The Hopper app for iPhone can do the job that we’ve all come to expect—search for the best fares—but also can predict when those fares will go up or down. Promising “data-driven advice,” Hopper will look at your dates and destination, then suggest adjustments in departures, airlines, and airports that can save hundreds. Here’s the innovation—the app also will let you know if it’s the right time to buy. By analyzing massive amounts of travel news and price data, Hopper predicts if cheaper flights are just around the corner, or if the time to buy is now. Visit to learn more or download.
