US Airways Group
US Airways believes securing regulatory approval for its proposed deal would remove one key element of uncertainty from the picture, bolstering its case as AMR's creditors compare the merits of a merger with the carrier's standalone restructuring plan, the people said.
A regulatory filing now - as opposed to after reaching a deal - also reflects the fifth-largest U.S. carrier's desire to merge with AMR while the No. 3 U.S. carrier is still in bankruptcy.
Under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act, companies must not complete a merger until the U.S. Federal Trade Commission and Department of Justice determine that the transaction will not hurt competition.
Representatives for US Airways declined to comment. AMR said it did not have an immediate comment.
