A breakdown that occurred this Sunday, May 18, 2025, at the Paris-Orly control tower resulted in a 40% reduction in air traffic.

A major technical incident affected the control tower at Paris-Orly Airport on Sunday, May 18. It caused significant disruption to air traffic. "Following a breakdown of the tower's systems early this afternoon, traffic regulation was imposed," indicated the Directorate General of Civil Aviation (DGAC).

Faced with this situation, the DGAC has asked airlines to reduce their flight schedules by 40% by the end of the day. Technical teams are working to restore systems and allow operations to return to normal. “DGAC teams remain fully mobilized”, assures the administration.

However, it remains too early to assess the impact of this outage on Monday. The situation is being closely monitored, and travelers are encouraged to check the status of their flights with the airlines concerned.

Paris-Orly is the capital's second busiest airport, with more than 33 million passengers welcomed in 2024, half the number recorded at Paris-Charles-de-Gaulle, according to figures from Aéroports de Paris (ADP).
