* US Airways Group Inc., the sixth-largest U.S. carrier, said that earnings per share in the year’s second half will be lower than analysts forecast on weaker revenue and higher costs for labor and fuel. The carrier was forecast to earn $1.66 a share in the third quarter and $1.31 in the fourth, or a combined $2.97, based on average estimates by First Call Corp. The company’s statement came in a letter to investors that was also disclosed in a Securities and Exchange Commission filing.
