What Does KAYAK Actually Do?
KAYAK compares travel offers across airlines, hotels, rental cars, and agencies, then usually sends the traveler to a provider. Filters, flexible dates, alerts, Explore, and Trips support research.
KAYAK is not necessarily the seller or support desk. A low third-party fare may carry poor service or strict baggage rules, and price forecasts are estimates rather than guarantees.
