United's App Now Lets You Jump to an Earlier Flight and See TSA Wait Times Before You Leave Home

How the new standby feature works

The headline feature lets a customer who has already been rebooked — say, after a cancellation or missed connection — ask the app to monitor up to three earlier flights heading to the same destination. If a seat opens up on one of those earlier flights, the app sends a text alert. Critically, United says customers keep their original confirmed reservation the entire time they're on the standby list; nothing is given up by trying for an earlier departure, and the customer only switches once a seat is confirmed available.

United described this as "another first" for its app, framing it as an evolution of standby processes that have traditionally required a customer to physically visit a gate agent, add their name to a paper or kiosk-based list, and wait to hear a name called. Automating that process removes a layer of guesswork and gate-side queuing, particularly valuable during irregular operations when large numbers of passengers are simultaneously trying to rebook.

"This feature reflects our commitment to making travel more seamless and less stressful for our customers," said Jennifer Schwierzke, United's vice president of customer operations, in the carrier's announcement.

TSA wait times, before you've left for the airport

United's app-based visibility into security-checkpoint congestion is not brand new — the carrier introduced a TSA wait-time tracker earlier in 2026, initially covering seven of its hub airports: Chicago, Denver, Houston, Los Angeles, New York/Newark, San Francisco, and Washington, D.C. What the September 1 update did was fold that capability into the same wave of self-service features headed into Labor Day, alongside references from United describing itself as a first mover among major U.S. carriers on real-time checkpoint data. The tool shows estimated wait times broken out by lane, including standard security and TSA PreCheck, letting travelers judge whether a 60-minute cushion before boarding is generous or dangerously tight at a given terminal and time of day.

The app also now shows customers where their incoming aircraft currently is, displayed directly on the flight status page — a feature meant to give early warning of the kind of downstream delay that occurs when the plane scheduled to operate a flight is itself running late arriving from a previous route segment. Knowing that the inbound aircraft hasn't yet left its previous airport, for instance, can help a traveler recalibrate expectations, or even take advantage of the new standby tool to jump to a different departure entirely.

Other carriers have experimented with similar checkpoint-visibility tools, though industry reporting has noted that adoption has been uneven across the industry, partly due to limitations in how consistently TSA wait-time data can be shared with individual airlines' systems across every airport. United's approach has leaned on early and repeated public promotion of the feature as a differentiator, including through prior-year press releases that predate the September Labor Day bundle.

Bag tracking gets a real assist from Apple's ecosystem

The update also expands United's baggage-tracking capability by integrating with Apple's Share Item Location feature. Customers who travel with an AirTag or another Find My-compatible accessory tucked into checked luggage can now share that tracker's location directly with United customer service through the app, giving support agents a live data point to work from if a bag is delayed, misrouted, or goes missing.

This kind of tracker-sharing integration reflects a broader shift across the industry: airlines have increasingly leaned on passenger-owned Bluetooth trackers, rather than solely their own internal handling-scan systems, to locate bags that fall out of the normal tracking chain. Multiple carriers have rolled out similar AirTag- or Find My-linked support tools over the past two years as those consumer trackers have become common in checked luggage, and industry data cited in aviation trade coverage has pointed to steep reductions in permanently lost bags tied to that kind of tracker-sharing capability, though such figures vary by source and reporting period.

United separately operates a standalone bag-tracking tool at united.com that shows customers a package-delivery-style view of their checked bag's status through the journey; the AirTag-sharing feature announced September 1 builds an additional, passenger-supplied data source on top of that existing system.

Why the timing matters

Airlines have increasingly used major holiday travel peaks — Thanksgiving, the December holidays, and Labor Day among them — as launch windows for consumer-facing technology, betting that a spike in first-time or infrequent flyers using the app creates an opportunity to showcase new self-service tools when patience for waiting in physical lines is thinnest. United's framing of the update explicitly ties it to Labor Day volume, positioning digital self-service as a release valve for the kind of congestion and irregular-operations stress that high-volume weekends routinely produce industry-wide.

It also reflects a broader trend of airlines competing on app-based customer experience as much as on network or fare. Rival carriers have made parallel moves in recent months, including their own bag-tracking upgrades and mobile rebooking tools, as digital self-service becomes a competitive differentiator alongside traditional levers like route networks, loyalty program value, and cabin product.

Where United's app fits in a crowded self-service race

United is far from alone in racing to add self-service depth to its app. American Airlines has separately deployed upgraded self-service kiosks intended to reduce congestion during peak travel windows, paired with pre-purchased checked-baggage options designed to speed check-in for travelers who complete that step before arriving at the airport. Industry-wide, digital tools have become one of the more visible fronts of airline competition precisely because they are comparatively cheap and fast to ship relative to network expansion or new aircraft orders, and because a meaningful share of the flying public — industry estimates have put real-time-update app usage at roughly a third of passengers or more — now expects to manage disruptions from a phone screen rather than a help desk line.

That competitive backdrop makes United's decision to bundle four features into one release, rather than staggering them, notable. It concentrates marketing attention around a single moment — Labor Day — when the airline's own numbers suggest an unusually large one-time audience of travelers, including less-frequent flyers who may be opening the United app for the first time in months, will be exposed to the update simultaneously.

What this doesn't change

None of the four features announced alter United's underlying fare rules, change boarding priority, or affect loyalty program status or elite qualification — they are purely operational and informational tools layered onto the existing app experience. The standby feature, in particular, does not guarantee a seat on an earlier flight; it simply automates the process of monitoring and requesting one, subject to the same availability constraints that have always governed standby lists. A customer who doesn't get a seat on an earlier flight keeps their original confirmed booking exactly as before.

United has not indicated whether any of the four features will expand internationally or to smaller stations beyond its primary hub airports, where the TSA wait-time tool in particular appears to be initially concentrated. NewsFellow will note further rollout details if the airline provides them.
