How Airbus’ Supply Chain Power Is Disrupting Boeing’s Reign

For decades, Boeing’s 737 has been the world’s most-delivered commercial airliner. That dominance is about to end.

Airbus’ A320 series now stands just 20 units behind the 737, according to aviation consultancy Cirium and could surpass it as soon as next month.

The contest is about more than bragging rights. It highlights how supply chains influence production rates, quality standards and the future of aircraft design.

Both Boeing and Airbus depend on sprawling supply chains that stretch across continents.

Every aircraft requires thousands of components, from flight control systems to engines, all supplied on schedule and to precise standards. This reliance is why production numbers reveal so much about the health of each company’s supply chain.

Boeing aims to raise production of its 737 MAX from 38 aircraft a month to 42 and then to 47 by early next year.

Chief Executive Kelly Ortberg told the Bernstein Strategic Decisions Conference in May: “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 a 30% drop in production defects: “Virtually every one of our customers is reporting a higher quality of airplane at delivery.”

That improvement reflects Boeing’s effort to restore confidence after the Federal Aviation Administration (FAA) capped production in the wake of safety issues, including a panel incident on an Alaska Airlines 737 MAX 9.

Airbus, meanwhile, has proven it can sustain high-volume production. Its ability to close the decades-long gap with Boeing shows that its supply chain is responsive and flexible enough to handle consistent orders from airlines.

By early August, Airbus reported 12,155 lifetime A320 deliveries, with the gap against Boeing narrowed to just 20 aircraft.

Disruptions and resilience in production

Maintaining momentum in aircraft manufacturing is not only about speed. Safety, reliability and supplier stability all play a part.

Boeing’s troubles with the 737 MAX grounding forced it to prioritise quality, slowing output but preventing further crises. Supply chain partners had to adapt to these shifts, delaying deliveries but reducing risks.

Airbus is facing challenges of its own.

Its A320neo, equipped with fuel-efficient Pratt & Whitney geared turbofan engines, has been hampered by flaws in high-tech coatings. These flaws have increased maintenance needs, forced aircraft to the ground and backed up repair facilities. This shows that, even when aircraft design wins market favour, supply chain bottlenecks at the engine level can disrupt fleets worldwide.

Order backlogs also pressure supply chains. Boeing secured a US$200bn deal with Qatar Airways in May for 160 aircraft, including 130 787 Dreamliners and 30 777-9s, with options for 50 more widebody models. This is Boeing’s largest monthly order since 2023.

To deliver on that scale, it needs suppliers to keep pace with specialised components.

Reuters reported Boeing spent US$2.3bn in cash in the first quarter, underlining how financial strain complicates investments in supply chain resilience.

Airbus, with stronger finances, has greater freedom to invest in new designs and technologies. Bloomberg reported it is considering an open-rotor engine for a future A320 successor, which could enter service in the mid-2030s.

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

Demand shaping the future

Strong demand for narrowbody aircraft is what keeps pressure on both supply chains.

The A320 and 737 dominate global passenger traffic because they efficiently serve short and medium-haul routes. Airlines favour these jets to lower operating costs, adapt to fluctuating fuel prices and respond to shifting travel patterns.

But balancing production with demand is tricky. Overproduction risks financial losses, while shortages frustrate airlines and passengers. Boeing’s production caps imposed by the FAA show how regulatory oversight adds another layer of complexity.

Airbus and Boeing also avoid risky, full-scale redesigns of their narrowbody jets, opting instead for incremental updates. This strategy limits disruption across tiered supplier networks but raises concerns about whether a duopoly stifles innovation.

Airbus took early risks with the A320’s design, choosing digital fly-by-wire controls and offering two engine options. Those decisions helped the jet become a favourite with airlines, contrasting with Boeing’s troubled 737 MAX, whose MCAS software contributed to two deadly crashes and a 20-month grounding.

Today, both narrowbody families dominate nearly half of the global passenger jet fleet. Yet their evolutionary limits are clear, and both companies are looking ahead to the 2030s for next-generation models. China’s Comac C919 is a new entrant, but certification hurdles keep it from challenging Airbus and Boeing outside China for now.

The contest for the title of most-delivered airliner is about more than statistics. It reflects decades of supply chain adjustments, financial strategies and technical risks.

Airbus has climbed from a fledgling consortium in 1970 to a true rival, proving it can match Boeing’s scale.
