On Thursday, March 12, Belgium puts its blue overalls back on… and the country back on “pause.” A new union mobilization, the eighth since the beginning of 2025, is planned with a national demonstration in Brussels. For travelers, the message is as clear as a boarding siren: travel is about to get complicated, and significantly so.
First, the airline industry is taking the brunt of the impact. At Brussels-Zaventem Airport, the work stoppage by security and ground handling staff has forced management to cancel all passenger flight departures "for operational reasons." The same scenario is playing out at Charleroi-Brussels South Airport: no flights are departing. Arrivals will also be disrupted, airports warn. In short, if you had a ticket, it's best to check your email before looking at the departure boards.
When Belgium goes on pause, the economy coughs
On the airline side, the tone is polite but tense. SN Brussels Airlines, a subsidiary of the Lufthansa Group, says it "sincerely regrets the inconvenience caused by these industrial actions" and states that 100.000 passengers have already been affected by previous strikes in the sector. The figures from the airports are staggering: Brussels Airport has recorded 2.400 canceled flights and more than 275.000 affected travelers during past actions. This is no longer a minor setback; it's a system that's seizing up.
On the streets and on the railways, the day also promises disruptions. Public transport will be running at a reduced capacity in all three regions, with a cut-off service announced. Rail traffic, however, is expected to partially resume: unions want to facilitate the transport of demonstrators to Brussels after strikes that began on Sunday, March 8, and are scheduled to end Wednesday evening. A way of telling the reader: to come and protest, restrictions are being eased a little; to go on holiday, that's another story.
The ongoing tug-of-war between the right to strike and the continuity of services remains. Unions are hoping for a mobilization comparable to that of October 2025, when approximately 100.000 people (up to 140.000 according to some organizations) marched in the capital. Meanwhile, VOKA, the main network of Flemish business operators, is pushing for a minimum service at airports. Will Belgium, a country of compromise, finally resolve this sensitive issue, or will it continue to count canceled flights as if counting days of social unrest?
