The aviation sector is evolving with the support of digital transformation, driven by demands for safety, speed, and accessibility. Increased passenger/cargo traffic, operational complexity, and costs are creating a need for innovation in the aviation sector. In this context, artificial intelligence has become a necessary element for achieving a competitive advantage and ensuring lasting success in the sector, in addition to reducing operational costs and improving passenger experience. Airports, influenced by these technological advancements, have also turned to the "Smart Airport" concept. Smart airports leverage Industry 4.0 technologies such as the Internet of Things (IoT), Big Data, Biometric Technologies, and Artificial Intelligence to improve customer experience and increase capacity utilization. These systems are being used at Singapore Changi Airport, one of the world's busiest airports.

Singapore Changi Airport (SIN), known for its safe, uninterrupted, and efficient services, owes its success to its customer-centric approach to excellent service as well as its seamless implementation of advanced technologies. This technology-enabled framework forms the basis of Singapore Changi Airport's "Smart Airport" vision. Singapore Changi Airport, within the framework of its Smart Airport vision, aims to increase operational efficiency and improve customer experiences through user-centric designs by leveraging sensors, data analysis, and artificial intelligence. The Singapore Changi example offers lessons for developing airports on the necessity of establishing data-driven systems in strategic decision-making, focusing on predictive analytics systems in operational processes, employing AI experts, and promoting digital literacy training for employees.
