Jakub Lončák, better known online as Kuba, is a Czech travel entrepreneur and the founder of Letenky od Kuby and Komunita od Kuby. What started as an Instagram page sharing flight deals has grown into a community of thousands of Czech and Slovak travelers, built on Kuba's real-world experience spotting cheap flights, airline errors, and limited-time offers before they disappear.

Before finishing high school, Jakub had already flown more than fifty times in a single year — rarely paying more than the equivalent of pocket change per ticket. With a background in content marketing and a passion for making travel accessible to everyone, he has built a loyal following of over 200,000 people on Instagram who rely on his tips to save real money on every trip they take.
