Airlines are increasingly relying on maintenance and cabin refurbishments to keep aging aircraft, some over 25 years old, in regular service. While the latest cabin amenities can make even vintage planes feel modern, the aviation industry is facing supply chain challenges and delays that are slowing down interior upgrades. Carriers are finding ways to extend the lifespan of their fleets, from narrowbody workhorses to widebody jets, as new aircraft deliveries remain constrained.

Why it matters

As the average age of commercial aircraft rises, airlines must balance the need for fuel efficiency and maintenance costs with passenger expectations for a modern flying experience. This trend highlights the industry's resilience in the face of supply chain disruptions, but also raises questions about the long-term sustainability of an aging global fleet.

  • In the spring of 1991, United Airlines took delivery of four Boeing 767-300ER aircraft that are still in service today, over 25 years later.
  • Earlier this year, aircraft asset manager EirTrade Aviation purchased two 2021- and 2022-vintage Airbus A320neo aircraft with the intention of disassembling them for parts, rather than flying the planes.
  • In January 2026, United Airlines told pilots it anticipates needing to ground 12 of its older Boeing 777 aircraft this summer due to a lack of available spare parts.

What they’re saying

“Airplanes are built incredibly durably.”

— Nathaniel Pieper, Chief Commercial Officer, American Airlines

“When you fly long-haul, fuel burn becomes a major concern.”

— George Dimitroff, Global Head of Aircraft Valuations, Cirium

“It really doesn't matter how old the aircraft is. Disassembly really comes down to the economics and whether it justifies doing it.”

— Bill Thompson, Director, EirTrade Aviation

“Airplanes are little more than portable jet engine stands in today's market.”

— Courtney Miller, Aviation Advisor, Visual Approach Analytics

“The whole interior retrofit program has been affected.”

What’s next

Airlines will continue to invest in cabin refurbishments and maintenance to keep their aging aircraft fleets operational as they wait for new aircraft deliveries to return to pre-pandemic levels.

The takeaway

The aviation industry's ability to extend the lifespan of commercial aircraft through maintenance and interior upgrades highlights its resilience, but also raises concerns about the long-term sustainability of an aging global fleet as fuel efficiency and passenger expectations evolve.
