A look at results from selected companies in the airlines industry:
Feb. 15: AMR Corp., the parent of American Airlines, lost $1.1 billion in the fourth quarter as it wrote down the value of planes and other property and paid more for jet fuel. The company, which filed for bankruptcy protection in November, said that the results compared with a loss of $97 million a year earlier, when AMR still hoped to avoid bankruptcy by cutting costs. AMR said it spent $394 million more on fuel in the latest quarter than it would have at last year's prices. For the full year, the company posted a net loss of $2 billion, compared with a loss of $471 million in 2010.
Feb. 16: Spirit Airlines said higher fares — combined with those fees passengers love to hate — helped its net income more than double in the last three months of the year. Spirit, which went public in May, sells relatively low-cost fares for the U.S., Latin America and the Caribbean. The Miramar, Fla., company said it earned $24 million in the fourth quarter compared with $9.5 million in the fourth quarter of 2010.
Feb. 16: SkyWest Inc., which operates regional flights for US Airways, United and Delta, reported an $18 million loss in the fourth-quarter due to aircraft maintenance issues and other unexpected costs. It booked charges including $15.6 million for additional maintenance as many of its planes came due for extensive maintenance checks and $8 million in additional crew costs. In the last three months of 2010, the St. George, Utah, company earned $37.2 million, or 67 cents per share.
