The sustainability of transportation systems in Jakarta is under threat from climate change. Better integration and planning of public transportation is an alternative to support land transportation and to solve the congestion problem when heading to Soekarno-Hatta International Airport. Hence, PT Railink, PT Angkasa Pura II, PT Kereta Api Indonesia with its BUMN synergy built rail-based transportation called Airport Train. Moreover, Airport Train is connected with Skytrain in an integrated building as a transferring point. This study analyzes the time integration to travel using the Airport Train from BNI City Station to the Skytrain to reach the passenger destination terminal by observing additional time factors in the integration building or vice versa on the Skytrain – Airport Train trips. The results of the analysis in the form of Train Travel Charts show both on Airport Train - Skytrain trip and Skytrain - Airport Train trip after paying attention to integration factors, there are several schedule conditions that require passengers to depart for the next Airport Train or Skytrain, and worse not accommodate each other at certain times.
