Japan Airlines Corp., undergoing government-backed corporate rehabilitation, will seek to go public again by the end of 2012 under the recovery plan it must submit to the Tokyo District Court by Aug. 31, sources said Friday.

The plan also says JAL will cut its workforce by 37 percent by the end of fiscal 2014, compared with the end of fiscal 2008.

Through the public offering of its shares, JAL aims to repay ¥350 billion worth of capital that its rehabilitation administrator, Enterprise Turnaround Initiative Corp. of Japan, will inject into the airline, the sources said.
