United Airlines has revamped its iPhone, Android and BlackBerry 10 apps. The new versions include a streamlined user interface, along with a new feature, also available on Windows Phone 8, which will enable customers to manage their travel in real-time during what United calls “irregular flight operations”.

This will offer United mobile app users who experience flight delays or cancellations the option to keep their existing itinerary or, where available, the ability to change to a new itinerary. Customers whose flights are affected can use the app to accept new flights that United has automatically confirmed or search for alternate routes, airports and dates of travel.

“United continues to invest in mobile technology that improves the travel experience for our customers,” said Scott Wilson, Uniteds vice president of merchandising and ecommerce. “The new features and updated look of these apps give travellers increased convenience, flexibility and control.”

Wilson added that United would continue to invest in building mobile tools for its customers and said the airline would make mobile boarding pass scanning available at all of the more than 220 domestic airports it serves by the autumn. United was the first US airline to introduce mobile boarding passes in 2007, and is the first mainline carrier to announce plans to make the service available at all of the domestic airports it serves. United also offers mobile boarding passes at over 40 international locations.
