Malfunction in the Athens FIR System Paralyzes Air Traffic
A serious operational crisis occurred today in Greek airspace. Due to a large-scale technical malfunction in the Athens Flight Information Region (FIR) system, landings and take-offs at all airports across the country were temporarily suspended.
While the malfunction originated from the Athens-based system, which plays a key role in Greece’s air traffic management, its impact spread nationwide.

All Airports Affected, Including Athens Eleftherios Venizelos
Flight operations were suspended at all airports in Greece, including Athens Eleftherios Venizelos Airport, the country’s busiest airport. The technical issue directly affected:
- Domestic flights,
- International services,
- Transit operations.
This situation led to prolonged delays and passenger congestion at airports.
Civil Aviation Authority: Work Ongoing
In a statement issued by the Hellenic Civil Aviation Authority, it was confirmed that the issue was caused by a technical malfunction in the Athens FIR system. Officials stated that technical teams are continuing their efforts to resolve the problem, while no clear timeline was provided regarding when flights will return to normal.
Uncertainty in Flights Continues
The complete suspension of air traffic also affected many foreign airlines using Greek airspace, leading to knock-on disruptions in flight planning across the region. Further updates on the course of the crisis are expected.
