Since last May, users of Amazon's intelligent personal assistant, Alexa, have been able to realize their idle travel daydreams by searching for flights, hotels, and rentals cars through Kayak by simply speaking out loud to the talkative, robot cylinder in their living rooms. Now, the partnership has reached new heights, adding the ability to book a hotel room using nothing but your voice and a functioning Amazon Echo.

As Matthias Keller, Kayak's chief scientist tells Condé Nast Traveler, while the prior functionality left users essentially anonymous, the new ability to link your Alexa and Kayak accounts means "Alexa knows who you are, when your next trip is, or what time your flight is," and stores all the information in your Kayak account—credit cards and reward memberships, for example—so that you can simply tell Alexa to book your hotel and go on with your day.

The service works in two ways: If you're traveling, but haven't booked accommodation, you can tell Alexa your destination and dates and it'll list options out loud, including room type and general location. When you hear something you like, you ask Alexa to book, and confirmation will appear in your inbox or in your Kayak Trips account. But the real utility is for the frequent return visitor—that person who goes to the same city again and again and wants to stay in the same place. In that instance, just ask, for example, "How much is a room at the Omni Parker House?" and a few commands later, you'll be ready to tell your little helpful robot to book it for you.

While you can book hotels today, flights aren't quite there yet for Alexa. As Keller, explains, flights entail "more regulatory requirements, disclaimers that need to be displayed, security issues, and restrictions around payment methods." That doesn't preclude them from the future, though. "We hope that with hotel booking we can make that first big shift to becoming transactional on voice at all," Keller says.

Flights, car rentals, and integration with the new Echo Show (which includes a screen that would add the vital visual component to the booking process) are all next-up on the docket.

Of course, Kayak isn't the only travel service toying with artificial intelligence as a travel planning tool: Booking.com offers a digital travel assistant that will plan your Paris trip for you, and apps like Lola are using A.I. to create a digital, 21st-century travel agent. But Kayak's latest offering shows booking is moving toward a future where you'll use only speech commands. Keller doesn't shy away from dreaming big, either.

"Everything we have available right now is still very, very early—they've only been around for a year or two," says Keller. "This is just the beginning right now—in a few years, it’s all going to be much more seamless. We're moving closer and closer to an all-knowing travel assistant."
