France’s Largest Air Traffic Control Union Confirms September Strike, Threatening Major Travel Disruptions

Union Confirms Strike After Talks Collapse

The SNCTA, France’s largest air traffic control union, announced a 24-hour strike from September 18 to September 19. Union leaders accused the Civil Aviation Authority of destroying trust and mismanaging negotiations, prompting controllers to walk out in protest.

Representing nearly 60% of France’s controllers, the SNCTA holds decisive power, and its strike will heavily disrupt European aviation traffic.

Widespread Flight Chaos Expected

Controllers at all French airports, including Charles-de-Gaulle, will participate, forcing airlines to ground flights and reroute others across Europe. Carriers warned passengers to check schedules constantly, as official cancellation lists will only appear two days before the strike begins.

Travellers flying between the UK, Spain, Italy, and beyond face delays, diversions, or cancellations as French airspace restrictions ripple outward.

Union Pushes Pay and Reform Demands

The SNCTA demanded inflation-linked pay rises and urgent reforms, calling the strike a necessary step after failed negotiations with management. Smaller union strikes in July cancelled thousands of flights, but September’s action will likely trigger far greater disruption across Europe.

Passengers should track flights closely, allow extra time for connections, and prepare backup plans to cope with long travel delays.
