The impact was felt beyond Greece. An Israeli Airports Authority spokesperson said Greek airspace was expected to remain closed until at least 4.00 pm local time, warning passengers to brace for delays to both inbound and outbound flights.
Local media and aviation watchers reported widespread disruption. Greek City Times said on social media that no take-offs were possible nationwide due to the radio frequency failure, with massive queues forming at airports and passengers left stranded. While some arrivals were reportedly landing manually where feasible, many flights faced diversions or long delays.
“All Greek airports are affected, with the Athens FIR effectively closed,” the outlet said, adding that the Civil Aviation Authority was working to resolve the issue but had not provided an estimated time for normal operations to resume.
Airlines issued alerts to passengers, warning of significant delays and cancellations as authorities scrambled to restore systems and assess the full extent of the disruption.
