ANA Holdings Inc., parent of All Nippon Airways Co., said Monday it has notified bankrupt Skymark Airlines Inc. of its plan to take part in the struggling airline's restructuring.

Its support may include a capital tie-up, joint purchase of jet fuel and code-sharing, ANA Holdings said.

Japan Airlines Co., the other major Japanese carrier, has said it will not apply to be a sponsor for Skymark.

Monday is the deadline set for airline companies to submit sponsorship plans.

From other industries, Tokyo-based investment fund Integral Corp. has decided to extend a ¥9 billion loan. About 20 other companies had applied for sponsorship by last Thursday, including leasing firm Orix Corp., Shinsei Bank and Daiwa Securities Group Inc. as well as H.I.S. Co., a major travel agency involved in creating Skymark.

The troubled airline will examine each presented restructuring plan and draw up its final list of sponsors by the end of the month.

Skymark, which filed for court protection last month, will submit a rehabilitation plan to the court by May 29.

It faces a maze of issues, including dealing with European aircraft-maker Airbus S.A.S. over a penalty charge for breach of contract.
