A group of Delta Air Lines Inc. unsecured creditors have banded together in an effort to make sure their interests are represented as the carrier considers a hostile bid by US Airways Group Inc.

The creditors, including Deutsche Bank Securities Inc., Lehman Brothers Inc., GoldenTree Asset Management, Marathon Asset Management and five others, announced the formation of an unofficial committee in a filing Thursday with the U.S. Bankruptcy Court for the Southern District of New York. A Paul, Weiss, Rifkind, Wharton & Garrison team including Alan W. Kornberg, Andrew N. Rosenberg and Brian S. Hermann is representing the group.
