Japan Airlines Corp., seeking its fourth state bailout since 2001, rose the most in a week after Nikkei English News said the government may announce a restructuring plan as early as today.

The carrier gained as much as 6.3 percent, the most since Oct. 21, and was up 5.4 percent at 118 yen as of 9:47 a.m. in Tokyo trading.

Transport Minister Seiji Maehara may introduce legislation for a Japan Air turnaround plan that includes state-backed loans and pension cuts, Nikkei said, without saying where it got the information. The carrier, also known as JAL, is seeking government aid and debt forgiveness from lenders as it heads for its fourth loss in five years.

JAL is also considering selling a stake to AMR Corp.’s American Airlines or Delta Air Lines Inc. American, the world’s second-largest carrier, has proposed a deepening of ties with JAL as it seeks to keep the Tokyo-based airline in the Oneworld alliance, a person with knowledge of the plan said yesterday. Delta, the world’s biggest carrier, is a member of the rival Skyteam grouping.

Public broadcaster NHK also reported that JAL will seek support from the government-affiliated Enterprise Turnaround Initiative Corp. as early as today, without saying where it obtained the information.
