In the period of coronovirus pandemic, a particularly important tasks of the airport are to reduce the time of passengers processing at check-in counters, baggage drop-off points and passport control counters, as well as to minimize contacts between people. All this can be achieved due to the implementation of the self-service check-in systems for passengers and their baggage, automatic boarding, self-service kiosks for reporting about lost baggage, etc. Insufficient number of processing points leads to forced delays, formation of passengers congestion at restricted areas. The article demonstrates how to use the queuing theory models to estimate the impact of the newest technologies on passengers processing at the airport. The automatic passengers check-in system has been considered as an example of the innovative technology for air passengers processing. Efficiency of the automatic passengers check-in system with self-service bag drop points implementation at the largest international airport of Western Ukraine Danylo Halytskyi International Airport Lviv has been proved, using queing systems models.
