A radar glitch at Milan’s Area Control Centre on June 28, 2025, triggered a sudden and widespread flight halt across northern Italy 🇮🇹, leaving thousands of travelers stranded and exposing serious weaknesses in the country’s air traffic control systems. The disruption, which lasted for nearly two hours, affected major airports in Lombardy, Piedmont, Aosta Valley, and Liguria, grounding or delaying over 300 flights and impacting both domestic and international travel. As authorities and airlines scrambled to respond, the incident raised urgent questions about the reliability of Italy’s aviation infrastructure and the rights of passengers caught in the chaos.
What Happened: The Radar Glitch and Its Immediate Impact

On Saturday evening, June 28, 2025, at around 8:20 p.m. local time, air traffic controllers at Milan’s Area Control Centre detected a serious malfunction in their radar transmission system. This radar glitch quickly led to a complete halt of all flights in and out of northern Italy’s busiest airports, including Malpensa, Linate, Bergamo, Turin, and Genoa. For nearly two hours, no planes could take off or land, and the airspace remained closed until 10:20 p.m. Full operations were not restored until midnight.
The radar glitch disrupted the flow of critical information—radar, weather, and technical data—from control towers to aircraft cockpits. This breakdown in communication made it impossible for air traffic controllers to safely manage flights, forcing ENAV, Italy’s air navigation service provider, to activate emergency protocols. According to ENAV, “The problem affected the connectivity that allows radar data to flow to the operations room, which is provided by an external telecommunications supplier, namely TIM (Telecom Italia).”
Scope of the Disruption: Airports, Airlines, and Passengers
The flight halt affected a large swath of northern Italy 🇮🇹, including the regions of Lombardy, Piedmont, Aosta Valley, and Liguria. The main airports impacted were:
- Milan Malpensa
- Milan Linate
- Bergamo
- Turin
- Genoa
Estimates suggest that between 300 and 350 flights were either grounded or delayed during the radar glitch. Major airlines such as Ryanair, easyJet, ITA Airways, SAS, TAP Air Portugal, and Aegean Airlines all faced significant disruptions. Thousands of passengers found themselves stranded at airports, with many unable to get immediate help or information from airlines or airport staff.
At Milan’s airports, emergency accommodations were set up, including 200 camp beds for those unable to leave. However, many travelers reported a lack of support, closed airport facilities, and confusion about when flights would resume. Rome’s airport authority advised people to avoid traveling to northern Italy 🇮🇹 unless absolutely necessary and to check with airlines before heading to the airport.
Technical Details: What Caused the Radar Glitch?
The root of the problem was a failure in the radar transmission system at Milan’s Area Control Centre, which is managed by ENAV. The glitch interrupted the flow of radar, meteorological, and technical data from control towers to pilots, making it impossible to safely direct air traffic. ENAV quickly switched to a satellite-based backup system to manage flights already in the air, but all new departures and arrivals were stopped to ensure safety.
ENAV explained that the issue was linked to connectivity provided by an external telecommunications supplier, TIM (Telecom Italia). However, TIM denied direct responsibility, stating that radar operations depend on several systems managed by different operators. TIM expressed confidence that ongoing investigations would clarify the exact cause and responsibility for the radar glitch.
Emergency Response and Restoration of Service
Once the radar glitch was detected, ENAV followed international safety protocols by halting all new flights and activating backup systems. The priority was to safely manage planes already in the air and prevent any risk to passengers and crew. After about two hours, at 10:15 p.m., air traffic controllers began gradually resuming operations. By midnight, flight schedules had returned to normal, but the effects of the disruption continued into the next day as airlines worked through the backlog of delayed and canceled flights.
Passenger Rights and Practical Challenges
Under European Union regulations, travelers affected by flight delays and cancellations are entitled to compensation and support, including meals, accommodation, and rebooking options. However, the practical reality at the airports was mixed. Some airlines were able to provide assistance, while others struggled due to the scale of the disruption and limited staff on hand. Many passengers reported difficulty finding information or getting help, especially late at night when airport services were reduced.
If you were affected by the radar glitch and flight halt, it’s important to:
- Contact your airline as soon as possible for rebooking and compensation.
- Keep all receipts for expenses such as meals, accommodation, and transportation.
- Check the official EU passenger rights page for detailed information on your entitlements: Your Europe – Air passenger rights.
Advice for Travelers: What to Do Next
For those planning to travel to or from northern Italy 🇮🇹 in the days following the incident, authorities recommended:
- Avoid traveling to affected airports unless your flight is confirmed as operating.
- Check flight status directly with your airline before leaving for the airport.
- Monitor airport websites and official social media channels for the latest updates.
