Aviation authorities in France have told airlines at Paris Orly airport to cancel around 20 percent of their flights as air traffic controllers join a nationwide protest against labour reforms.
That means hundreds of flights will likely be cancelled at Orly airport, while aviation authorities from the DGAC are also warning of potential delays at the capital's main airport Charles de Gaulle.
“At Roissy Charles de Gaulle there will very likely be delays but not cancellations,” said a spokesman from the DGAC.
In a statement released to the press the authorities are also warning about disruptions to flights throughout the whole country.
Passengers are advised to check with their airlines first, before travelling to the airport.
The walk-out by air traffic controllers, as well as other airport staff, who are linked to the leftist CGT union is part of the latest nationwide day of action against the government's proposed labour reforms.
The raft of changes are basically aimed at making it easier for companies to hire and fire workers and make rules around working hours less rigid.
However opponents argue that workers will be left worse off and in a more precarious situation. They argue it shouldn't be workers who pay the price for high unemployment, but company chiefs and their profit margins.
The protests, which have often descended into violence, are being led by student and high school unions as well as leftist trade unions like the CGT and Force Ouvrier (FO).
Many of the workers at Orly airport are members of the CGT, hence the reason why Orly will be more hit than Charles de Gaulle airport, where the union has less of a presence.
The strikes is the latest industrial action that has led to transport chaos across the country.
On Tuesday scores of trains around the country were cancelled in the latest strike by SNCF rail workers.
And recent months have seen various strikes by air traffic controllers that have left hundreds of flights grounded and provoked thr wrath of Ryanair.
