Air France says it expects to maintain more than 85 percent of its long-haul flights and 80 percent of European flights when pilots, cabin crew and other personnel begin a four-day walkout Monday to protest a government labor reform.The French airline did not say how many domestic flights it would have to cancel, and added that it may have to cancel some flights at the last minute. It is offering free rescheduling for passengers with tickets for travel Feb. 6-9.

Labor unions have called the strike to protest a bill in Parliament that would require air transport workers to give 48 hours’ notice before striking, as is already the case for French railway employees.Unions call the proposal an infringement of the right to strike.
