Kayak also offers tickets for international flights on many foreign airlines, such as Lufthansa, EVA Air, Singapore Airlines and Korean Air. Availability and prices vary based on travel dates and desired lengths of stay.
An independent subsidiary of the Priceline Group, Kayak provides a travel-search engine on its website and mobile app. The user enters his departure and arrival destinations and travel dates into a search field, and then filters his results by criteria such as nonstop, one-stop and multiple-stop flights. Then Kayak searches its database for available flights. The user also may request a search of other travel sites, such as Orbitz, Priceline, and Expedia if he wants to compare prices, departure and arrival times. When he finds the flight that best meets his needs, he clicks Select and Kayak redirects to the website of the designated airline or provider.
For travelers searching for discounted airfares, Kayak also provides a price-alert, which sends periodic email notifications about changes in airfares. Users must log in with a Kayak username and password or a Facebook or Google account to access this feature.Learn more about Geography
