Fleet renewal is reshaping not only what airlines fly, but how intensively they use different aircraft across their fleets. Average aircraft utilization is a key productivity indicator, which has generally increased over time as airlines have become more efficient. It is also an important metric to help understand supply and demand balance. Using Cirium Fleets Analyzer data, this article examines how utilization trends differ across passenger aircraft generations and age groups, highlighting the growing divide.
Flying the future: new-generation aircraft lead utilization trends
While average flight hours declined across all major passenger aircraft types between June 2025 and June 2026, new-generation aircraft consistently maintained higher utilization levels and saw smaller reductions than their legacy counterparts, see the table below. (....)
