International Airlines Group’s long-haul low-cost airline Level makes its debut in Paris today with its first transatlantic flight.

The offshoot is to fly from the French capital’s Orly airport to Montreal from tonight with three flights a week costing from €99 one-way.

Level will also run four flights a week to Guadeloupe from Tuesday.

Two new Airbus A330-200s will be based at Orly, each with 293 economy and 21 premium economy seats.

A third widebody Airbus will be added next year “providing the opportunity to expand Level’s network further”.

The aircraft are equipped with the latest high speed Wi-Fi with prices starting at €8.99.

Another A330 will start long-haul services from Barcelona in September followed by a second next year, bringing the Spanish fleet up to four aircraft.

Level currently operates from Barcelona El Prat airport to Buenos Aires, San Francisco and Boston with a summer service to Los Angeles.

IAG chief executive Willie Walsh said: “We’re delighted to start flying from our second European city. Level is performing really well and ahead of our expectations in all markets.

“We will continue to invest in Level and are committed to accelerating its growth.

“Last week we launched its new short-haul operation in Austria which will fly from Vienna to 14 European destinations from July 17.

“Level is breaking the mould by providing consumers with more choice and amazing fares.”

Level’s Paris flights are operated by IAG’s French airline OpenSkies which has transitioned into Level.

Passengers are able to earn and redeem Avios, the loyalty currency for IAG’s airlines.

They can also use ‘Pair & Pay’ technology to browse and buy on board from their seats using personal devices.

The system allows passengers to connect mobile devices with their individual seatback screen to buy food, drinks, wi-fi packages, amenity kits, headphones and duty free items.
