Boeing surpassed Airbus in quarterly aircraft deliveries during the first quarter of 2026, with Boeing delivering 143 commercial aircraft compared to Airbus's 114, marking Boeing's best quarterly total since 2019 and its first delivery lead in years. However, this operational recovery masks deeper structural issues for both manufacturers. Airbus generated €12.7bn in revenue but suffered a 52% collapse in adjusted operating profit down to €300mn due primarily to production bottlenecks, particularly engine supply from Pratt & Whitney which is constraining the A320 ramp-up. Additionally, Airbus faced delays regarding roughly 20 aircraft for Chinese deliveries and quality issues requiring rework on fuselage panels for some A320 family units, pushing resolution timelines into the first half of the year. Despite delivering fewer planes, Airbus maintained a massive backlog of 9,037 commercial aircraft and saw relief from its Defence and Space segment which posted strong growth in revenue and operating profit, though CEO Guillaume Faury emphasized urgent priorities to "ramp up" production to hit a full-year target of 870 deliveries. In contrast, Boeing reported $22.2bn in revenue representing a 14% year-over-year increase, but the company continues to operate with significant margin compression as it works through years of disruption. Boeing posted a net loss of $7mn, a narrow improvement from $31mn the previous year, and an adjusted loss of 20 cents per share versus analyst expectations of 83 cents. The commercial division specifically recorded an operating loss of $563mn with a negative 6.1% operating margin, indicating that the company is converting more aircraft into revenue but struggling to achieve profitability on each unit due to elevated production costs, quality remediation expenses, and regulatory compliance requirements following past safety crises and the door plug incident. Looking forward, Boeing’s recovery remains tightly coupled with regulatory approvals from the Federal Aviation Administration (FAA) for any increases in production rates. The 737 program is currently producing at 42 aircraft per month with plans to increase output to 47 units monthly this summer pending further FAA sign-off on new variants like the 737 Max 7 and Max 10, which are expected to be certified later this year with deliveries beginning in 2027. The 777X program has also entered a new phase of flight testing after receiving regulatory authorization, with first delivery for the 777-9 also targeted for 2027, signaling meaningful but distant milestones in a turnaround effort that has stretched far beyond initial expectations.
