DUBLIN- Ryanair (FR) chief executive Michael O’Leary said passengers should brace for widespread disruption if French air traffic controllers resume industrial action from late spring. Speaking at the airline’s third-quarter briefing on January 21, he argued that staffing shortages, not infrastructure limits, remain the core cause of delays across French airspace.
O’Leary added that weekend absenteeism during the peak schedule has become a recurring issue rather than an exception. He said any reduction in French air traffic control availability quickly cascades across Europe, given the country’s central role in regional airspace flows.
Ryanair Impacted By French ATC Strikes
French air traffic control strikes have repeatedly coincided with peak travel periods, amplifying their impact on airlines and passengers.
In early July last year, coordinated walkouts disrupted the end-of-school holiday rush and forced carriers to cancel hundreds of flights.
Ryanair alone cancelled at least 170 services during the two-day action, affecting more than 30,000 passengers. According to Eurocontrol data, French air traffic control accounted for 31 percent of all ATC-related delays in Europe during summer 2025, the highest share on the continent.
According to Connexion France, O’Leary described the resulting restrictions as avoidable, stating that controllers simply failed to report for duty during critical operating windows.
He argued that such actions create artificial capacity limits that ripple through airline schedules.
Europe Travel Disruption
Disruption linked to French strikes extends far beyond flights departing from or arriving in France.
Aircraft transiting French airspace form a large share of north-south European traffic, connecting markets such as the UK, Spain, and Italy.
When controllers reduce capacity, airlines must reroute flights through Spanish or German airspace. These diversions increase fuel burn, extend flight times, and raise operating costs, which can lead to knock-on delays throughout the network.
O’Leary urged the European Union to adopt stricter oversight, including financial penalties for air traffic control providers that fail to staff the first wave of morning departures.
He said consistent staffing would significantly reduce disruption without requiring new infrastructure.
Ryanair France Capacity
Ryanair has already scaled back its French network in response to what it calls an uncompetitive operating environment.
The airline reduced flights to and from France by 13 percent during the winter 2025 schedule, citing higher taxes and persistent ATC disruption.
Further cuts are expected in summer 2026, particularly at regional airports, despite the carrier reporting record summer profits and rising passenger volumes.
Ryanair has, however, selectively restored some services, including routes between Tours and London Stansted and several UK links to Bergerac and Béziers.
The airline maintains that predictable air traffic control performance remains essential to sustaining capacity growth in France.
Bottom Line
Ryanair’s warning highlights ongoing structural challenges within European air traffic management, with France at the center of summer disruption risks.
Unless staffing reliability improves, airlines and passengers may again face delays, cancellations, and higher costs during the 2026 peak season.
