Blockchains are being integrated into all business processes across all industries. This technology is revolutionizing the industry by addressing all inefficiencies and making operations seamless and smooth. Blockchain has numerous applications in the travel industry, like enhancing customer experience, simplifying transactions for travelers, and facilitating seamless cross-border operations for businesses.

Blockchain comes as a solution to all the problems related to human error. This chapter analyzes various applications of blockchain technology in the travel industry, thereby making travel smart, smooth, and seamless.
