arrive on time so they can open new routes or increase capacity on existing ones. A sustained stretch of 60-plus monthly deliveries from Boeing would give schedulers more certainty and ease the pressure to line up short-term leases or extend the life of older jets.
Boeing’s backlog and Airbus’s China rebound in the same frame
Boeing’s order backlog stood at 6,178 jets as of its latest disclosure, a figure that spans the 737 MAX, 787 Dreamliner, and 777F freighter programs. That backlog represents years of future production, but it only translates into cash when planes are built and delivered on schedule. The 60-jet May result, while an improvement, still leaves Boeing producing at a rate that would take decades to clear the queue at current speed. Airlines that placed orders years ago are watching delivery timelines closely, and some have publicly explored leasing older aircraft or shifting capacity to Airbus to fill gaps.
On the Airbus side, the 81-jet May total reflected a specific tailwind: the easing of a logjam involving deliveries to Chinese carriers. Airbus had seen a buildup of finished A320neo-family jets awaiting acceptance by Chinese airlines, a situation tied to trade and regulatory friction. With that China-related bottleneck easing, Airbus was able to push a batch of stored inventory out the door, inflating its May count beyond what its underlying production rate alone would suggest. That distinction matters: if Airbus’s May surge partly reflects a one-time inventory clearance rather than a sustained rate increase, the gap between the two manufacturers may narrow in the months ahead even without a dramatic Boeing acceleration.
The competitive dynamic between Boeing and Airbus plays out not just in monthly tallies but in airline fleet decisions that lock in orders for a decade or more. When Boeing’s delivery pace lags, carriers shopping for new narrowbodies have a concrete reason to lean toward the A320neo family, which Airbus can promise sooner. Every month that Boeing closes the gap reduces that structural disadvantage and makes it easier for sales teams to argue that customers will receive comparable capacity on roughly similar timelines.
Widebody programs add another layer to the comparison. Boeing’s 787 and 777 freighter lines feed demand for long-haul passenger and cargo operations, while Airbus counters with the A350 and A330neo. Both manufacturers rely on these higher-margin jets to support profitability, but narrowbodies like the 737 MAX and A320neo still dominate volume. That is why the wiring issue and its impact on single-aisle deliveries loom so large in assessments of Boeing’s overall health.
Open questions on wiring repairs and summer delivery targets
Several pieces of the puzzle are still missing from the public record. Boeing has not disclosed how many 737 MAX aircraft were affected by the wiring defect or how many remain in the remediation pipeline. Without that number, analysts and airlines cannot model with precision how quickly the delivery backlog will clear. The company’s March statement confirmed the root cause, a machining error that scratched wiring bundles, but offered no timeline for completing all repairs.
Industry analysts are watching for signs of strain in Boeing’s supplier network as the company works through the issue. Wiring harness manufacturers, fuselage suppliers, and avionics providers all have to coordinate rework activities, and any mismatch in capacity could create new bottlenecks even as the original defect is addressed. If repair teams cannot keep pace with the flow of newly built fuselages, partially completed aircraft could again accumulate on the ground.
Boeing has also not updated its full-year 2026 production guidance to reflect the wiring issue or its resolution. That leaves investors relying on fragments of information from monthly delivery reports and customer comments. A clearer roadmap for the second half of the year would help markets judge whether May’s 60-jet performance marks a new baseline or a temporary spike driven by a burst of completed repairs.
Regulators will also play a role in shaping the delivery curve. Every aircraft affected by the wiring defect must meet safety and documentation standards before it can be released to customers. If authorities decide to increase sampling or require additional inspections, the process could lengthen, even if the physical repairs are straightforward. Conversely, if Boeing demonstrates consistent quality on reworked jets, sign-offs could accelerate.
For now, the May numbers offer a cautiously optimistic snapshot. Boeing has shown it can lift deliveries despite an ongoing remediation effort, while Airbus has capitalized on improved access to a key market. The coming months will test whether Boeing can build on that momentum, narrow the monthly gap, and reassure airlines that its production system is robust enough to support their growth plans. The answer will help determine not only the financial trajectory of both manufacturers, but also how quickly the global airline industry can refresh its fleets after years of disruption.
