Orbitz has launched a new version of their app earlier this week that lets you book flights, hotel rooms, and car rentals in one go. Orbitz now has an advantage over other travel apps. Kayak sends users to browser screens within the app and Expedia requires users to enter data over and over. ?Mobile commerce is skyrocketing,? stated Orbitz VP of product strategy Chris Brown. ?People use mobile phones on the train and during such times when they can accomplish more than on a desktop.? In May 2012, about 6 million Orbitz users shopped on Orbitz through their mobile device. This is more than double the previous year.
