Click the Flights link at the top of any page on Kayak.com. Enter departure and return information and the number of passengers traveling together. Click Search to see a list of available flights matching your search criteria.
The Kayak flight search page allows you to choose round-trip, one-way or multi-city options. The search fields adjust to match the flight type once you click the corresponding type. The one-way flight screen only displays the departure date, since you won't need a return flight. The multi-city page shows three lines, allowing you to list the segments of the trip with the option to add up to six more.
If you have flexibility in your travel plans, click the Show Flexible Dates link just below the Search button. Enter departure and return dates. Search for exact dates, weekends or three days before and after the dates entered. Get comparison rates from other travel websites by checking the boxes in front of the names.
The search results page lists the flights that fit your criteria with flight information, including price, time and layovers. The left side of the screen offers filtering options to find the best flights for your needs. Filtering options include the number of stops, airlines and the takeoff time.
