Unions representing French aviation workers, including pilots, flight attendants and baggage handlers, voted Friday for strike action on February 6-9 that is expected to disrupt air travel.
The unions are protesting a draft law that will require individual aviation workers to give 48 hours notice before taking strike action.
The bill was approved by France's lower house last week and is being studied in the Senate.
It was unclear how much disruption the strike will cause as unions have not provided details about what form it will take, but union leaders have called for widespread action across the country.
Air France has already announced that passengers with tickets booked for February 6-9 can reschedule without charge.
