Major Cyberattack Disrupts Check-in and Boarding at Brussels and European Airports: All You Need to Know

Major European airports, includingBrussels Airport, London Heathrow, and Berlin Brandenburg, experienced significant disruptions on Saturday, September 20, 2025, due to a widespreadcyberattacktargeting the service provider responsible for check-in and boarding systems. This cyber intrusion, occurring late Friday night, rendered automated systems inoperable across multiple hubs, forcing airport staff to switch to manual check-in and boarding procedures. The incident has led to extensive flight delays, cancellations, and long queues, deeply impacting the continent’s air travel sector and connected tourism industries.

Cyberattack Paralyzes Automated Passenger Processing Systems

The origins of the disruption trace back to a cyberattack on the software systems ofCollins Aerospace, a leading service provider supplying check-in, baggage drop, and boarding solutions to numerous airlines and airports globally. The company confirmed that itsMUSE softwareexperienced a cyber-related technical failure affecting airports in Brussels, Berlin, London Heathrow, and possibly others, though the full list remains undisclosed.

Automated self-service kiosks, electronic boarding, and baggage processing systems were impacted, compelling airports to resort to manual processing of passengers. This sudden shift significantly slowed departure procedures, creating bottlenecks and long wait times at security and boarding gates. Airports immediately advised passengers to arrive well in advance, two hours for Schengen flights and three hours for non-Schengen international departures, and urged travelers to confirm their flight status prior to arriving at terminals.https://www.reuters.com/en/cyberattack-causes-flight-delays-cancellations-brussels-airport-2025-09-20/

Widespread Disruptions Affect Flight Schedules and Passengers

Brussels Airport stated the cyberattack caused a “large impact” on the flight schedule, resulting in numerous flight cancellations and delays exceeding an hour for several departures. An estimated thirty-five thousand passengers were slated to fly from Brussels on Saturday, many experiencing longer check-in lines and uncertainty regarding flight departures. Brussels Airlines managed to implement alternative manual check-in procedures, especially for passengers with pre-issued boarding passes, to mitigate disruption impact where possible.

Heathrow Airport, the busiest in Europe, reported facing delays primarily affecting departing passengers whose check-in and boarding systems rely on the compromised service. The airport deployed additional staff to manage passenger flow and minimize disruptions but still experienced notable operational strain.

Similarly, Berlin Brandenburg Airport disconnected its systems from the affected service provider to contain the disruption, leading to extended waiting times and flight schedule adjustments. Other major hubs such as Frankfurt and Zurich airports confirmed they were not affected by the cyberattack, highlighting the targeted and partial nature of the incident.https://www.cbsnews.com/news/cyberattack-european-airports-london-berlin-brussels/

Implications for European Tourism and Travel Industry

The attack comes at a critical time as Europe witnesses a resurgence in tourism and air travel demand following easing of pandemic-related restrictions and growing global connectivity. The cyberattack’s disruption of major transit hubs profoundly impacts not only business and leisure travelers but also complex tourism supply chains linking Europe’s cultural, historical, and natural destinations.

Delayed and canceled flights affect inbound and outbound tourism flows, leading to economic consequences for airlines, airports, hospitality providers, and local tourism-dependent economies. Airports serve as gateways to countries’ tourism markets; thus, operational interruptions ripple through downstream service industries such as ground transport, accommodation, restaurants, and attractions.

Moreover, the incident underscores the growing vulnerability of critical infrastructure within the tourism and transportation sectors to cyber threats. Strengtheningcybersecurity resiliencein airports and related service providers has become a paramount concern for regulators, governments, and industry stakeholders. Such incidents threaten traveler confidence and could potentially deter tourists sensitive to travel disruptions, impacting long-term tourism growth and recovery prospects.https://www.tasnimnews.com/en/news/2025/09/20/3403598/cyberattack-causes-disruption-at-european-airports-including-heathrow-brussels

Airport Authorities’ Response and Mitigation Efforts

In response, Brussels Airport and other impacted hubs have activated emergency protocols, deploying more personnel to assist passengers and maintaining manual check-ins and boarding until system restoration. Communication channels with airlines and passengers are being amplified to provide real-time updates, reducing confusion and managing traveler expectations.

The unnamed service provider is working to identify the cyberattack’s root cause while implementing corrective patches and system restorations. Both the Federal Aviation Administration (FAA) and European aviation cybersecurity agencies are closely monitoring the situation to ensure network security and prevent further incidents.

Passenger advisories emphasize verifying flight confirmation before departure for the airport and adhering strictly to recommended arrival times to ease operational capacity constraints. Airports advise travelers to stay informed via official airline channels and airport notifications.https://www.firstpost.com/world/major-european-airports-including-londons-heathrow-face-delays-after-cyberattack-on-check-in-systems-13935430.html

Cybersecurity in Travel: A Rising Priority for Tourism Sector

This high-profile cyberattack is a wake-up call highlighting how essential cybersecurity is for safe, efficient air travel and sustainable tourism development. As airports become increasingly digital and interconnected, holistic cybersecurity strategies are imperative. These efforts include protecting passenger data, securing operational technologies, and assuring system redundancies capable of maintaining service continuity during disruptions.

Tourism stakeholders, including governments and international organizations like the International Air Transport Association (IATA) and the European Union Aviation Safety Agency (EASA), are expected to accelerate initiatives focusing on cyber threat intelligence sharing, staff training, and investment in resilient IT infrastructure to safeguard European and global tourism hubs.
