To find flights using Kayak, visit Kayak.com, select Flights from the tool bar on the home page, and enter your departure and destination airports into the search box, along with dates. Click Search to view a list of flights available for your chosen route.
The search box also offers a range of options to increase the choice of available flights. For example, check the Include Nearby box to include flights that use alternative airports. Additionally, if you have flexible travel dates, select the Plus or Minus Three Days option above the dates in the search box to view a range of flights on either side of your chosen dates. If you are restricted to flying on the weekend, select Weekends.
The search reveals a list of available flights sorted by price, with the cheapest flight first. Refine the search by selecting options from the bar on the left, including the number of stops, times of flights, airports, airlines and cabins. Kayak also provides links to other travel sites, such as Orbitz.com and Priceline.com. Click Compare beside each of the sites listed to the right of the screen to view flights on your chosen route and date, along with your chosen price.
