Northwest Airlines asks for bankruptcy extension
Northwest Airlines Corp. asked its bankruptcy judge to extend the period during which it alone can propose a reorganization plan.
A motion filed Friday in U.S. Bankruptcy Court in New York asked that the so-called exclusivity period be extended to June 29, 2007. It is due to expire March 16. Currently, only Northwest can propose a reorganization plan, which it did on Jan. 12. After the exclusivity period ends others, such as creditors, can propose their own plan for the company.
Northwest has said it intends to emerge from Chapter 11 by the end of the second quarter, which is June 30. It filed for bankruptcy protection on Sept. 14, 2005.
