Next time you book a flight, consider switching to an e-ticket. This simple swap can save you time and money, and help us save nearly 50,000 trees per year, according to the Air Transport Association. These digital tickets are impossible to lose (barring computer problems) and much easier to change, giving passengers greater flexibility.
P.S. e-tickets are not limited to airlines. Look for an e-ticket at the next concert or movie you go to.
