Charleroi Airport Faces Prolonged Flight Disruption Due to ATC Strike

Charleroi Airport Hit by Extended ATC Strike Over Compensation Dispute

September 18, 2026 — Air traffic controllers at Belgium’s Charleroi Airport initiated a prolonged series of overnight strikes on Wednesday, September 17, 2026, leading to anticipated disruption for more than 800 flights. The industrial action stems from unsuccessful negotiations regarding compensation for night-shift work.

The Belgian air navigation service provider, Skeyes, confirmed that the strikes are scheduled to occur nightly from 10 p.m. to 8 a.m. between September 16 and October 10. This extended period of industrial action, covering more than three weeks, is expected to severely restrict normal air traffic operations during these hours.

Scope of Disruption

Skeyes estimates that a total of 832 flights could be affected throughout the strike period. This figure includes 487 morning services and 345 night flights, underscoring how overnight industrial action can have significant ripple effects on subsequent morning operations.

The interconnected nature of airline schedules means that the precise impact remains challenging to fully ascertain. An aircraft delayed or unable to operate a flight from Charleroi may subsequently be unavailable for several other services later in the day. Furthermore, flight crews can exceed legally permitted working hours, potentially forcing airlines to cancel or reschedule additional flights.

For passengers, this means that even those with flights scheduled outside the 10 p.m. to 8 a.m. strike window could experience delays if disruption spreads through airlines’ aircraft and crew rotations. The cumulative impact is significant due to the strike's multi-night duration; even if airlines adjust schedules for one day, the same operational challenge re-emerges the following night.

Root of the Dispute

The core of the dispute revolves around night-shift bonuses for air traffic controllers stationed at Charleroi. Negotiations aimed at reaching an agreement on this compensation failed, leading controllers to announce repeated strike action rather than a single, isolated walkout.

Air traffic controllers perform a safety-critical function, managing aircraft movements, coordinating arrivals and departures, and maintaining safe separation between aircraft. Due to the specialized training, licensing, and knowledge required for these roles, airports cannot simply replace striking controllers with other personnel. This inherent criticality gives industrial action by air traffic controllers the potential to create substantial disruption, even with a relatively small number of participating workers.

The dispute also highlights how negotiations involving aviation personnel can have far-reaching consequences beyond the employees and their immediate employer. Airlines, airport operators, ground-handling companies, and thousands of passengers can all be significantly impacted by disagreements over working conditions within the air traffic management system.

Operational Adjustments and Outlook

Airlines may attempt to mitigate the disruption by moving departure times outside the strike window, repositioning aircraft earlier, or adjusting their schedules in advance. While these measures can reduce cancellations, they cannot entirely eliminate disruption. Carriers also need to coordinate changes across their broader European networks, as an aircraft operating from Charleroi often has multiple flights scheduled during the same day, meaning a delay to its first departure can affect subsequent journeys involving different airports.

Skeyes has cautioned that the full effect on airline rotations remains unclear. The estimate of 832 affected flights represents the expected direct exposure to the industrial action; secondary delays and cancellations could extend beyond these services.

Unless a resolution is reached between the controllers and Skeyes, the repeated nature of the action means significant operational challenges are expected to continue at Charleroi Airport until the scheduled end of the strike period on October 10.
