With more and more airlines offering in-flight Wi-Fi to passengers, there's little reason why you should be stuck with an internet-less phone or tablet on your flight. Now, thanks to a partnership with Routehappy, Google Flight Search lets you know which flights offer Wi-Fi and other amenities at a glance.

Routehappy is a service that lets you find the "happiest" flights — meaning those with the most amenities and the roomiest seats. Its data is already integrated with Google Flights — once you've selected a flight, you'll see how much legroom you'll get and whether it offers in-seat power or Wi-Fi.

"We know people are looking for more information about the flights they're taking before they buy, so Routehappy Happiness Factors is a great addition to Google Flights," said Gianni Marostica, Director of Business Development at Google's Travel division.

Google's flight search, which was updated in February, does not let you actually book flights. Instead, it scours Google's huge database to show you the cheapest tickets, both through booking companies and airlines directly.

It's not all about saving money, though; Google Flights tries to show you the best flights instead of the cheapest — those that offer the "best combination of price and convenience." The service also offers a semi-random destination for travelers who aren't sure where they want to go just yet.
