Ryanair slams Europe’s worst air traffic control providers, urges EU reform

Ryanair has called on EU governments to urgently reform their national air traffic control (ATC) systems, after publishing its “June League of Delays”, which reveals the worst and best ATC performers in Europe so far in 2025.

From January to June 2025, France, Spain, Germany, Portugal, and the UK were responsible for the most Ryanair flight and passenger delays due to ATC issues. France topped the list with over 26,000 delayed flights and 4.7 million impacted passengers. In contrast, Slovakia, Denmark, Ireland, Belgium, and the Netherlands reported minimal delays, thanks to better ATC management and staffing.

Ryanair CEO Michael O’Leary criticised national Transport Ministers for allowing underperformance to persist in major markets despite generous airline funding. He stressed that well-managed ATC systems in smaller countries prove that efficient operations are possible.

The airline accuses the worst-performing ATC providers of operating as “protected State monopolies” with little regard for passengers or accountability. Ryanair is encouraging travellers to visit its “Air Traffic Control Ruined Your Flight” webpage to demand action and pressure ministers to improve ATC staffing and efficiency, especially ahead of the busy summer travel season.
