Brussels Airport cancellations vary by ground handler during union action
Some flights at Belgium’s Brussels Airport were cancelled during union action on 9 October local time.
The airport did not close entirely, and the impact varies according to the ground handler used by the airline.
Why flights at the same airport can face different outcomes
The airport’s official notice said some Alyzia ground-handling staff were expected to join the action. Ground handling supports operations through tasks around aircraft and baggage. The airport expected more than half of Alyzia-handled flights to operate as planned. It expected no impact on Aviapartner-handled flights based on information available then, so the airport name alone cannot establish whether a flight is cancelled.
The 140 flights and 40% have different denominators
The Brussels Times reported 140 cancelled flights on 9 October. It also reported that Brussels Airlines would cancel 40% of its own flights to and from Brussels. That percentage concerns the airline’s scheduled services, not all airport flights. The 140 figure belongs to that report’s observation point and should not be presented as a final end-of-day total.

Airline messages and airport listings serve different roles
The airport said affected airlines were contacting passengers about flight status and options. Its flight overview displays cancellations only after the airline registers them, so an absent cancellation entry does not guarantee operation. Check the airline’s latest message using the booking reference and flight number, then compare the airport listing. The reviewed material does not establish a universal rebooking time or refund entitlement for every passenger.
The separate 12 October action may affect the journey to the airport
A separate public-services union action is planned for 12 October. The airport currently expects no impact on flights but anticipates public-transport disruption. Check current information from De Lijn, STIB/MIVB and NMBS/SNCB for the airport journey. Do not turn the 9 October disruption into a prediction of total cancellations on the 12th; conditions can change. Direct downloading of the airport notice was restricted, but its official text was checked through the web search tool and compared with independent reporting.
