AMR Corp., the parent company of American Airlines, reported a fourth-quarter profit yesterday following a year-earlier loss and said cost-cutting measures undertaken during restructuring would buoy earnings in future, Reuters reported yesterday. The carrier, which is weighing a merger with US Airways Group against exiting chapter 11 as a standalone company, said 2012 revenue grew 3.7 percent to $24.9 billion, its highest annual revenue ever. Net income was $262 million compared with a loss of $1.1 billion a year earlier.
