Digital technology in passenger door-to-door air travel

This paper aims to provide an insight into how to use the concept of digital twin (DT) to optimize the door-to-door (D2D) air travel process from a passenger perspective. In this study, a digital and seamless D2D air travel model has been developed based on passengers' real needs, and its practicality and efficiency have been examined by digital twin simulation. In the model, passengers' actual travel times are compared with the estimated route times at each waypoint in the trip. If passengers fail to arrive at points at the estimated time, the model will calculate the real-time information and infer if delays/ disruptions will occur in the following stages. Then users can choose the optimized alternatives provided by the model, which ensures a smooth travel process. Thus, by applying this digital D2D model, passengers' air travel experience can be improved and their loyalty to the aviation industry can also be enhanced.
