Japan Airlines Corp. is having a hard time getting its retirees to approve drastic cuts in pension benefits as it heads toward court-backed rehabilitation, sources close to the matter said Sunday.

The ailing carrier needs two-thirds approval and the working deadline is Tuesday.

Separately, the state-backed body in charge of turning around struggling JAL is also expected to urge the company to decline investment offers from America's two biggest carriers amid concern a capital tieup could complicate its rehabilitation plan.
