Core Event: Nationwide Flight Delays and Cancellations
On Friday, October 16, 2026, a technical fault in the data transmission network that underpins Italy’s air traffic control (ATC) system forced ENAV to impose temporary capacity restrictions, leading to widespread flight delays and cancellations at major airports.
Background & Context: The Data Network’s Role in ATC
ENAV’s ATC services rely on a dedicated data transmission network to exchange real-time information between radar, flight-plan and communication systems. The fault, identified as a network problem rather than equipment failure, prompted ENAV to activate a secondary satellite link while the primary connection was repaired.
Timeline of the Disruption
- Overnight (Thursday–Friday) – ENAV detected anomalies in the data transmission network.
- 06:00 local time – Flow-management measures halved the volume of aircraft that could be handled.
- Around 10:00 GMT – Cirium recorded 192 flight cancellations and noted that only about 31 % of scheduled departures were on time nationwide.
- 13:25 GMT – ENAV announced full operational capacity had been restored.
- Later – Airport operators issued passenger advisories; a 24-hour cabin-crew strike at EasyJet was reported as an additional source of disruption.
Data & Statistics
- Cancellations: 192 flights (Cirium).
- On-time performance: 31 % of departures nationwide; 25 % at Milan Malpensa; 28 % at Rome Fiumicino.
- Capacity handling: At the peak, ENAV managed roughly half of normal traffic, later rising to 75 % via satellite backup before full restoration.
Official Statements & Responses
ENAV ruled out sabotage, stating its ATC equipment functioned normally and the issue lay in the data transmission network. It is working with telecommunications provider TIM to determine the root cause. Airport operators advised travelers to verify flight status directly with airlines.
On-the-Ground Reports
Passengers at Rome Fiumicino, Milan Malpensa, Milan Linate, and Naples Capodichino reported delays of up to 60 minutes and multiple cancellations, including flights to Riyadh, Tirana and Trieste. Staff urged travelers to check airline communications for updates.
Conflicting Reports & Gaps
- Restoration level: Reuters said ENAV restored full capacity by 13:25 GMT, while US News reported an initial 75 % restoration via satellite before full functionality.
- Cause investigation: ENAV identified a network issue but has not released detailed technical findings or a timeline for a formal investigation.
What’s Next
ENAV has not set a timeline for a post-incident review. Airport operators will continue monitoring the situation and advise passengers to stay in contact with airlines for the latest information.
