The airline launched daily flights to Charles de Gaulle in May. Initially a seasonal service, it was later extended to year-round.
From October 28, the newly deployed Embraer aircraft will extend capacity on the route by 336 seats a week, up 24%.
Benedicte Duval, general manager Air France KLM UK and Ireland, said: “We are delighted to be in a position to increase capacity by 24% on the Cork to Paris route just a few months after launching in the region.
“The positive performance to date is testament to the economic recovery in southern Ireland and the investment Air France-KLM is making in this region.
“The extra capacity will offer our Irish customers more choice and connectivity, further facilitating growth in both the inbound and outbound markets.”
Outbound flights will depart Charles de Gaulle at 1520 arriving Cork 1615; returns will depart Cork at 1655 arriving Paris 1945.
Return economy fares start from €129.
Niall MacCarthy, managing director Cork airport, added: “The deployment of a new Embraer E-190 aircraft, resulting in increased capacity on the Cork-Paris route this winter, is testament to Air France’s confidence in the route and the support it has enjoyed in the past six months.
“France is one of the leading markets for tourism to the island of Ireland. The expansion by Air France will make it even easier for French visitors to travel to the south of Ireland and explore all that the Wild Atlantic Way and Ireland’s Ancient East has to offer.
“It also benefits Irish passengers travelling to Paris and onwards across the globe via Air France’s hub at Paris-Charles de Gaulle.”
