A three-hour walkout by air traffic controllers will disrupt flights around the country, with controllers leaving their posts from 10:00 local time.
easyJet has been forced to re-schedule 30 flights.
In a statement the airline said: “The industrial action is also likely to affect public transport around Greece so we strongly recommend that customers allow extra time getting to and from airports.”
Trade unions called workers out this morning for the first time since the conservative-led coalition government came to power.
