If you’ve got American Airlines and have been frustrated by the lack of options to book short trips - listen up! AA is once again allowing customers to book so-called “short-hop” flights (example: Chicago to Atlanta or Dallas to Denver) for as little as 15,000 of your AAdvantage miles. You can begin booking these flights on AA.com for travel through September 1st, 2007, through February 20, 2008. Your flight must be on American Airlines, American Eagle or AmericanConnection carriers to use this deal.
