Delta Air Lines announced that customers who need to change their flight on the day of departure can now stand by for an earlier, alternative flight without paying a fee. The new flight must depart the same day, and standby requests or a confirmed change must be made within 24 hours of departure. Customers can make their same-day travel change directly within the Fly Delta app or on delta.com. Sandeep Dube, senior vice president-pricing and revenue management, said flexibility has never been more important, “which is why we want to give our customers more choice and control over their travel plans than ever before.” He said that by enabling same-day travel changes directly on the Fly Delta app, customers will also save time rescheduling their plans while on the go, without waiting in line at the airport or calling reservations. Same-day changes are available for all domestic tickets except Basic Economy.
