The carrier wants to get rid of 6,560 positions of the 41,000 at Air France, and 1,020 positions of the 2,420 at Hop!, according to a statement issued after meetings between managers and staff representatives.
"For 3 months, Air France's activity and turnover have plummeted 95%, and at the height of the crisis, the company lost 15 million euros a day," said the group, which anticipated a "very slow" recovery.
Air France said it wanted to begin a "transformation that rests mainly on changing the model of its domestic activity, reorganizing its support functions, and pursuing the reduction of its external and internal costs."
The planned job cuts amount to 16% of Air France's staff and 40% of those at Hop!
With the focus on short-haul flights, management is counting mainly on the non-replacement of retiring workers or voluntary departures and increasing geographic mobility.
However, unions warn that Air France may resort to layoffs for the first time, if not enough staff agree to leave or move to other locations.
'Crisis is brutal'
Shaken heavily by the coronavirus crisis, like the entire aviation sector, the Air France group launched a reconstruction plan aiming to reduce its loss-making French network by 40% through the end of 2021.
"The crisis is brutal and these measures are on an unprecedented scale," chief executive officer Anne Rigail conceded in a message to employees, a copy of which Agence France-Presse (AFP) obtained.
They also include, she said, "salary curbs with a freeze on general and individual increases (outside seniority and promotions) for all in 2021 and 2022," including executives of Air France.
The airline told AFP earlier this week that, "The lasting drop in activity and the economic context due to the COVID-19 crisis require the acceleration of Air France's transformation."
Air France-KLM posted a loss of 1.8 billion euros in the 1st quarter alone, and has warned it could be years before operations return to pre-coronavirus levels.
The group joins a long list of airlines that have announced job cuts in recent weeks.
