About HTS Media

HTS Media is Hopper’s advertising and media division, built to help travel brands, destinations, and suppliers connect with travelers at scale.

Our mission is to build the travel industry’s leading retail media network, turning advertising into a major driver of profitability for Hopper and our partners, much like Instacart, Uber, and Amazon have done in their sectors.
