United adds automatic earlier-flight standby alerts to its mobile app during disruptions

Eligible customers rebooked after irregular operations can keep a confirmed itinerary while joining standby lists for up to three earlier United flights to the same destination

United’s new mobile app feature can monitor up to three eligible earlier flights for customers rebooked after a disruption and send a text when a seat becomes available.

(NEWS) CHICAGO, Illinois, United States, 2026-Sep-02 — /Travel PR News/ — United Airlines is giving disrupted passengers another way to recover their journey without repeatedly refreshing flight options or giving up a confirmed seat, adding an automated earlier-flight standby function to its mobile app.

The new feature is designed for eligible customers who have already been rebooked onto a later flight following a disruption. Through the United app, they can place themselves on standby for as many as three earlier United-operated flights to the same destination while retaining their existing confirmed reservation.

Rather than requiring travellers to keep checking whether seats have opened, United says its system will monitor the selected flights in the background and send a text message when space becomes available. The passenger can then decide whether to move to the earlier option, with the confirmed replacement itinerary remaining intact until that choice is made.

The airline is rolling out the functionality ahead of the U.S. Labor Day travel period from September 3 to 8, 2026. In its September 1 announcement, United said it expects more than 3.4 million customers to travel during the six-day holiday window, around 300,000 more than a year earlier.

For travellers, the practical benefit is most evident during irregular operations, when later rebooking options may be confirmed quickly but earlier seats can reappear as other passengers change plans. Allowing customers to remain protected on a confirmed flight while simultaneously monitoring multiple earlier departures reduces the trade-off between security and flexibility.

Jennifer Schwierzke, United’s vice president of Customer Operations, Strategy & Execution, said the airline is trying to make disrupted journeys easier to manage by shifting more of the availability monitoring into the background. United also said more than 85% of its customers use the airline’s mobile app on the day they travel, underscoring the role of digital self-service in its disruption strategy.

The standby function joins a broader collection of recovery tools already available through United’s digital channels. These include automatic flight rebooking, meal and hotel vouchers for eligible customers and checked-bag tracking, with the aim of reducing the need to queue for an airport agent when operations are under pressure.

United has also continued to expand the app beyond disruption handling. Recent additions cited by the airline include enrollment support for TSA PreCheck Touchless ID through Digital ID in Apple Wallet, inbound-aircraft status information, TSA security wait-time estimates at U.S. hub airports, turn-by-turn directions for connecting passengers and Apple Share Item Location integration for customers using AirTag or other Find My network accessories.

While United describes the new standby system as an industry first, the more important change for passengers is the combination of automation and choice: travellers can hold onto the certainty of a confirmed rebooking while the airline’s app watches for a faster way home.
