In this photo Tuesday, Dec. 10, 2013, photo, the interior of an new jet plane is displayed at the American Airlines operations center in Grapevine, Texas. Airlines are on the largest jet buying spree in the history of aviation, ordering more than 8,200 new planes with the old planes bing sent to the desert where the dry air prevents the aluminum airframe from corroding and spare parts can be harvested or the old jets get chopped up for scrap metal.
