Radio frequency loss grounds flights in Greece, stranding thousands

Radio frequency disturbances caused a nationwide suspension of flights, grounding over 90 flights and stranding thousands, with partial service resuming by afternoon, Greek authorities said.

  • On January 04, 2026, airports in Greece suspended arrivals and departures after radio frequency disturbances halted national air traffic services, grounding flights nationwide.
  • Psarros indicated the problem appeared to be a collapse of central radio frequency systems at the Athens and Macedonia Area Control Centres, affecting all aircraft communications in Greek airspace.
  • Flight trackers recorded largely empty Greek airspace while more than 75 flights were delayed and flights were diverted to neighbouring countries, state broadcaster ERT reported.
  • At Athens' Eleftherios Venizelos International Airport, travellers were left stranded as terminals became crowded, while the Israel Airports Authority warned Greek airspace could remain closed until 16:00 local time.
  • Amid the outage, Psarros said controllers 'we haven't been informed about the cause of this problem... certainly the equipment we have is virtually ancient,' linking it to equipment concerns.
