Air France says that it has canceled about 20% of its flights due to a pilots' strike. The pilots are protesting a government plan that would require two days notice before a strike. The strike will last until Thursday, and the union says that they expect support to grow as the strike continues. The government says that the plan would help companies plan more effectively for strikes and reduce the number of canceled or disrupted flights.
