Changes can be made online, via the mobile app, or by contacting Delta's reservations center.
If the new flight is more expensive, the customer must pay the fare difference.
If the new flight is less expensive, the difference in fare will not be refunded.
If a passenger needs to change their flight within 72 hours of departure, they may be charged an additional fee.
