The Next Generation Air Transportation System, known as NextGen, could revolutionize the skies by making air travel safer, lowering airplanes' carbon footprints, saving fuel and reducing flight delays. "This will fundamentally change how people fly," said Michael Huerta, Federal Aviation Administration's deputy administrator. However, NextGen depends on the willingness of the government and airlines to pay for it. "It's difficult to make that case" for airlines to invest in NextGen until they know they can receive a return on investment, said Steve Lott of the Air Transport Association.
