Business travellers heading to Brussels this month face fresh disruption after Belgium’s three largest trade unions called a nationwide protest for Tuesday 12 May. In updated travel advice released on 1 May 2026, the UK Foreign, Commonwealth & Development Office (FCDO) warned that “international flights are likely to be heavily affected, with potential cancellations at short notice,” and urged passengers to monitor carriers closely. Brussels Airport separately acknowledged that “a large number of departing flights will have to be cancelled,” while stressing that arriving services could also be hit.

If your itinerary still requires visa paperwork, VisaHQ can expedite the necessary Belgian documentation online (https://www.visahq.com/belgium/), sparing travellers the extra trip to consulates and giving mobility teams one less variable to worry about amid strike-day uncertainty.
The demonstration—targeting proposed pension-age reforms—will be the ninth strike to disrupt the airport since the start of 2025 and is expected to paralyse public transport across Belgium, from regional rail to city metros. Previous walk-outs caused security-checkpoint bottlenecks, baggage-handling slowdowns and missed connections for onward EU travel. Corporate mobility teams should prepare contingency plans now. Airlines have already opened re-booking windows or waiver policies, and some—such as Iberia—are encouraging customers to reroute via alternative hubs, albeit seat availability in neighbouring Amsterdam and Paris may prove tight once cancellation lists grow. Meeting planners with events in the EU quarter should consider hybrid formats or flexible attendance policies. Travellers unable to avoid the date are advised to allow extra time to clear check-in and to keep accommodation options near the airport or Brussels-South rail station on hold. Employers must also remember Belgium’s strict working-time rules: should staff be stranded, employers remain liable for per-diem subsistence and any overtime incurred while waiting for replacement flights. With summer peak season approaching—and unions signalling further action if talks stall—the 12 May protest underscores the need for real-time travel monitoring and robust duty-of-care protocols when scheduling Belgium-bound assignments.
