Reviewers and users agree that Kayak.com is the best resource for finding the cheapest air, hotel, cruise and car rental prices. Booking sites search only their own databases, but Kayak.com includes more than 200 booking and service-provider websites, including some international ones. One interesting tool lets you see the best fares for similar routes searched by other Kayak.com visitors; you can also receive daily or weekly email alerts if prices change for designated routes and destinations. You can't book travel through Kayak.com, and occasionally the price for the travel you select may not be available when you go to purchase it at a booking or service provider's site. Kayak.com offers apps for the iPhone, Android and BlackBerry. If you want to track airfares after booking to receive a possible refund if the price drops, Yapta.com has the same search engine as Kayak.com and offers post-booking tracking.
Kayak.com receives no shortage of media attention. We found endorsements for Kayak.com at Travel and Leisure, PC World, WalletPop.com, Kiplinger.com, BudgetTravel.com, Time magazine and TriponaDeal.com.

7. Time magazine
Brad Tuttle and Erik Torkells say to search for flights at Kayak.com, rather than a booking site like Expedia.com, Orbitz.com or Travelocity.com. However, they also add that while Kayak.com is the best search site, even it misses some airlines and flights, so you should check other sites as well, and specific sites are named.

12. The Washington Post
Kayak.com earns a listing here as one of five best overall travel sites. Kayak.com is one of five sites listed in the all-around travel category. Michael Shapiro says you should not rely on one site for the best deal, but adds that Kayak.com's concept of searching lots of sites of once "sounds good, and it often is." This review, however, is rather outdated.
