I don’t know any more but am posting this from Greek City Times in case anyone is affected. I hope not
🚨 UPDATE: Athens Airport in Total Chaos – Security Check-In Closed Since 9 AM! 🚫✈️
Due to the ongoing radio frequency failure in Greek airspace (started early January 4, 2026), NO takeoffs possible nationwide.
Security check-in & departures halted at Athens International since ~9 AM
Massive queues building up, passengers stranded
Arrivals landing manually where possible, but many diversions/delays
All Greek airports affected – FIR Athens effectively closed
Civil Aviation Authority rushing fixes, but no ETA yet. Airlines issuing alerts – expect huge delays/cancellations today!
If you're at ATH or flying to/from Greece: Contact your airline NOW & check official updates.
Stay safe, travelers! 🙏
