United Airlines has introduced rebooking functionality in its app for customers who are placed on a later flight after a travel disruption, the carrier announced Tuesday.
Once rebooked, travelers can select to stand by for up to three flights that depart earlier than their new flight. United automatically will monitor availability and send a text notification when a seat becomes available, thereby eliminating the need to "repeatedly check the app to see if seats open up on earlier flights," according to the carrier.
A customer who receives a text that a seat is available on an earlier flight can keep the existing confirmed reservation until deciding whether to switch flights, according to United.
