The SNCTA union reportedly called the 2-day strike in a dispute over working conditions.
Following the French air traffic strike, hundreds of flights to and from France have been cancelled.
BBC reports that the SNCTA union called the 2-day strike in a dispute over working conditions.
According to France's civil aviation agency, part of the dispute involves plans to raise the retirement age for controllers from 57 to 59 years.
Short-haul flights have reportedly been the worst affected but France's largest airline, Air France, said long-haul flights were still operating.
The airline added that 60% of medium-haul flights from and to Paris' main airport, Charles de Gaulle, would still operate, but that it would ground 2 out of 3 flights at Paris' second-largest airport, Orly.
Further strikes are also planned for 16th to 18th April and 29th April to 2nd May.
