International Airlines Group will launch flights to Montreal, New York, Guadeloupe and Martinique from Paris Orly from July 2018 via Level - its low cost long-haul airline brand.
Level will base two Airbus A330-200 aircraft at Orly, each with 293 economy and 21 premium economy seats.
Checked luggage (plus a free cabin bag), meals, seat selection and the latest movie releases will be complimentary for customers flying in premium economy.
Those travelling in economy can chose what they want to buy based on a menu of choices.
Next generation in-flight technology will be available for all customers with a wide range of onboard entertainment options.
Customers can also earn and redeem Avios, IAG airlines’ loyalty currency, giving them the opportunity to fly to 380 destinations across the group’s network.
Level’s Paris flights will be operated by staff who currently work for IAG’s French airline OpenSkies which is based at the airport.
The OpenSkies brand will cease to operate at the end of next summer and all its staff will operate Level flights.
Willie Walsh, IAG chief executive, said: “Level’s Barcelona operation has been an incredible success.
“Customers love it and Level will be profitable this year.
“Barcelona was always a first step and today we’re delighted to launch flights from our second European city with four exciting new routes from Paris.
Tickets go on sale today.
Walsh added: “Like Barcelona, Orly is a Vueling hub which means that customers will be able to fly there from other parts of Europe to connect onto Level.
“We will also benefit from the local experience and knowledge of the OpenSkies team.”
Flights from Orly to New York will continue to operate under the OpenSkies brand until the end of summer 2018.
In Barcelona, Level will launch a new route to Boston on March 28th, 2018.
Flights will operate up to three times each week for the summer season.
A third A330-200 aircraft will be added to the Barcelona fleet later in the summer providing the opportunity to expand its network further.
Level currently flies from Barcelona to Buenos Aires, San Francisco (Oakland) and Punta Cana with a summer service to Los Angeles.
