A government-backed corporate turnaround body plans to ensure that Japan Airlines Corp. will have complete access to loans necessary to maintain key operations even if the cash-strapped carrier has to file for court-backed bankruptcy protection, sources said Wednesday.

Enterprise Turnaround Initiative Corp. of Japan will also seek to save mileage points JAL users have collected and will aim to keep JAL's shares listed to stem credit fears among clients and to control turmoil in equity markets.

Separately, other sources said Japan's top carrier is arranging to find a replacement for Chief Executive Officer Haruka Nishimatsu from outside its corporate group.
