It was another quarter in the red for American Airlines' parent company, AMR Corp.

The Fort Worth-based carrier posted a $97 million loss in the fourth quarter, compared to a $344 million loss in the same quarter in 2009. Revenues grew 10 percent to $5.58 billion in the quarter.

The fourth quarter loss was less than Wall Street analysts had predicted. Excluding a one-time charge of $28 million to write-down routes in Colombia, the company lost $69 million or 21 cents a share. Analysts had estimated a 33 cents a share loss for AMR this quarter.

For its fiscal year 2010, AMR had a loss of $471 million, a significant improvement over its $1.47 billion loss in fiscal year 2009.

AMR said it expects its capacity at American and its regional carrier, American eagle, to increase by 4.3 percent in 2011. The domestic mainline network will be up 1.0 percent while international routes will grow by 7.7 percent as American adds several new international flights including service from Los Angeles to Shanghai and New York's JFK airport to Tokyo-Haneda.
