Belgium’s main international gateway is bracing for its largest operational shutdown in almost a decade. In a notice published on 7 March 2026, Brussels Airport (BRU) confirmed that **no passenger departures will be processed between 00:01 and 23:59 CET on Thursday 12 March** because the airport’s 900-strong privately-contracted security screening workforce will walk out for 24 hours. The work stoppage comes after wage talks between security companies G4S Secure Solutions and ICTS Europe and the three leading trade unions – ACV/CSC, ABVV/FGTB and ACLVB/CGSLB – collapsed on 5 March over night-shift allowances and retirement benefits. While arriving flights will be permitted to land, the airport operator says arriving passengers should expect “significant delays” at passport control as police will be redeployed from departure filters to arrivals processing. BRU handled 76,000 departing passengers on the equivalent Thursday last year; with all 415 scheduled departures now cancelled, airlines will either re-route customers via Amsterdam, Paris-CDG or Frankfurt, or offer date changes and refunds. Flag-carrier Brussels Airlines has already pre-emptively cancelled 186 flights and warned of a financial hit “in the low-to-mid single-digit millions” from compensation and reaccommodation costs. For corporate mobility teams the shutdown could not come at a worse time. The week of 11–15 March is the peak of Belgium’s spring conference season, with three EU Council working groups and multiple trade fairs in Antwerp and Ghent. Multinationals are scrambling to reroute delegates by high-speed rail or via regional airports such as Charleroi, Eindhoven and Lille. Freight forwarders moving time-critical pharmaceuticals report switching to Liège Airport’s cargo facilities, adding 90 minutes’ trucking per consignment. Employers with posted workers should review duty-of-care plans: Belgium’s Works Council dispute rules oblige companies to honour paid travel days if planned flights are cancelled for reasons outside the employee’s control.

Should those rerouted itineraries require unexpected transit or entry visas, VisaHQ can streamline the paperwork. The company’s Belgium portal (https://www.visahq.com/belgium/) allows travellers and corporate travel managers to check requirements in real time, submit digital applications and arrange courier collection, shaving days off traditional processing times and reducing stress during disruption.
Under Belgian law, airport security screeners must give only 48 hours’ notice of industrial action. The government has ruled out requisitioning military police, arguing that the dispute is a private-sector matter. Transport Minister Georges Gilkinet told Parliament he is “monitoring the situation” but called on both sides “to return to meaningful dialogue.” If mediation fails, unions have warned of rolling strikes through Easter. Practically, travellers booked on 12 March departures should: (1) await airline instructions before heading to the airport; (2) keep receipts for any reasonable extra costs; and (3) if urgent travel is essential, consider Eurostar or Thalys rail services, which are adding capacity on the London-Brussels-Paris axis. Employers should cascade contingency guidance and confirm that posted-worker notifications remain valid if employees reroute through neighbouring countries. The episode highlights the fragility of Belgium’s aviation ecosystem as it enters a bumper 2026 summer, when the new Schengen Entry/Exit System will already be slowing border processing. HR and travel managers may want to diversify routings for high-value assignments and build extra buffer days into mobility schedules.
