A four-hour general strike is being held across Italy on Friday (25 November) and is expected to affect air transport.
Air traffic controllers are among those stopping work between 1200 and 1600 local time.
State-controlled airline Alitalia said that it planned to cancel a total of 230 flights, including 105 national flights and 125 international services.
Other airlines were also expected to cancel flights because of the strike.
The action, which was initiated in protest against the government's 2006 budget, also includes hospital staff, teachers, postal workers and road sweepers, reported Reuters.
