Belgium’s three largest trade unions are staging a nationwide strike that could cancel half of all departing flights from Brussels Airport. The action marks the ninth union-led protest to hit the airport since the start of 2025 — and it’s rooted in a policy dispute that many pilots call absurd.

What happened at Brussels Airport?
Brussels Airport is bracing for significant disruption on May 12, 2026, when three of Belgium’s largest trade unions — Christian ACV, ABVV, and ACLVB — will lead a nationwide strike that could halt roughly half of all departing flights. The protest stems from a long-running dispute over pilot retirement laws: Belgian pilots are currently required to work until age 66, yet are forced to stop core flying activity at 65. Unions have described this situation as “absurd,” with Belgium’s pensions minister Jan Jambon suggesting the retirement age could be stretched to 67 instead of 66 (Euronews).
Strike details
Security screening staff and ground-handling personnel are expected to join the demonstration, compounding the impact on flight operations. Brussels Airport cancelled all departing services on March 12, 2026, due to similar industrial action, and the May 12 action will mark the ninth union-led disruption at the airport since the start of 2025 (AirHelp). While arriving flights should face limited disruption, onward connections may be affected.
Ryanair cabin crew based in Belgium previously cancelled 107 flights from Brussels South Charleroi during a separate strike action (Aviation24.be). Budget carriers are particularly vulnerable to staffing disruptions.
Previous incidents
The pattern of recurring Belgian strikes reflects ongoing tensions over public sector pension reforms. At least eight trade union strikes have impacted Brussels Airport since the start of 2025 before the May 12 action (Euronews), suggesting this is not an isolated incident but part of a broader labor dispute that travelers will need to monitor.
Bottom line: Brussels Airport has faced repeated disruption from union action, and the May 12 strike looks set to continue that pattern — with roughly 50% of departures likely cancelled.
Which airports are reducing flights due to the shutdown?
Brussels Airport (BRU) will bear the brunt of the May 12 disruption, with departures expected to be halved. Charleroi Airport (CRL), Belgium’s secondary hub, is also likely to face full or partial closure during the strike.
Brussels Airport (BRU)
As Belgium’s primary international gateway, Brussels Airport is working with security contractors, ground-handling companies, and public authorities to preserve essential operations during the May 12 protest (AirHelp). Despite these efforts, approximately half of all departing flights are expected to be cancelled. Arrivals should face limited disruption, though connecting passengers should check their onward journeys.
Charleroi Airport (CRL)
Charleroi Airport, which primarily serves low-cost carriers, has historically closed entirely during national strike days (Aviation24.be). Budget airline passengers flying out of CRL should prepare for potential full flight cancellations and seek rebooking options well in advance.
Public transport services including Belgium’s national railway (SNCB) and De Lijn bus and tramway may also face disruptions on May 12 (Euronews). Travelers relying on ground connections to Brussels Airport should build extra time into their journeys or consider alternative transport.
Is it safe to go to Brussels right now?
For travelers with non-refundable bookings or essential travel needs, Brussels remains accessible during the strike period, though careful planning is required (Euronews). The strike itself is a planned, legal industrial action rather than civil unrest, but protest areas in central Brussels may experience localized disruption.
Travel advisories
Before traveling to Brussels during the May 12 strike, monitor airline notifications and airport status pages for real-time updates. If your travel is flexible, consider rescheduling to avoid the disruption entirely.
Safety areas
The airport itself and main transport corridors should remain accessible, though congestion is likely. Central Brussels areas near government buildings and major squares are typical gathering points for union demonstrations — travelers should monitor local news and avoid these zones during peak protest hours.
Brussels Airport has extensive experience managing strike days and typically maintains essential operations. Travelers should not automatically assume airport closure but should anticipate significant schedule changes and build flexibility into their plans.
What happens if my flight is cancelled because of a strike?
The question of compensation during strike-related cancellations is more nuanced than many passengers realize — and the ongoing reform of EU passenger rights legislation adds another layer of complexity.
Passenger rights
Under current EU Regulation 261/2004, passengers can receive compensation ranging from €250 to €600 depending on flight distance if they arrive three or more hours late. The compensation structure breaks down as: €250 for flights up to 1,500 km, €400 for flights between 1,500–3,500 km, and €600 for flights over 3,500 km (ReFly).
However, compensation under EC 261 is unlikely in most cases for the May 12 cancellations because the disruption involves airport-service staff rather than airline staff (AirHelp). Airlines should still provide rerouting or refunds and care (food, refreshments, accommodation) even if direct compensation does not apply.
The European Union’s General Court strengthened air passengers’ rights in March 2026, clarifying when travelers are entitled to financial compensation (Jurist). The court ruled that an airline’s autonomous decision to wait for passengers due to security shortcomings can break the causal link between extraordinary circumstances and flight delay, potentially expanding compensation eligibility in certain scenarios.
Rebooking options
Iberia has already issued free rebooking for passengers traveling between Madrid and Brussels ahead of the May 12 strike. Other airlines are expected to follow suit. Passengers whose flights are cancelled should contact their airline directly to request rerouting at no additional cost or a full refund.
Airlines warn that stricter passenger rights rules under revised EU261 could lead to cancellation of regional routes (EU Perspectives). The balance between passenger protections and airline viability remains a key tension in Brussels’ legislative debates.
Which areas should I avoid staying in Brussels?
For travelers staying in Brussels during the strike period, proximity to typical protest routes can mean unexpected delays. Union demonstrations typically gather near the European Quarter and central government areas.
Local safety tips
Book accommodation near major transport hubs if your stay will coincide with May 12. Keep digital and physical copies of your travel documents accessible. Register with your embassy if you’re an international visitor. Avoid walking near large gatherings if you’re uncomfortable with crowds.
Strike impact zones
Areas around Rue de la Loi, the Schuman roundabout, and the area near Brussels Central Station are common demonstration gathering points. Hotels in outer districts or near the airport may offer more predictable access during strike days, albeit with less central location.

