A major cyber attack European airports faced on September 19 and 20, 2025, has caused widespread travel disruption and chaos across the continent. The coordinated attack targeted essential airport systems, crippling automated check-in counters, baggage handling operations, and electronic boarding services. With the digital infrastructure suddenly offline, airports were forced to fall back on manual procedures—staff writing out baggage tags by hand, boarding passes printed on emergency backups, and security lines moving at a fraction of their normal pace.
The impact was immediate and visible. Thousands of passengers were left stranded in departure halls, many missing connections or seeing their flights canceled entirely. Long queues snaked through terminals at London Heathrow, Brussels Airport, and Berlin Brandenburg, three of the hardest-hit hubs. Airlines scrambled to rebook travelers while airport authorities urged patience, warning that delays could stretch well into the weekend.

How the Cyber Attack Unfolded
The incident began late Friday night when critical passenger processing systems used by multiple European airports went offline. These systems handle essential functions such as:
- Check-in counters and kiosks
- Baggage tag printing and sorting
- Electronic boarding passes
- Gate management for boarding
When the systems failed, airports had to switch to paper-based and manual procedures. Long lines quickly formed as passengers waited for staff to process documents by hand.
Airports Hit the Hardest
Several major airports confirmed disruptions, with three hubs experiencing the greatest impact:
- Brussels Airport – Dozens of flights were delayed or canceled, with many passengers left in terminals waiting for updates. Staff reported check-in times taking three times longer than normal.
- London Heathrow – The UK’s largest airport struggled with long queues at all terminals. Automated bag drop machines stopped working, forcing travelers to queue for manual check-in.
- Berlin Brandenburg – Flights faced significant delays as staff worked to manage crowds with limited technology. Some departures were canceled entirely.
Other airports in Europe also reported slower service, though not all faced cancellations.
Impact on Airlines and Passengers
Airlines across Europe scrambled to adjust schedules, with ripple effects stretching beyond the continent. Flights to and from the United States were also delayed as crews waited for passengers held up by broken systems.
Passengers described chaotic scenes:
- Families stuck in security lines for hours.
- Travelers handwriting baggage tags while staff manually logged check-ins.
- Confusion over gate assignments as digital boards briefly went offline.
By Saturday morning, some airports had restored partial service, but the backlog caused delays well into the afternoon.
Authorities and Industry Response
Airport authorities confirmed that flight safety and air traffic control systems were not impacted. The disruption was limited to passenger services, meaning no risk was posed to aircraft in the air.
Technical teams worked through the night to restore the software, while airlines offered rebooking options to stranded passengers. Authorities in affected countries pledged to investigate the attack thoroughly, focusing on who was behind it and how similar incidents can be prevented in the future.
Why the Cyber Attack Matters
This cyber attack highlights vulnerabilities in international aviation. Many airports across Europe rely on shared technology platforms, meaning a single breach can ripple across multiple countries at once.
For U.S. travelers, the incident underscores the importance of being prepared when flying internationally. Delays in Europe can easily cascade into missed connections for flights heading to or from the United States.
Key concerns raised include:
- Overreliance on centralized technology providers.
- Limited capacity for airports to quickly switch to manual systems.
- Growing risks of cyber warfare targeting transportation infrastructure.
Advice for Travelers
For passengers heading to Europe or connecting through its airports, experts recommend:
- Check flight status often: Airlines are updating schedules hourly.
- Arrive early: Manual processing takes longer than automated systems.
- Travel light: Avoid checking large amounts of baggage to reduce delays.
- Stay informed: Use official airline apps or airport alerts for the latest updates.
The Road to Recovery
By late Saturday, many airports had restored partial services, though long lines and flight cancellations remained. It is expected that full recovery could take another day as systems are tested and brought back online
