Belgium’s 24-hour general strike on 12 May has delivered the country’s air-transport sector its worst one-day shock since last summer’s ATC walk-out. By 07:00 local time, Brussels Airport had scrubbed roughly 55 % of its departures while Brussels South Charleroi Airport closed completely after failing to assemble the minimum safety and ground-handling teams required under EU Regulation 139/2014. Airlines unable to secure Belgian slots diverted flights north to Maastricht Aachen Airport in the Netherlands, which confirmed it would accommodate 15 extra passenger and cargo rotations during the day. The immediate business impact is acute. Long-haul operators such as Brussels Airlines, Emirates and United cancelled wide-body services, cutting more than 8,000 long-haul seats in 24 hours. Pharma exporters moving temperature-sensitive cargo through Brussels’ GDP-certified cool-chain facilities scrambled to re-book freight via Frankfurt and Amsterdam, adding at least 24 hours to delivery lead-times and jeopardising just-in-time vaccine shipments destined for West Africa. Mobility managers were urged to invoke “duty-of-care” protocols, rerouting travellers via Paris or London, where Eurostar and Thalys still had seats available, albeit at peak-fare levels. Brussels Airport’s own passenger advisory, published early on 12 May, warned of a knock-on surge on 13 May when stranded travellers attempt to re-book. The hub expects longer security and border-control queues because many federal-police officers participated in the strike, leaving staffing gaps that cannot be filled overnight. Companies with expatriate staff arriving for EU assignments later this week are therefore advised to build extra buffer time into Schengen stamping under the new Entry/Exit System to avoid overstays.

Should those same travellers need emergency visa extensions or completely new travel documents because of sudden reroutings, VisaHQ can streamline the process. Its dedicated Belgium portal (https://www.visahq.com/belgium/) lets mobility teams and individual passengers submit applications online, arrange express courier pick-ups, and track approvals in real time—an invaluable service when strikes compress timelines and raise the risk of inadvertent overstays.
In addition to passenger disruption, cargo handlers estimate that 480 tonnes of outbound freight—and €36 million worth of goods—could miss same-day connections. Multinationals are activating contingency clauses in service-level agreements that allow them to shift loads to alternate gateways without penalty. Logistics suppliers, however, warn that the Belgian action is rippling outward: warehouses around Liège reported backlog build-ups by mid-morning, and French road-haulage unions hinted they could stage solidarity slow-downs on arterial routes to the Channel ports. The broader lesson for mobility professionals is strategic: Belgium’s unions have succeeded in paralysing critical nodes nine times since January 2025, each time with less than a week’s notice. Global employers with headquarters or regional hubs in the Benelux should review business-continuity plans, pre-clear alternative routings with immigration counsel, and secure flexible corporate fares that allow same-day changes without hefty penalties. As one travel-risk manager at a Fortune 100 chemicals firm put it, “our playbook now treats Belgium as a high-volatility origin—on a par with France during ATC strikes.”
