In 2026, you don't make money from KAYAK as a consumer; rather, KAYAK makes money as a travel metasearch engine through a highly diversified B2B revenue model. Their primary income stems from referral and affiliate fees. When a user searches for a flight or hotel on KAYAK and clicks through to a partner site (like Expedia, Booking.com, or an airline's direct page) to complete a booking, KAYAK earns a commission. Additionally, they generate significant revenue through advertising and sponsored listings, where travel providers pay for premium visibility in search results. In 2026, the company has also expanded KAYAK for Business, a platform that monetizes corporate travel management by offering streamlined booking tools for small to mid-sized firms. For individual "side hustlers," the only way to earn money is through the KAYAK Affiliate Program, where website owners or influencers can earn a 50% share of the commission KAYAK receives from clicks and bookings generated through their unique referral links.
