Due to the participation of the Hellenic Air Traffic Controllers Association (HACA) in the 24-hour general strike announced by ADEDY on Wednesday 9 April 2025, from 00:00 to 23:59 local time, Aegean and Olympic Air inform the travelling public that they will make cancellations and modifications of all scheduled flights of the domestic and international network.

Travelers at Greek airports are facing problems in flights and baggage collection, which however do not resemble the chaos of European airports. 80% of delays today are caused by problems at European airports. About 600-1,000 pieces of baggage from flights that have already arrived, find their way to "Eleftherios Venizelos" airport every day, with management having installed a temporary logistics system to deal with this phenomenon.

Athens buses, trolleys as well as the metro and tram services have come to a complete halt on Tuesday due to the 24-hour strike called by the Civil Servants’ Confederation (ADEDY) against the government’s social security bill causing massive traffic jams across the Greek capital.
