If you flew through Brussels Airport this year, chances are you felt it. Missed flights, last-minute cancellations, packed terminals and mounting frustration became part of the routine in 2025, as strike action repeatedly brought Belgium’s main airport to a halt.
New figures now put a clear number on the disruption. According to data shared by MP Kjell Vander Elst (Open VLD), strikes at Brussels Airport led to the cancellation of 2,395 flights over the past year, directly affecting around 330,000 passengers.
For many travellers, those numbers reflect very real experiences – holidays delayed or cancelled, business trips missed and hours spent waiting for updates that often came too late.
Seven strike days, thousands of cancelled flights
In total, seven days of strike action were recorded at Brussels Airport in 2025. That may not sound like much on paper, but the impact was significant.
Earlier this month, Brussels Airport itself revealed that 275,000 passengers had already missed a flight this year as a result of industrial action. The knock-on effect goes well beyond the terminal walls. According to the airport, the disruption has cost the Belgian economy close to €175 million.
Vander Elst described the situation bluntly. “Each strike day represents a loss of around €25 million for our economy,” he said. But for him, the real damage is not only financial.
“What worries me most is the long-term impact on the airport’s reputation,” he added. “Reliability is everything in aviation, and once passengers and airlines lose confidence, it’s very hard to win it back.”
Political tensions and rising aviation taxes
The scale of the disruption has also reignited political debate around how Brussels Airport is being managed – and taxed.
Vander Elst criticised what he sees as mixed signals from government. While the Flemish government is reportedly taking on €3 billion in debt for high-profile projects linked to the airport, he pointed to decisions at federal level that, in his view, undermine competitiveness.
Under the current budget agreement, the federal government plans to raise the departure tax to €10 per passenger from 2027. That tax had already been increased from €2 to €5 last summer.
“For airlines and passengers, this makes Brussels less attractive compared with nearby airports,” Vander Elst argued. “You can’t on one hand talk about strengthening the airport, and on the other make flying from Belgium more expensive and less reliable.”
For passengers, the debate may feel abstract. But higher taxes and repeated strikes ultimately feed into ticket prices, route decisions and the willingness of airlines to keep investing in Brussels.
Brussels Airlines urges dialogue, not paralysis
Amid growing frustration, Brussels Airlines has tried to strike a more conciliatory tone. In a statement released on Friday, the airline said it does not expect the seven strike days seen in 2025 to happen again in 2026.
The carrier called on trade unions and the government to sit down together and look for solutions, stressing the economic importance of Brussels Airport not just for aviation, but for the country as a whole.
Brussels Airlines also urged all parties to consider alternative ways of protesting that do not completely paralyse the airport each time industrial action is called. The airline suggested that, given the airport’s role as a critical piece of infrastructure, the idea of a guaranteed minimum service should no longer be taboo.
Such systems already exist in other countries and sectors, designed to protect essential services while still respecting the right to strike.
Passengers caught in the middle
For the hundreds of thousands of travellers affected this year, the debate over politics, taxes and labour relations offers little immediate comfort. What they remember are cancelled flights, rerouted journeys and uncertainty at the gate.
As Brussels Airport looks ahead to 2026, there is broad agreement on one point: a repeat of 2025 would be damaging – not just economically, but reputationally.
Whether that means changes in how strikes are handled, renewed dialogue between unions and government, or a rethink of aviation taxes remains to be seen. What is clear is that Brussels Airport cannot afford to be seen as unreliable in a region where passengers and airlines have plenty of alternatives.
For now, the hope – shared by airlines, politicians and travellers alike – is that the turbulence of 2025 proves to be an exception, not a new normal.
