United Airlines is enhancing its iOS and Android mobile applications with a variety of new functionalities, such as projected security wait times to assist travelers in determining their arrival times at the airport. This initiative arises amid a partial government shutdown that has resulted in understaffed TSA checkpoints.

In the “Travel” section of the United app, passengers can now view security wait times for the airline’s U.S. hub airports located in Chicago, Denver, Houston, Los Angeles, New York/Newark, San Francisco, and Washington, D.C. Users will find estimated wait times for specific lanes, including standard security and TSA PreCheck, across terminals catering to United customers.

“We value the work and dedication of our TSA agents, and while many started receiving back pay earlier this week, the U.S. Department of Homeland Security shutdown persists, and travelers wish to stay updated on expected security wait times at our airports,” stated Jason Birnbaum, United’s chief information officer, in a press statement. “Our customers depend on our mobile app for all their travel requirements, and this latest feature helps them understand what to anticipate and plan their journey more effectively.”

The app is also introducing features intended for passengers with connecting flights. Travelers will now get personalized, turn-by-turn directions to their next gate, along with estimated walking durations, real-time status updates, and suggestions for longer layovers. It will also alert travelers if United can pause a plane for those with tight connections.

Additionally, the app will include automatic rebooking support. Rather than waiting in line to consult an agent or manually exploring alternatives, United’s self-service options will promptly offer travelers rebooking choices, complete with baggage-tracking information and meal and hotel vouchers if they qualify, in the event that a flight is delayed or canceled.

The app has also incorporated Apple’s “Share Item Location” feature for AirTag, enabling travelers who utilize an AirTag or other Find My network accessory to communicate their item’s location with United’s customer service team if their baggage is misplaced.

Users will also receive text alerts with real-time radar maps to inform them how severe weather in one part of the country can impact flights in another area.
