Airline Fleet Age by Airline: Rankings and Data
Booking a flight often means trusting a machine that has been in service for over a decade. The current global airline fleet age averages nearly 15 years, driven by supply chain constraints and differing business models. While some carriers fly ultra-modern jets, others rely on aging aircraft. Here is a look at the rankings.

How airline fleet age is measured
Fleet age is typically expressed as the median or mean time in service calculated from active delivery dates, with each carrier’s specific mix of aircraft factored in. Regional jets and wide bodies have very different lifecycles, so they need separate baselines. EUROSTAT and similar agencies track these figures globally; the current average sits at 14.8 years.
Global airline fleet age trend
The global average aircraft age has climbed to 14.8 years, up from 11.6 years in 2022. The main driver is supply chain disruption. With an industry-wide backlog exceeding 17,000 aircraft orders, carriers have little choice but to keep older planes flying far longer than originally planned.
Youngest airline fleets by carrier
Budget and regional operators tend to run the the youngest fleets. Wizz Air’s UK and Malta subsidiaries average 3.1 and 3.4 years respectively. In Asia, IndiGo’s fleet averages just 4.7 years, and STARTUP leads among regional carriers as the youngest operator overall.
Oldest airline fleets by carrier
Legacy carriers like Delta Air Lines and United Airlines operate some of the the oldest fleets, with averages reaching up to 16.7 years. At the far end of the spectrum, specialized remote operators fly equipment well beyond typical lifespans. Kenn Bore Air and Trans Maldivian Airways both operate aircraft averaging over 40 years in service.
Airline fleet age by region
Asia’s fleets are among the youngest globally, driven by large narrow body deliveries to carriers like IndiGo. Europe shows a steady renewal pattern as legacy carriers phase out older jets. Older fleets are more common in constrained markets, where island nations and remote cargo operators depend on proven, durable aircraft.
Fleet age by airline type
Operational model has a strong influence on fleet age. All-cargo carriers tend to run the oldest equipment, frequently exceeding 25 years on average, since freight companies rely heavily on converted passenger jets. Charter fleets also skew older. Scheduled passenger airlines, by contrast, renew their fleets at a much faster pace.
Why older airline fleets stay in service
The main reason carriers keep older aircraft flying is chronic supply chain shortages and delayed deliveries. There is also a practical dimension: established maintenance ecosystems for older types are well understood and predictable. Retiring functional aircraft too early can constrain capacity at exactly the wrong moment, limiting a carrier’s ability to grow.
Fleet age, fuel burn and emissions
Older aircraft burn more fuel and generate higher maintenance costs, both of which weigh on profitability. Replacing them reduces noise and emissions, which matters as airlines work toward industry decarbonization targets.
Largest airlines with mid-age fleets
Many of the world’s biggest carriers sit comfortably in the mid-age range, balancing scale without aggressive renewal cycles. American Airlines, for instance, operates hundreds of jets averaging 14.1 years. Southwest Airlines runs a similarly large narrow body network at a comparable age, showing that consistent operational reliability does not depend on having the newest airframes.
