The challenges that often occur at the departure terminal are flight service users who pay less attention to the estimated travel time, conditions on the way to the airport (congested), parking locations that are far from the departure terminal, the antigen validation process, which takes more time, so that flight service users experience delays in registering at the departure terminal. Check in the airline counter at the departure terminal. Flight delays are often caused by lost passengers and unable to find their way to the right gate on time. The purpose of the study was to determine the factors that influence the use of mobile devices to determine the position of passengers while at the departure terminal. The research method used with this type of research is the Hasanuddin Airport Case Study with a description method approach. The research population is the public facilities available at the Sultan Hasanuddin Airport terminal, while the research sample is the facilities available at the departure entrance to the waiting room gate. The data collection technique is through Literature Study and Field Observation, while the data collection instrument is carried out by distributing questionnaires to passengers using flight services data analysis techniques by processing questionnaire data using the SPSS application. The study results show that the factors that greatly influence the positioning of passengers at the terminal by using mobile devices are social factors in the aspects of knowledge and abilities of passengers (habit) and the passenger's intention to use the application.
