Kayak is a travel search engine. Which means we search hundreds of travel sites from all over the world, provide the information to you in an easy-to-use display and send you directly to the source to make your purchase. More than any other travel site, we help you find the perfect flight, hotel, cruise, or rental car. After all, what good are 1000 options when you can't find the flight you want? Once you make your choice, we link to the travel sites to make your purchase. Kayak allows you to choose which site to purchase from– through an online travel agency or consolidator such as Orbitz or Airfare.com. Kayak's search engine can find all kinds of travel products– from flights and hotels to rental cars and cruises. Our fare alerts and fare history help travelers stay on top of ever-changing travel prices.

In short, you are in control of your travel choices. Since we search hundreds of travel websites (including online travel agency sites), you now have to search only one: Kayak.
