In new plans outlined to the airline's works council, the French unit of Air France-KLM (>> Air France-KLM) targeted growth in its long-haul network from 2017, they said.
The measures are conditional on greater productivity efforts from pilots and cabin crew, they added.
Net investments would exceed 1 billion euros by 2020.
Air France said it had no immediate comment.
The airline said last week it would post a 2015 operating profit for the first time since 2008.
