PARIS, France -- Unions representing Air France pilots have threatened to disrupt May Day holiday travel this week to back demands for higher salaries.
A four-day strike is set to start on Thursday and will run until Sunday, when residents go to the polls to elect a new president.
An Air France spokesman said it was unclear how many flights would be affected by the planned strike.
The unions -- the National Union of Airline Pilots, Alter and SPAF -- are not happy with an agreement signed in December by Air France and three other pilots' unions, which called for an overall salary increase of 4 percent.
In a statement, the union said the strike had been called in response to "the intransigence of the Air France management toward some of our demands."
Talks were continuing on Monday between the airline and the unions in a bid to resolve the dispute.