What authorities are saying
Security screening and ground-handling staff are expected to join the nationwide trade union demonstration on May 12, 2026. Brussels Airport is working with security contractors, ground-handling companies, and public authorities to preserve essential operations.
— AirHelp flight disruption analysis (AirHelp)
The strike is rooted in grievances over Belgian retirement age laws requiring pilots to work until age 66. Unions argue pilots face an “absurd” situation: obliged to work until 66 but forced to stop core flying activity at 65.

The bigger picture: EU passenger rights reform
While the May 12 strike plays out on the ground, a parallel debate unfolds in Brussels’ legislative corridors. The EU is currently reforming Regulation 261/2004, with significant implications for passenger compensation standards.
The European Parliament supports maintaining the three-hour delay threshold for compensation eligibility and proposes preserving compensation amounts between €300 and €600 depending on flight distance. The European Parliament’s reform proposal even allows passengers to arrange their own transport if airlines do not offer timely alternatives, with reimbursement up to 400% of ticket price (European Parliament press release).
In contrast, the EU Council of Ministers proposes raising the delay threshold to four hours for short flights and six hours for longer flights, while reducing maximum compensation to €500 (ReFly). The reform proposal also aims to introduce free carry-on luggage for all passengers and tightens complaint-handling procedures for airlines (European Parliament Research Service briefing).
The implication: Travelers today face a patchwork of protections that may narrow or expand depending on which institution’s position prevails. Those facing May 12 disruptions should claim their current entitlements promptly — the legislative landscape could look different within months.
Summary
For passengers with May 12 travel plans through Brussels, the situation is clear: rebook now or prepare for significant disruption. The ninth strike action at Brussels Airport in fifteen months reflects deep-seated tensions over Belgian pension policy that show no immediate signs of resolution. While direct EC 261 compensation may be unavailable due to the strike’s classification, airlines must still provide alternative arrangements or refunds. Travelers should monitor their airline’s notifications, explore rebooking options immediately, and factor in potential ground transport disruptions on the day.
The ongoing EU reform debate will shape future protections — but for those affected next month, the window to act is closing fast.
