What it does
KAYAK searches travel offers from airlines, hotels, rental companies and other booking sites. It presents booking-source labels so travellers can distinguish an airline offer from one supplied by a travel partner.
Pay attention to the seller as well as the departure time. KAYAK describes labels such as Book with Airline and Book with Partner, which help explain where an offer comes from. That is useful when similar-looking journeys appear through several providers.
Start with flights, stays or cars and use the same passenger and date details when comparing alternatives. The flight search also includes a bag selection, an important part of making a like-for-like comparison. KAYAK says that it does not sell or process reservations itself. Once you choose an offer, the booking provider’s process becomes central, so keep its name with your reservation details. The site also links to a flight tracker and planning resources for later stages of a trip.
