PARIS — Air France plans to cancel an unspecified number of flights as the result of possible national strike action planned on May 3-30 by pilots union SNPL, the airline said on Tuesday.

"This strike action is unusual both for its significance, lasting nearly a month, as well as for its methods which will penalize Air France flights at two peak times of day," the airline, part of Air France-KLM, said in a statement. France's largest pilots union is calling for strikes for two hours in the morning and three hours in the afternoon and most of the affected flights will be cancelled, Air France said in a statement.
