KAYAK also has one of the most advanced and rewarding airline affiliate programs: Earn 50% commissions from clicks, bookings, and ad revenue for flights, hotels, cars, and packages. Easily customize your website for marketing with deep links, widgets, search boxes, white labeling, and API.

The Kayak affiliate program is unique because it typically operates on a Cost Per Click (CPC) or "revenue share" model rather than a flat booking commission. As of 2026, affiliates can earn up to 50% of the revenue that Kayak generates from a user's click. Specifically, when a user clicks a link on an affiliate's site, goes to Kayak, and then clicks through to a final booking provider (like an airline or hotel), Kayak shares the referral fee they receive with the affiliate. In some markets, this equates to roughly $0.40 to $0.95 per click, depending on the travel vertical (flights, hotels, or car rentals). Unlike programs that only pay if a booking is completed, Kayak pays for the "qualified lead," making it a favorite for high-traffic travel blogs. However, the exact rates are dynamic and can vary based on the affiliate's volume and the specific region. The program is managed through the Kayak Affiliate Network directly or through platforms like CJ Affiliate, and it offers a "cookie life" that allows you to earn on return visits for a limited time.
