UK Tourists Face Major Disruption as Brussels Airlines Cancels Flights on 12 May: What You Need to Know

Thousands of British holidaymakers and business travellers are bracing for significant disruption this month, as Brussels Airlines confirms it will cancel approximately 60% of its flights on Tuesday, 12 May 2026, following a nationwide industrial strike in Belgium.

Brussels Airlines has confirmed it will cancel a large number of its scheduled flights on 12 May 2026 due to a nationwide industrial strike in Belgium. UK travellers with plans to fly through Brussels are being urged to check their bookings without delay, as the disruption is expected to have a considerable impact on flights operating to and from Britain. Passengers travelling through London Heathrow, Manchester, and Edinburgh are among those most likely to be affected.

Belgium's major national trade unions have called a nationwide strike on 12 May in protest against the federal government's proposed pension reforms and broader economic policy changes. The action is not targeted specifically at the aviation industry, but the knock-on effect for air travel is severe.

Key airport workers — including security staff, ground handlers, and check-in personnel — are expected to join the walkout, leaving Brussels Airport significantly understaffed and unable to operate at anything close to normal capacity. Brussels Airlines, though not directly involved in the dispute, has confirmed it will be cancelling a large number of its flights for the day as a direct consequence.

What makes this particularly frustrating for travellers is that this is far from a one-off situation. This strike is the latest in a series of nationwide walkouts that have repeatedly disrupted operations at Brussels Airport since early 2025, with no sign of the underlying political tensions being resolved any time soon.​​​​​​​

If your flight is cancelled, you are entitled to a choice between a full refund or a free rebooking onto the next available alternative flight. You should not be charged any additional fees for making this change when the cancellation is the airline's doing.

Beyond that, if you find yourself stuck at the airport facing a lengthy delay, airlines operating under EU Regulation 261/2004 — which continues to protect UK passengers travelling on EU-based carriers — are required to provide a reasonable standard of care. This includes meals and refreshments in line with your waiting time, and hotel accommodation should an overnight stay become unavoidable.

It is important to be aware, however, that because this disruption stems from a third-party strike rather than the airline's own workforce, financial compensation on top of a refund is unlikely to apply in most cases. Your strongest entitlements here are the right to a refund, a free alternative flight, and practical care while you wait.

Do not wait to hear from your airline. Visit your airline's official website or app and check your booking status today. Many airlines are expected to issue travel waivers in the coming days, allowing affected passengers to change their travel dates without penalty — but alternative flights will fill up quickly, so acting early is essential.

If you do end up paying out of pocket for meals, transport, or accommodation as a result of the disruption, keep every receipt. These reasonable expenses can typically be claimed back from your airline after the fact.
