NEW YORK ( TheStreet) -- American Airlines ( AMR) said adjustments to its late fall and winter schedule will result in a 3% decline to its mainline capacity in the fourth quarter. The airline, in a statement, said it also plans to retire up to 11 Boeing ( BA) 757 aircraft in 2012. American said its advance bookings were "generally in line with last year," but it is taking the steps "in light of the uncertain economic environment, ongoing high fuel costs and to ensure" it runs a reliable schedule. With the latest moves to reduce capacity as fuel prices have risen, American said its full-year capacity for mainline will be up about 0.4% from last year, while consolidated capacity will be up about 1.2%. This is a roughly 3% reduction in the company's capacity expectations versus guidance the airline gave in January. -- Written by Joseph Woelfel >To contact the writer of this article, click here: Joseph Woelfel >To submit a news tip, send an email to: firstname.lastname@example.org.
