AFP - French flag-carrier Air France cancelled more than a third of its long-haul flights and a quarter of shorter journeys Thursday as a four-day strike by aviation workers entered its final day.

The strike by pilots, flight attendants and ground staff was costing Air France eight to 10 million euros ($11-$13 million) per day, the company said.

Air France said it was operating 65 percent of its long-haul flights and 75 percent of medium- and short-haul flights, including by regional subsidiaries.

About the same proportion of flights had been cancelled on the third day of the strike on Wednesday.
