I just flew to Las Vegas for my dad’s 88th birthday. My round trip, non-stop fare from Cleveland including all taxes, baggage, and everything else cost me $179!

hopperThat price wasn’t a lucky fluke. I used a new iPhone/iPad app called Hopper.

Hopper uses data and analysis from “billions” of flight prices in order to tell travelers when they should fly and buy tickets. The company claims that it’s able to save users as much as 40 percent on flights. From my experience, that’s being conservative.

The makers of Hopper noted that there’s no “best day” to book, but consumers often miss the chance to snag a lower fare because they’re only spot-checking for changes and decreases. With Hopper, the idea is that you can monitor a particular route continuously using its “Watch a Trip” feature, which gives you a better chance at catching a better fare. When the fare drops, Hopper can alert you via a push notification, which can also inform you if the price isn’t likely to fall further. It can notify you if fares are about to increase, as well.

Another feature, “When To Fly,” also helps travelers by visually color-coding dates so it’s easier to see when the best travel days are to save more money. The app helps you discover the cheaper airports, too.

For my friends with Android and Windows phones, the app isn’t available for you yet, BUT you can use Hopper from its website at http://www.hopper.com/.

For everyone else, download Hopper for free in the App Store from your phone.
