Air France says it has canceled about 20 percent of its flights due to a strike by flight attendants.
The strike is affecting mostly short- and medium-haul flights out of French airports, but 10 long-haul flights were also canceled Saturday.
The airline said the situation at Paris' main airport, Charles de Gaulle, was largely normal, with most passengers on canceled flights rebooked on other airlines. At Paris' Orly airport, however, about 200 passengers were waiting to be rebooked.
The strike, in protest against cuts to cabin crews, comes during an extended school holiday and at the start of a long weekend in France. Tuesday is a public holiday and many here travel for the four-day weekend.
