Before booking any kind of travel, I always start in the exact same place: Kayak.

The travel site has been my go-to for years, helping me book everything from business trips to vacations to quick weekend getaways.

But as time goes on, I've started wondering: Am I finding the best flights? Is there an easier-to-use site out there?

I turned to Google Flights to test whether Kayak should still be my top choice for booking travel. I use Google services almost everywhere else in my life — Maps, Gmail, Drive, Photos, Google Assistant, the list goes on — and I figured that if anyone could topple Kayak, it would be Google.

The services have a lot of features in common, the main one being that they both aggregate flights from major airlines and both take you off their sites to actually book your trip. But I was curious which had more standout features — and, of course, which could find me cheaper flights.

Here's how Kayak and Google Flights compare.
