Aviation News Editor & Industry Analyst delivering clear coverage for a worldwide audience.
A national strike in Belgium on March 12 has halted all flights at Brussels and Charleroi airports, affecting 90,000+ passengers and prompting a United waiver.
Key Takeaways
- •Affects over 90,000 passengers as Brussels and Charleroi airports halt flights.
- •Prompts United Airlines to issue a travel waiver for its Brussels hub through March 19.
- •Marks the 8th national aviation strike to disrupt Belgium since the start of 2025.
- •Exempts airlines from EU261 monetary compensation but requires duty of care.
A national strike in Belgium on March 12 has forced a complete halt of departing flights at Brussels Airport (BRU) and a full 24-hour closure of Brussels South Charleroi Airport (CRL), causing widespread disruption for transatlantic carriers, including United Airlines. The labor action, the eighth to impact Belgium's aviation sector since the start of 2025, has affected an estimated 90,000 passengers and prompted United to issue a travel waiver for its key European hub.
In response to the strike, United Airlines implemented a travel alert for passengers scheduled to fly to, from, or through Brussels. The airline stated, "You can reschedule your trip and we'll waive change fees and fare differences... departing between March 11, 2026 and March 19, 2026." United typically operates three to four daily flights to Brussels from its hubs at Chicago O'Hare International Airport (ORD), Newark Liberty International Airport (EWR), and Washington Dulles International Airport (IAD).
Operational Impact and Airport Response
Brussels Airport, which handles an average of 500 flights daily, announced it would not operate any departing passenger flights for 24 hours. Airport authorities stated, "To ensure the safety of passengers and staff we have decided in consultation with the airlines not to operate any departing flights on 12 March." The decision impacted over 65,000 passengers scheduled to depart from BRU. Arriving flights faced significant delays and diversions, though a complete ban was not implemented.
Meanwhile, Brussels South Charleroi Airport, a major base for low-cost carriers, confirmed its complete closure for the duration of the strike, affecting more than 25,000 passengers. The airport cited "the lack of personnel present to ensure operations in complete safety" as the reason for the shutdown. The strike's impact extends beyond airport staff, with local public transport operators also facing severe service reductions, complicating access to the terminals for staff and passengers.
Key stakeholders were severely affected. Brussels Airlines, the home carrier at BRU, was expected to cancel over 200 operations. Low-cost carriers like Ryanair and Wizz Air, which rely heavily on CRL, were forced to cancel their entire flight schedules from the airport.
Under European Union regulations, the strike is considered an "extraordinary circumstance." This exempts airlines from paying fixed monetary compensation under EU Regulation 261/2004 (EU261). However, airlines retain a Duty of Care, requiring them to provide affected passengers with meals, refreshments, and accommodation if necessary.
A Recurring Pattern of Disruption
The March 12 strike is not an isolated incident but part of a persistent trend of labor disputes impacting European aviation. According to Brussels Airport historical records, Belgium experienced seven national aviation strikes in 2025 alone, which led to the cancellation of 2,400 flights and cost the economy an estimated €175 million.
This history has led to the adoption of preemptive operational strategies. The decision by BRU to implement a zero-departure policy reflects a growing trend among European airports to prevent terminal overcrowding and ensure safety ahead of planned strikes. A similar situation occurred during the Belgian National Strike of June 2022, when Brussels Airport also proactively froze its departure schedule. The April 2025 national strike provides a more recent parallel, which saw over 300 flights canceled at BRU and 120 at CRL due to widespread union actions.
What Comes Next
Airport authorities expect a resumption of normal flight operations at both Brussels Airport and Charleroi Airport on March 13, 2026, following the conclusion of the 24-hour strike. However, residual delays and knock-on effects may persist as airlines work to clear the backlog of passengers and reposition aircraft and crew. United Airlines' travel waiver, which allows for penalty-free changes, remains in effect for passengers scheduled to travel through March 19, 2026, providing a window for customers to adjust their plans.
Why This Matters
This latest strike highlights the significant operational vulnerability of major European hubs to coordinated labor action. For international carriers like United Airlines, recurring disruptions at a key gateway like Brussels create substantial financial and logistical challenges. The event serves as a critical reminder of the ongoing tensions between labor unions and governments in Europe and their direct, costly impact on the global aviation network.
