Kayak.com is he first travel site to be named after an Inuit boat (Igloo.com -- eat your heart out!). Kayak are not a travel agency and, unlike other travel sites, they don't sell anything. Which means they don't charge a commission on your trip.

Their handy, intuitive and fun tools search hundreds of websites to help you find the right flight, hotel and rental car for the perfect trip. Not to mention at the best price.
