Managing disease transmission risks at airports during the COVID-19 pandemic is critical. This study develops a simulation model for passenger handling processes at Terminal 3, Departure Area, Soekarno-Hatta International Airport, focusing on security checks, immigration, and boarding lounges. The model, tailored for Garuda Indonesia passengers, uses statistical distributions to simulate queuing dynamics and viral spread. Results show that factors such as the number of counters, ventilation, air purifiers, and mask-wearing policies significantly reduce SARS-CoV-2 transmission risks. External factors like passenger volume (FNP) and schedule adjustments also influence exposure. Domestic passengers inhale an average of 1.17×10?? quanta, while international passengers inhale 1.19×10?? quanta. The domestic boarding lounge is the area with the highest virus concentration, followed by the international lounge, check-in, immigration, and security checks. Masks are the most effective in mitigating risks, followed by optimizing the number of counters. Ventilation, air purifiers, and operational adjustments also contribute but have lesser impacts. This model reliably represents Garuda Indonesia's passenger handling processes at Terminal 3, enabling the estimation of virus exposure under various operational scenarios. The findings offer practical insights for improving pandemic risk management strategies in airports, ensuring safer passenger handling an reduced transmission risks.
