Greek air traffic controllers plan a series of walkouts this week in support of a nationwide public sector strike tomorrow (Wednesday).
Controllers plan stoppages today, tomorrow and Thursday alongside the general strike.
A four-hour walkout is planned on Wednesday, with no flights between 11am and 3pm local time.
Ferries will also be affected by a 48-hour strike today and tomorrow by members of the Hellenic Seamen’s Federation.
The action, which will affect public transport in Athens, is being taken in protest against Greek austerity measures.
The Foreign and Commonwealth Office updated its travel advice to say that public transport and other public services may be affected due to the 24-hour general strike by Greece’s two largest public and private labour unions, GSEE and ADEDY.
Update: Hellenic Seamen’s Federation announced a further 48-hour strike on May 18 and 19.
