A senior air traffic controller has publicly criticized Ryanair (FR) and its chief executive (CEO), Michael O’Leary, for what they describe as “shameful” trolling of the air-traffic-control profession.
The controller’s open post, addressed to Ryanair aircrew and published on a pilot message board, said the industry has “had enough of O’Leary’s bashing and trolling of our profession”, reported PYOK.
Ryanair had claimed that Europe’s air-traffic-control (ATC) services are so overstretched that more than 30 million passengers have been affected by delays and cancellations so far this year.

Ryanair CEO Slammed by ATC
The controller challenged Ryanair’s portrayal of ATC failures, stating that many units were operating “beyond designed limits” intended to maintain maximum safety.
They argued that traffic levels have soared, and ongoing military conflicts have disrupted traditional air routes, making the job increasingly demanding.
Ryanair, on the other hand, insists that chronic understaffing and mismanagement within major ATC systems—particularly in France, Spain, Germany, the United Kingdom, and Greece—have led to severe disruptions.
The airline’s own “ATC Delays League” claimed that over 30 million of its passengers had suffered delays in 2025 alone. According to Ryanair, governments have failed to ensure adequate staffing, resulting in recurring operational breakdowns.

The ATC’s Perspective
In the open post, the controller rejected the idea that ATC professionals alone are responsible for delays and cancellations. They emphasized that controllers are “busting their asses every day” to maintain safety and order in increasingly crowded skies.
While acknowledging that ATC-related issues account for a portion of delays, they pointed out that weather remains the leading cause, responsible for roughly two-thirds of all disruptions.
The controller also highlighted that, although ATC agencies are recruiting heavily to meet demand, training is a time-consuming process that cannot be accelerated.
Becoming a fully certified controller can take two to three years, and shortcuts are not possible without compromising safety.

Ryanair Demands More Out of ATCs
Ryanair continues to call for reform across Europe’s air-traffic-control systems.
The airline wants the European Commission and national regulators to impose stricter performance standards and even fines for ATC providers that fail to meet staffing requirements—particularly during the “first wave” of early-morning departures.
The carrier has also launched a campaign website titled “Air Traffic Control Ruined Your Flight,” aiming to rally public support and pressure regulators to take action.
According to the airline, this initiative reflects the frustration of millions of passengers who have endured long delays and cancellations.

Operational and Safety Implications
Controllers argue that excessive workloads and persistent staff shortages are creating unsustainable pressure, potentially affecting safety margins.
Many units are operating under heavy strain, with controllers frequently required to reroute aircraft due to conflict-zone restrictions and weather-related airspace closures.
They warn that focusing solely on punctuality without addressing structural staffing and training issues could risk both safety and operational efficiency.

Bottom Line
The dispute between Ryanair and Europe’s air-traffic-control professionals highlights a growing divide in the aviation industry.
Airlines demand efficiency and punctuality to meet customer expectations, while controllers stress that maintaining safety and adequate staffing takes time and resources.
As the debate intensifies, the need for collaborative reform rather than public confrontation becomes increasingly urgent.
