ABSTRACT
The main goal of this paper is to identify and evaluate the basic factors, affecting the on-time performance of aircraft movement at Almaty Airport based on the statistical data from the flight delays report of Almaty International Airport for the period 2019–2020. Moreover, the effect of the Sars-CoV-2 (COVID-19) pandemic on the flight movement was analyzed. An analysis of the punctuality and regularity of the aircraft movement operating domestic and international scheduled, charter and cargo flights from Almaty Airport for the same period was presented. Special attention was devoted to the detailing and decoding of each delay reason which enabled the authors to determine several factors, that had provoked the occurrence of flight delays. Based on the analysis and with the aim to reduce the number of flight delays, some ideas were theorized to allow airlines and airport services to uncover their hidden reserves. This enables air operators to minimize losses associated with downtime, the damage to corporate reputation and financial losses paid against delay in accordance with The Montreal Convention and/or EU Regulation No. 261/2004. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
