Flights to and from Greece were facing severe disruption this morning due to a general strike against the country’s latest austerity measures.
Both public and private-sector unions called a general strike and protests for today (Thursday).
Disruption to flights throughout Greece included the grounding of services by Olympic Air and Aegean.
The four-hour work stoppage from 0700 GMT by air traffic controllers will also affect other airlines including those on international routes.
Ports, trains halted and urban transport in Athens is being affected due to the protest action which is also shutting banks, post offices and public services.
The strike is the sixth this year against a broad austerity policy imposed by the Greek government as it attempts to handle a debt crisis that pushed the country to the brink of insolvency in May.
