United Airlines has introduced an updated version of its smartphone app. Version 3.0 of the app features a completely redesigned home page and adds an inbox, which stores travel messages such as boarding notifications and flight status changes, as well as a My Profile section that includes MileagePlus frequent-flyer program account information and United Club lounge passes. A key feature of the redesigned home screen is that it begins to update 48 hours before a flight. It continues to update with relevant information until arrival at the final destination. For connecting flights, for example, it will provide access to airport maps so a passenger can quickly locate the connecting flight’s gate. Other features include indoor airport maps and the ability to watch movies and television programs on select flights.
