Disruption at Heathrow and European airports after cyber attack

On Saturday, 20 September 2025, a cyberattack took down the software used by several European airports to support check-in, boarding, and luggage processing. The software is provided by Collins Aerospace, an American aviation company and the world’s largest provider of aerospace and defence products.

The company, owned by RTX, released a statement announcing that it was “aware of a cyber-related disruption […] in selected airports” specifically targeting its Muse software.
