What is the KAYAK affiliate program?
Search for flights, hotels, and rental cars in one place. The KAYAK affiliate program pays publishers 50% commission on qualifying referrals through a recurring model.
The program does not publish a fixed attribution window, so treat the tracking period as short and prioritise content where readers are close to a buying decision.
KAYAK commission rate, cookie and payout structure
Commission: 50% commission. Structure: Recurring. Cookie: not disclosed.
Because payouts recur for the lifetime of the customer relationship, a single conversion compounds month after month. Recurring travel programs usually beat one-off bounties within two to four months, so they reward evergreen content over one-time campaigns.
Who should join the KAYAK affiliate program?
This program fits publishers covering travel, travelbooking and meta-search. If your audience already searches for travel tools, reviews or alternatives, KAYAK slots into existing content without forcing a new topic cluster.
It is a weaker fit for general-interest or low-intent traffic. KAYAK converts best on pages built around a specific problem — pricing questions, migration from a competitor, or a use-case walkthrough — rather than broad top-of-funnel posts.

How to join and promote KAYAK
Apply through the official KAYAK affiliate page (kayak.com). Approval usually requires a live site with relevant content, a visible affiliate disclosure and a short description of how you plan to promote the product.
Once approved, place links where purchase intent is highest: comparison tables, "best of" roundups, alternatives pages and step-by-step tutorials. Disclose the relationship above the fold and keep claims about 50% commission terms accurate, since program terms change without notice.
