Charleroi Airport Cancels Flights as Night ATC Strike Runs to October

Flights have been cancelled at Brussels South Charleroi Airport after air traffic controllers began a series of overnight strikes, a dispute that published coverage suggests could continue into early October and repeatedly disrupt late and early departures.

What’s happening at Charleroi and how long it could last

Published updates from Brussels South Charleroi Airport indicate the industrial action is tied to air traffic controllers working for skeyes, Belgium’s air navigation service provider. The job action is scheduled to take place during the night shift window, broadly described in coverage as running from 22:00 to 08:00, a period that can directly affect late-evening departures, night arrivals, and early-morning first-wave flights.

Multiple reports describe the disruption as potentially stretching from the night of September 16, 2026 through October 10, 2026 (inclusive). That timeline effectively creates a rolling risk of cancellations for more than three weeks, with impacts most likely when aircraft are scheduled near the start or end of the overnight strike window, or when delays push flights into the affected hours.

The airport has framed the situation as a “social action” affecting operations, and published notices have advised travelers to verify their flight status with their airline before heading to the terminal. For passengers, the practical reality is that even flights scheduled outside the strike window may be vulnerable if earlier delays compress the day’s operating plan.

Immediate impact: cancellations already underway

On Thursday, September 17, 2026, local reporting described about 40 flights to and from Charleroi being cancelled due to the overnight strike. Airport updates also referenced dozens of cancellations across the first strike night and the early morning that followed, reflecting how quickly a night-time stoppage can ripple into the next day’s departure bank.

Coverage has also highlighted that many affected services are operated by Ryanair, the dominant carrier at Charleroi. Because the airport’s schedule is heavily oriented toward low-cost point-to-point flying, even a limited window of reduced air traffic control capacity can lead to a visible concentration of cancellations on a single airline’s route map.

For travelers, the pattern to watch is not only whether a flight is scheduled during the strike hours, but whether it is a late rotation that commonly arrives after schedule or a dawn departure dependent on aircraft positioning the previous evening. Either scenario can elevate cancellation risk when overnight tower staffing is disrupted.

Why the strike is happening

Published coverage links the dispute to compensation and conditions associated with night work. Reports describe negotiations having faltered over allowances for controllers covering overnight shifts, with unions arguing for parity with arrangements in other units where a night allowance is paid, and skeyes describing the demand as a substantial increase.

The dispute sits within a broader backdrop of labor-related disruptions that periodically affect aviation in Belgium and elsewhere in Europe. Industry reporting over the past year has repeatedly shown how localized staffing actions, especially among air traffic control and airport operations personnel, can lead to outsized impacts because capacity constraints in the system are hard to replace at short notice.

In this case, the strike’s recurring, nightly format matters as much as the underlying dispute. A single day of disruption can often be absorbed with ad hoc measures and rebookings, but a multi-week period of predictable night stoppages can force airlines to pre-cancel flights to stabilize schedules, aircraft rotations, and crew duty times.

What passengers should do now

Charleroi Airport’s public guidance has emphasized checking flight status directly with the operating airline before leaving for the airport, and avoiding unnecessary travel to the terminal if a cancellation is confirmed. That advice becomes particularly important during multi-day disruptions, when airport staffing and processing capacity can also fluctuate as passenger flows become uneven.

Travelers with late-night departures or early-morning flights should review both the scheduled departure time and the broader itinerary context, including any inbound leg for the aircraft and the likelihood of day-of delays. If a flight is cancelled, airline-managed rebooking and refund pathways are typically presented digitally, and passengers may be offered alternative services on later dates rather than same-day replacements when night capacity is constrained.

Passengers connecting to onward ground transport should also plan for knock-on effects. Charleroi serves as a major low-cost gateway for Brussels and nearby cities, and late cancellations can create a secondary challenge around late-night or early-morning connections, including prebooked buses, shuttles, and airport parking reservations that may need to be changed.

What to expect through early October

With the strike action described in published coverage as continuing nightly through October 10, travelers should anticipate a rolling cycle of updates rather than a one-time disruption notice. Airlines may adjust schedules in batches, meaning cancellations for specific dates can appear progressively as operational planning firms up closer to departure.

Operationally, a night-time air traffic control strike can affect more than the flights that would normally move during the stoppage. Late arrivals that cannot be handled may be diverted or delayed, and aircraft that do not return to base as planned can trigger early-morning cancellations the next day, especially at airports like Charleroi where tight rotations are common.

For anyone traveling during the period, the most reliable approach is to treat the schedule as potentially fluid and to monitor airline communications regularly in the 24 to 48 hours before departure. If the dispute is resolved earlier than expected, airlines may reinstate some services, but published airport notices and recent cancellations suggest disruption planning remains necessary at least in the near term.
