Kiwi sells air and ground tickets directly to customers through a network of partners - carriers, OTAs, tour operators, technology providers and metasearch sites. But differently from competitors, Kiwi has developed a technology called “virtual interlining” that allows the company to combine tickets from different providers and offer them as an unique itinerary. Kiwi then purchases the tickets from the carriers, issues the e-ticket and guarantees the price booked even if it goes up (until a reasonable limit).
