Athens - Hundreds of workers with Greek state carrier Olympic Airlines blocked the main runway at Athens International Airport Tuesday over plans to privatise the airline.
The demonstrators, including pilots, air stewards and technicians, prevented planes from taking off and landing on the runway.
Airport officials said the protest forced air traffic controllers to divert planes to a second runway. The demonstration did not affect any flights, they added.
Tuesday's airport protest was the second in one week.
The European Commission last week approved a government plan to privatise the airline while ordering the current company to pay back more than 1 billion dollars in illegal state aid.
