Kiwi.com operates as a flight search engine specializing in 'virtual interlining,' a proprietary algorithm that combines flights from non-partner airlines to construct unique, often cheaper, itineraries. Users land on the web interface, input their origin, destination, and dates, then the system dynamically searches for connections, including self-transfers, across a vast network of carriers. The primary job it handles is uncovering flight combinations that traditional airline alliances or direct booking sites would not display, catering to travelers prioritizing cost savings and route flexibility.
