Airbus vs Boeing: Who Rules Aircraft Manufacturing Now?

Airbus is within striking distance of overtaking Boeing’s 737 as the most-delivered commercial aircraft in history. 

Aviation consultancy Cirium has reported that the Airbus A320 family trails by just 20 units, a gap that could be surpassed within a month.

This development is more than just a shift in leaderboard status. For the world’s most recognised aircraft manufacturers, it highlights how industrial scale, component reliability and supply chain responsiveness define performance in a sector driven by precision and volume.

Narrowbody output reflects production discipline

Aircraft manufacturing relies on highly synchronised supply chains. Both Airbus and Boeing depend on global networks to deliver thousands of components per aircraft – engines, avionics, control systems – with minimal margin for error. 

Any delay or quality issue in just one tier can hold up the entire production line.

Boeing aims to increase monthly output of its 737 MAX from 38 to 42 aircraft, followed by a move to 47 in early 2026. 

Chief Executive Kelly Ortberg told the Bernstein Strategic Decisions Conference: “We’re pretty confident in our ability to move from 38 to 42. 

“Now, after that, we do have subsequent rate increases in our plan, and they will typically be in that five-per-month rate. That feels like a good increment. So, the next one would be to 47.”

Kelly also confirmed the company has made progress in reducing quality issues, noting: “Virtually every one of our customers is reporting a higher quality of airplane at delivery.” 

The company has focused on quality control after the Federal Aviation Administration (FAA) capped output due to safety concerns, including an incident involving a cabin panel on a 737 MAX 9.

Airbus, meanwhile, maintains high-volume production of the A320 family, helped by a stable supplier network and consistent throughput. As of early August, it has delivered 12,155 A320 aircraft – just 20 behind the 737’s all-time total.

Technical setbacks test production stability

Despite its momentum, Airbus faces its own challenges. The A320neo uses Pratt & Whitney geared turbofan engines, marketed for fuel efficiency. 

However, flaws in high-tech coatings have increased maintenance intervals, grounding aircraft and creating a backlog at repair facilities. The disruption shows how technical performance at the component level can ripple through an entire manufacturing ecosystem.

Boeing also faces pressure to deliver on a substantial order backlog. In May, the company signed a US$200bn agreement with Qatar Airways for 160 aircraft – 130 787 Dreamliners and 30 777-9s – with options for 50 more. 

Scaling output to meet this demand requires tight coordination across suppliers producing high-value parts and specialised assemblies.

According to Reuters, Boeing spent US$2.3bn in cash during the first quarter. This financial strain adds complexity to any investment in production resilience or capacity upgrades. In contrast, Airbus’ stronger financial position gives it more freedom to invest in new technologies and future programmes.

At the Paris Air Show, Airbus Chief Executive Guillaume Faury said: “I have a lot of focus on preparing that next-generation of single aisle. We are very steady and very committed to this.” 

Airbus is reportedly considering an open-rotor engine design for a future A320 replacement, with service entry targeted for the mid-2030s.

Design evolution meets market pressure

Narrowbody aircraft like the A320 and 737 remain critical to global passenger networks, especially for short and medium-haul routes. Operators depend on them to reduce fuel costs, maximise utilisation and respond to shifting demand.

But scaling production in this segment requires balance. Overproduction risks surplus inventory and cost overruns, while underproduction frustrates airlines and undermines customer trust. 

Boeing’s FAA-imposed production limits show how regulatory oversight adds another layer of complexity to output planning.

Both Airbus and Boeing continue to avoid full redesigns of their narrowbody jets, opting instead for incremental upgrades. This strategy helps maintain supplier stability, but raises questions about how long the existing platforms can remain viable.

The A320’s early adoption of fly-by-wire controls and twin engine options helped it gain a technical edge. 

Boeing’s late-stage modifications to the 737, including the MCAS system, contributed to two fatal crashes and a 20-month grounding – issues that still affect its production rhythm and reputation.

Today, the A320 and 737 families make up nearly half of the world’s passenger jet fleet. Yet their design limitations are becoming more apparent. While new entrants like China’s Comac C919 show potential, global certification and supply challenges keep them out of the export market for now.

Airbus’ climb from a 1970s-era consortium to Boeing’s closest competitor reflects decades of coordinated manufacturing, engineering risk and investment in production discipline.
