(Dow Jones/AP) Washington, D.C. Northwest Airlines Corp., which says it's close to its goal of cutting annual labor costs by $1.4 billion, faces a new bill of more than $22 million from the lawyers and consultants who helped it achieve some of those cost reductions.The tab, revealed in documents filed with the U.S. Bankruptcy Court in Manhattan, covers work performed by 20 professional firms from February through May. The bill isn't comprehensive because court records typically don't cover all of the professional fees and expenses billed to a Chapter 11 company.Still, if the latest fee requests are approved, Northwest's Chapter 11 professionals will have cost it at least $45 million since the company began its bankruptcy reorganization last September. U.S. Bankruptcy Judge Allan Gropper is scheduled to consider the requests at a hearing Thursday.So far, the fee requests have aroused mainly technical obcharges for professional and paraprofessional services rendered in comparable nonbankruptcy-related matters," the law firm said.Adams, the U.S.
