Hopper is a useful app for watching flight deals, but they also want to be able to predict where you might want to travel next. Their new Flex Watch feature acts like a digital travel agent, making personalized recommendations for your trip to save you money.

Using an AI-driven recommendation algorithm, Flex Watch is able to craft you a vacation when you don’t have a set destination or specific dates in mind. It will alert you about flight deals based on your preferences and how flexible your possible travel dates, netting you an average savings of about 40%. Hopper’s launch announcement gives a brief example of how it might work:

“For example, a user watching flights to Maui might get a recommendation that a similar destination, Honolulu, is on sale for their dates for $200 less! We learned quickly that our users are very flexible if it means they’ll save money.”

First, you specify how flexible you are by inputting which month or months you’re potentially available to travel. Then you choose your ideal trip length (which should be at least eight days), and select which destinations you’re interested in traveling to. This can be very general, like “anywhere,” or you can narrow it down to continents, geographic regions, countries, states, or cities.

Once you have everything set, you can swipe through Flex Watch’s destination suggestions, complete with explanations as to why they’re affordable spots right now or will be in the future. If you swipe up, you’ll see all current deals for that destination, and see an overview of what months are the cheapest for traveling there. After that, all you have to do is wait. Hopper will continue to scan a real-time feed of 10 to 15 billion flight prices each day and notify you when it finds a flight deal within your parameters.

And over time, Hopper suggests their AI will learn and get smarter based on your likes and dislikes. If you want to try it out for yourself, the Flex Watch feature should be available on the iOS version of the Hopper app now, and will be coming to Android devices soon.
