France's air traffic authority has told airlines to cancel 20 per cent of flights because a number of airline employees and air traffic controllers have indicated that they will join the strike.
At Charles De Gaulle there will probably be delays but no cancellations, officials said.
Air France says it will maintain all its long-haul flights and all flights to Charles De Gaulle but only 80 percent of domestic flights and those to Orly.
There will also be disruption of Paris regional transport with half the trains between Paris and Charles De Gaulle airport cancelled.
Buses and trams are expected to run "more or less normally".
France's rail network suffered delays and cancellations on Tuesday because of a national rail strike.
