Travel tech — short for travel technology — is the broad ecosystem of software, platforms, data systems, and digital tools that power the modern travel industry. It covers everything from the app you use to book a flight to the enterprise platforms that help multinational companies manage billions of dollars in annual travel spend. The term is sometimes used narrowly to mean consumer booking tools, but in practice it spans the entire value chain of travel: planning, booking, operations, customer service, payments, compliance, and analytics.
