Pro

👍 The United Airlines app streamlines booking and reservation management, letting users search flights, compare fares, select seats, and pay securely in minutes. Changes, cancellations and upgrades are handled easily, with stored traveler profiles and payment methods for faster checkout. It’s ideal for busy travelers who value speed and convenience.

👍 United’s mobile app delivers real-time flight status, gate and baggage updates, plus push notifications for delays, boarding and gate changes. Mobile check-in and digital boarding passes reduce wait times, while interactive airport maps and terminal directions help travelers navigate layovers quickly. Reliable alerts keep trips on track from departure to arrival.

👍 Integrated MileagePlus features and personalized offers reward frequent flyers with easy access to miles balances, upgrades and elite benefits. The app stores itineraries, supports multi-city bookings and tracks checked baggage so travelers can monitor progress. Customized travel recommendations and partner deals make planning smarter and maximize value for loyalty members.

Con

👎 The app can be unstable and sluggish for some users — slow load times, crashes during check-in, and delayed boarding pass generation. Frequent updates occasionally introduce new bugs, and heavy background battery and data use have been reported. These reliability issues create stress when managing last-minute travel on the mobile app.

👎 Navigation and feature discoverability can be confusing. Seat selection, change fees, and upgrade options are sometimes buried under multiple screens, and multi-city or complex itineraries are awkward to manage. Inconsistent labeling between platforms and unclear fee disclosures make it easy to miss important options or incur unexpected charges during booking.

👎 In-app customer support and booking modification tools are limited. Requesting refunds, rebooking irregular itineraries, or resolving award-ticket issues often requires calling or visiting the website. Push notifications and boarding passes can fail to sync across devices, leaving travelers without up-to-date travel alerts or digital boarding credentials when they need them.
