Most of the current “what happened in Brussels” conversation online is about major travel disruption on 12 March 2026 due to a nationwide strike in Belgium that is heavily impacting Brussels Airport and other transport.

Quick Scoop: What happened in Brussels?

  • Key Belgian trade unions have called a 24‑hour national strike for 12 March 2026, mainly over pension reforms and unpaid labour issues.
  • Brussels Airport has announced that all departing passenger flights are cancelled that day for safety and staffing reasons; some arrivals may also be cancelled or heavily disrupted.
  • Brussels South Charleroi Airport is also grounding all flights scheduled for 12 March because it cannot safely staff operations.
  • Public transport and other sectors across Belgium are expected to be affected, so disruption will not be limited to air travel.

In practical terms: if you were planning to fly out of Brussels on 12 March 2026, you should assume your flight is cancelled unless your airline tells you otherwise.

Why is this trending now?

  • The strike date (12 March 2026) is immediate, so travellers are scrambling for information and alternatives.

  • Images and posts of crowded terminals and confused travellers from past Belgian strikes are being reshared, adding to the sense of urgency.

If you’re travelling: what to do
