On October 16, 2026, air travel across Italy faced severe disruption following a major technical failure in the primary data transmission network supporting the national air traffic control system. Air navigation service provider ENAV identified overnight anomalies in the network that transmits data between key control systems. ENAV officially ruled out any cyberattack or malicious activity as the root cause of the outage.
To ensure safety as morning traffic expanded, ENAV transitioned operations to a secondary satellite backup network and imposed strict flow restrictions starting at 06:00 local time. These operational measures capped Italian airspace capacity at approximately 50 percent of normal volume during the morning. Capacity was gradually increased to 75 percent in the afternoon before full network functionality was restored and airspace capacity returned to 100 percent.
The capacity restrictions caused substantial disruptions at major hubs nationwide. By noon local time, aviation data firm Cirium recorded 192 flight cancellations across Italian airports. Overall on-time departure rates dropped to approximately 31 percent during the peak of the disruption, with Rome Fiumicino recording a 28 percent on-time rate and Milan Malpensa falling to 25 percent. Delays and cancellations were also reported at Milan Linate, Bergamo, Pisa, and Florence.
The technical failure coincided with previously scheduled industrial action, aggravating travel delays across the country. Disruptions were compounded by a 24-hour national strike by easyJet pilots and cabin crew in Italy, alongside local ground-handling walkouts at Tuscan airports.

What passengers can expect
This is a summary of public reports, not a decision on an individual booking.
- The airline should offer a reroute or a refund when it cancels the flight or the disruption makes the journey unusable.
- Care still applies while you are waiting: meals, refreshments, a means to communicate, and a hotel plus transfers if you need to stay overnight.
- Fixed compensation under EC 261/2004 or UK261 depends on the cause. Extraordinary circumstances, such as air traffic control restrictions or severe weather, usually mean the airline does not owe that fixed compensation. A strike by the airline's own staff is treated differently from an outside restriction.
- Check the latest status with the airline before you travel.
