United Airlines says it's the first airline to offer passengers the Uber booking option on its app. For a limited time, the airline will reward United app users with 1,000 award miles in its MileagePlus program for using Uber, a statement says. TripAdvisor also announced that its app and mobile site would feature a "Ride there with Uber" button that estimates car fees for users browsing restaurants and entertainment sites and allow them to make a reservation too. "Instead of having to exit the TripAdvisor app, run the Uber app and enter the destination address, your Uber is on its way with just a tap, ready to whisk you off to the venue you were looking at," Jeff Holden, Uber's chief product officer, says in a statement. (The feature debuts in English and Italian on TripAdvisor, with more languages on the way.) Get the full story at the Los Angeles Times
