Trends data is available for nearly any commercial airport in the world and for hotels in hundreds of the most searched destinations. The company also launched a proprietary travel demand benchmark, the Kayak Travel Index, a statistical model that provides a measure of travel demand from analysis of searches on Kayak sites by modeling data for the average combined hotel and flight prices that people select.

Paul English, Kayak CTO and co-founder said, "people have conducted hundreds of millions of travel searches on Kayak in the past year, generating a tremendous amount of data on travel demand trends." English continued, "we're happy to make this information available to the travel press and to the general public."
