More news on this day
Travelers using Brussels Airport face severe disruption on Thursday 12 March, as all departing commercial passenger flights are cancelled due to a nationwide strike over working conditions and pension reforms.

Nationwide Strike Forces Complete Halt to Departures
Belgium’s major trade unions have called a 24-hour national strike on Thursday 12 March, targeting multiple sectors including aviation, public transport and public services. In response, Brussels Airport has taken the unprecedented step of cancelling all commercial outbound flights for the day, citing safety and operational concerns as key reasons for the move.
Airport management said the decision was taken in consultation with airlines after it became clear that large numbers of security screeners and ground handling staff would join the industrial action. With limited staff to manage security checks, baggage handling and ramp operations, the hub concluded it could not guarantee safe and orderly departures throughout the strike period.
The transport disruption is expected to affect between 165 and 250 scheduled departures that would normally leave Belgium’s busiest airport on a typical Thursday. Airlines have begun contacting affected customers directly with rebooking and refund options, but many travelers are still awaiting confirmation as schedules are reworked.
Arrivals, Charleroi Flights and Wider Transport Disruption
While all departures from Brussels Airport on 12 March are cancelled, arriving flights are not being automatically grounded. The airport has warned, however, that cancellations and significant delays are likely for some inbound services, as airlines adjust operations and aircraft rotations around the industrial action.
Brussels South Charleroi Airport, the country’s second major passenger hub and a key base for low-cost carriers, has gone further, announcing a full halt to both departures and arrivals on 12 March. The airport has said that a lack of available staff to operate safely during the national protest leaves no alternative but to suspend all commercial services for the day.
Travelers are also being advised to prepare for broader disruption across Belgium’s transport network. Rail and bus operators have signalled reduced or irregular services around the strike, including from the evening of Sunday 8 March, which could complicate access to and from airports on the days immediately before and after the walkout.
What Affected Passengers Should Do Now
Passengers booked to depart from Brussels Airport on Thursday 12 March are being urged not to go to the airport and instead to wait for information directly from their airline or travel agent. Carriers are progressively updating their systems, and in many cases are offering free date changes, alternative routings from nearby airports or refunds in line with their own policies and European air passenger regulations.
Some international airlines, including long-haul operators, have already published travel waivers for Brussels, allowing customers to move their journeys to dates before or after the strike without change fees. Others are offering rerouting via alternative European hubs such as Amsterdam, Paris or Frankfurt, subject to seat availability. Low-cost airlines are also expected to rebook travelers on later flights where possible, though options may be more limited on highly seasonal or less frequent routes.
Passengers scheduled to arrive in Brussels on 12 March are advised to closely monitor their flight status in the 24 to 48 hours before departure and to build in extra time for any onward travel by train or bus in case of knock-on disruptions. Those with tight same-day connections, important events or cruise departures may wish to explore earlier arrival dates or alternative gateways to reduce the risk of missed plans.
Your Rights Under European Air Passenger Rules
Under European air passenger protection rules, travelers whose flights are cancelled are generally entitled to a choice between a refund of the unused ticket or re-routing at the earliest opportunity or at a later date that suits them, subject to seat availability. Airlines must also provide care and assistance in many situations, which can include meals and, if necessary, hotel accommodation when passengers are stranded away from home.
However, compensation payments for cancellation or long delay may not apply when the disruption is caused by extraordinary circumstances outside an airline’s direct control. Nationwide strikes that severely limit essential airport functions are often classified in this way, meaning travelers should not automatically expect the additional lump-sum compensation that is sometimes awarded after operational disruptions such as technical faults.
Experts recommend that passengers keep all receipts for any extra expenses incurred because of the disruption and contact their airline or booking agent first before making independent arrangements. Travel insurance policies, especially those including trip interruption or strike cover, may offer further protection, though coverage will depend on the specific terms and whether the policy was purchased before the strike was announced.
Planning Alternatives and Minimizing Disruption
With the strike date approaching, travelers still in the planning phase are being advised to avoid booking departures from Brussels Airport or Charleroi on 12 March. Those who must travel around that time may find more reliable options by departing on 11 March or waiting until 13 March, or by using nearby airports in neighbouring countries, depending on their route and flexibility.
For travelers who cannot change their arrival into Brussels on the strike day, building in generous time margins for onward journeys will be essential. Train connections to other Belgian cities and international links to destinations such as Paris, London or Amsterdam could also face cancellations or reduced timetables as the national action impacts railway staff and signalling operations.
Air travel analysts note that operational knock-on effects can persist beyond the official end of a strike, as aircraft and crews return to normal rotations. Passengers flying on 13 March should therefore also keep an eye on their flight status and be ready for schedule changes, even if services are expected to resume.
For now, the core message from airports and airlines is that passengers should not show up for a departing flight from Brussels or Charleroi on 12 March unless specifically instructed otherwise, and should rely on official airline communications and airport updates as the situation evolves in the coming days.
