A detailed impact assessment released on 17 December 2025 by industry site PNC-Contact, citing Eurocontrol data, calculates that the 3-4 July 2025 French air-traffic-controller strike cost European airlines €120 million. Of that, €73 million stemmed from 2,058 flight cancellations and €47 million from delay compensation, rerouting and crew-duty infringements.
The report reveals that 26 percent of French controllers participated in the 48-hour stoppage, which coincided with the start of the summer holiday rush. Paris-CDG, Orly and Nice bore the brunt, but ripple effects spread across European airspace as carriers rerouted around French FIRs.

Eurocontrol warns that repeated industrial action could jeopardise EU targets to cut aviation emissions by 55 percent by 2030, as longer routings added 6,400 tonnes of CO₂ over the two-day period alone. Airlines are urging the European Commission to revive discussions on minimum-service guarantees and mandatory arbitration.
For corporate travel budgets, the figures underscore the value of contingency clauses in airline-frame agreements and the importance of multimodal options—particularly for intra-EU hops under 700 km where rail can substitute on strike days.
