Staff and management at the French carrier have been locked in a dispute over pay since February.
Unions say workers deserve to benefit from years of belt-tightening that have returned the carrier to operating profitability, after seeing their wages effectively frozen since 2011.
Management says it cannot afford their demands of a 5.1 percent increase this year, saying it would undo the benefits of the restructuring efforts.
It is offering an increase of two percent for 2018, with another five percent staggered between 2019 and 2021.
Janaillac said he would circumvent the unions to put the proposals directly to staff in an online ballot.
“I will assume all the consequences of the result of this consultation,” he said.
“My future is nothing compared to what is at stake for the future of Air France.”
The strikes have chiefly affected short-haul flights.
The airline says the dispute has set it back by 220 million euros ($272 million).
