Best Travel Websites
Search for Flights: Kayak.com
Click Factor: Unlike many booking sites, which often list fares that are no longer available, Kayak searches 200 sources in real time so you'll find actual airfares (including all fees and taxes). The variety of customizable filters—airlines and carriers to frequent-flier consortia and arrival times—is unrivaled. You can also set up a daily fare alert and wait for the price to go down. New this year: the Explore feature, which offers a world-map view of fares, makes it easy to pick a destination.
Drawbacks: It isn’t always easy to find a range of fares, since Kayak only spits out what's available in real time. Also, discount carriers such as Southwest Airlines and easyJet aren’t always included as a rule.
T+L Tip: Book your flight through the airline’s site if Kayak offers you that option—it’ll save you a lot of hassle should you need help from the airline en route.
