Purpose: The number of passengers, luggage, and cargo served at the airports increases atcertain times due to flight density (peak hours). Due to the long queues at check-in desk duringpeak hours, there may be delays in flight operation processes. In addition, it is estimated thatcheck-in queue times will increase even more in accordance with Covid-19 social distance rules. The aim of the study is to calculate the possible effects of Covid-19 measures on check-inqueues at small-scale airports. For this purpose, the number of check-in desks that should beopened at peak hours was evaluated by simulation method at Erkilet airport. Design/methodology:In the first part of the study, the effects of Covid-19 measures on theaviation industry and airport management issues are presented with the literature research.Information about Erkilet airport was collected by using qualitative research method and theintensity experienced during peak hours was simulated in the ARENA-TRIAL simulationprogram. Two 3D scenarios were prepared, including the pre and post COVID-19 socialdistance constraints.Findings:In the analysis section of the research, check-in queue times and staff productivitywere calculated for both scenarios. In the calculations, comments were made regarding theproblems that may occur during the peak hours of the airport within the scope of the check-indesk and COVID-19 social distance constraints. Based on the analysis outputs of the simulationprogram, recommendations were made for small-scale airports. Originality/value: The effect of COVID-19 on the check-in process in small-scale airports wasexamined for the first time with simulation method.
