American Airlines said on September 29, 2004, it will begin testing in November the renting of portable entertainment systems, like the one seen in this handout photo, in a bid to increase revenue and provide a bit more service to customers traveling on the world's largest airline. The systems will rent on select U.S. flights for $10-$12 and come stocked with items such as movies, music videos and online news. NO SALES REUTERS/HO/American Airlines
