Air traffic control delays in Europe have doubled since 2015

by | Dec 9, 2025 | Connectivity

Research from IATA has found that air traffic control (ATC) delays in Europe have doubled over the past decade.

This increase has far outpaced the rate of traffic growth (6.7%), and affected 1.1 billion passengers. IATA estimates the delays have collectively cost the industry €16.1 billion since 2015. Delays due to weather and strikes were not covered in the analysis, which found staff shortages to be overwhelmingly responsible for ATC’s poor performance.

Staff capacity-related disruptions have increased by 179.7% and staffing-related delays by 201.7% since 2015. IATA Director-General Willie Walsh commented:

We’re now seeing the consequences of Europe’s failure to get a grip on air traffic control. A small, expected improvement in 2025 from a very bad 2024 does not change the deterioration that we have seen over the last decade. Airlines and travellers were promised a Single European Sky that would cut delays and reduce fuel burn through more efficient navigation and routes. Instead, passengers have seen delays more than double. 

10 of the 39 European Air Navigation Service Providers (ANSP) were responsible for 87% of all delays. France (DSNA) and Germany (DFS) alone were responsible for more than 50% of delays. These statistics demonstrate how a handful of countries are having a disproportionately negative impact on the continent’s ATC performance.

Walsh added:

While Eurocrats debate ways to increase the burden of EU261 passenger compensation, the root cause of much of the delay suffered by travellers—air traffic control—escapes without action or censure. And Europe’s connectivity and competitiveness suffer from schedules that must accommodate ATC inefficiency. It is completely unacceptable.
