The Shift from Airline Efficiency to System Constraints: U.S. Airline Operational Performance (2022-2024)
by HAVADER Editör Ekibi
A flight delay can be annoying, but have you ever wondered whose "fault" it actually is — the airline's, the weather's, or the airport system's? This study systematically answers that question for U.S. airlines using three years of data.
Airline operational performance is directly affected by delays and cancellations. This study's goal was to comparatively analyze performance changes from 2022 to 2024 using key indicators like on-time performance, cancellations, diversions, and delay causes — air carrier, weather, security, the National Airspace System (NAS), and late-arriving aircraft.
The results reveal a clear seasonal pattern across all three years: average on-time rates rose from 76.3% in 2022 to 78.3% in 2023, slipping slightly to 78.0% in 2024 — with 2023 the best-performing year overall. Peak performance occurred in October 2022, November 2023, and October 2024, while the lowest levels appeared in December and July. But the truly notable finding is how delay components shifted over time: air carrier delays decreased, while NAS delays and late-arriving-aircraft delays gradually increased.
What this study contributes is shifting the "who's responsible for delays" debate away from hunting for a single culprit, toward revealing a systemic shift: as airlines' own operational performance improves, the problem is increasingly moving toward airport infrastructure and the broader air traffic management system. An everyday analogy: it's similar to city traffic congestion no longer stemming from drivers' bad habits, but from roads that simply can't handle the number of vehicles — even if individual actors (airlines, drivers) improve, the system itself can become the bottleneck.
In the end, this research sends a clear message to aviation policymakers: future investment in reducing delays should target air traffic management infrastructure and system capacity, rather than airlines' own operations alone.
