Extensive travel disruption is expected due to a general strike in Greece today.
The 24-hour protest against planned new spending cuts of more than €11.5 billion will affect air services and ferries.
A three-hour walkout by air traffic controllers will disrupt flights around the country.
EasyJet has been forced to re-schedule 30 flights due to the industrial action by controllers from 10 am local time.
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.”
