The latest brand of the Dubreuil group, which also owns Air Caraibes, aims to start the long-haul services on Sept. 15, initially linking Paris with Punta Cana in the Dominican Republic, followed in June 2017 by services to Reunion Island and Mauritius.

"We will see if it works. We've given ourselves two years," Marc Rochet said. "If it doesn't work, we'll have to adapt."

Rochet did not elaborate on how it might adapt if the carrier fails to become profitable within that deadline.

No airline has yet proved a major success with low-cost long-haul travel between Europe and North America, though companies such as Wow Air, Norwegian and Lufthansa's Eurowings are all active in the market.

French Blue is due to take delivery of a 378-seat Airbus A330-300 jet at the end of June, with another A330 and two A350-900s scheduled for delivery in 2017 and 2018.

The airline plans to offer three types of fare, the cheapest of which will not include hold baggage, meals or choice of seat. It will also charge passengers to use on-board Wi-Fi services.
