Abstract
The COVID-19 pandemic imposed severe restrictions to the mobility of people worldwide, bringing as a consequent great losses to the air transportation industry. The evaluation of biosafety risk has never been more critical for the recovery of transport and economic activity. Elderly passengers constitute a specially vulnerable population to infectious diseases. The main objective of the present study was to investigate the factors that lead to increased proximity of individuals during the boarding process when elderly passengers are present. In order to do so, an agent-based simulation model was built to represent the boarding process in a Boeing 737 aircraft. The simulated results indicate that elderly passengers are less exposed to contact with other individuals during boarding process when they are the last passengers to come onboard and social distancing actions are taken, although this strategy may increase total boarding time.
