Air France said on Monday that Joon would start off by flying to six destinations.

Starting from December 1, Joon will fly to four cities in Europe - Barcelona, Berlin, Lisbon and Porto. It will then fly to Fortaleza in Brazil and the Seychelles in summer 2018.

Joon, which is targeting the 'Millennials' generation, will be run by Jean-Michel Mathieu, who has been involved with the project since the start and has held various positions in sales, digital and revenue management within the Air France-KLM group.

Air France wants to bring down costs in order to compete better against Gulf carriers on long-haul routes, and against budget carriers on short-haul routes.
