Tourists visiting Greece are braced for 48 hours of disruption as the country goes on general strike against unpopular austerity measures.
The walk-out is expected to affect dozens of international flights as air traffic controllers called two work stoppages: from 8am to noon on Tuesday and from 6pm to 10pm on Wednesday.
Those travelling by sea also faced disruption. At the main port of Piraeus, protesting dockworkers formed a blockade on Tuesday morning, leaving hundreds of tourists unable to board ferries to the Aegean islands.
All public transport was to halt for two days except the Athens subway which workers decided to keep running so that protesters could travel to anti-austerity rallies in the capital. But bus drivers said they would run a limited service for people participating in or attending the Special Olympics which Athens is hosting this year.
The strike also hampered public services, leaving hospitals operating at emergency staffing levels and closing schools, government offices and courts.
