Japan Airlines Corp. will cut 4,300 jobs over three years starting in April to help return to profitability, the airline announced Tuesday.

JAL plans to cut 700 of its 53,100 workers, mainly ground staff, through an early retirement program, and the rest by attrition.

The struggling carrier's medium-term restructuring plan also includes restructuring its domestic and international flight services, and selling some assets and shareholdings to boost earnings.
