A 24-hour general strike by Belgian trade unions on 12 May forced Charleroi Airport to shut entirely and cut Brussels Airport’s operations by more than half, prompting 15 passenger and cargo flights to divert to Maastricht Aachen Airport in the Netherlands.

For travellers suddenly rerouting through neighbouring countries, having up-to-date visa and transit information becomes critical; specialist platforms such as VisaHQ can streamline that process. The company’s Switzerland portal (https://www.visahq.com/switzerland/) offers real-time entry requirements and expedited processing, helping mobility managers quickly confirm whether employees need, for example, a Schengen airport-transit visa when flights are moved to Maastricht or Paris at short notice.
Scandinavian Airlines (SAS) and several other carriers issued travel alerts offering free rebooking for flights to or from Brussels on the day. Although no Swiss airports were directly hit, the disruption rippled across Lufthansa-Group scheduling hubs. Swiss International Air Lines warned corporate clients that connecting itineraries via Brussels were at risk of missed onward flights to Zurich and Geneva. Swiss tour operators advised passengers bound for the UK or USA to consider alternatives via Paris CDG, Frankfurt or direct services from Switzerland. According to Eurocontrol data from the morning of 12 May, 22 arrivals and 18 departures involving Swiss-booked passengers were cancelled or rerouted, affecting roughly 3,800 travellers. Rail operator SBB noted a 12 % spike in bookings on the Basel–Frankfurt ICE service, used as an alternative corridor to long-haul flights out of Germany. The incident underscores the increasing vulnerability of multi-hub travel itineraries to industrial action. Mobility managers are encouraged to map critical employee routes that rely on Belgian gateways and build contingency policies—such as dual-ticketing on rail and air or flexible hotel blocks in Paris and Frankfurt. Belgian unions ABVV, ACV and ACLVB say further strikes are possible if pension-reform talks stall. Companies with frequent Brussels traffic should sign up for IROPS (irregular operations) feeds and ensure travel-risk dashboards capture secondary impacts on Swiss-based staff.
