About the Cover

This study investigates the performance of selected airports in the study area from 2001 to 2018. Data used for the analysis include passenger throughput, aircraft movement, cargo throughput, mail throughput (output index) and terminal capacity, runway dimension, apron capacity, screening point, ground handling equipment & number of employee (input index) were sourced from FAAN headquarters for each of the airport selected. In the study, Domestic and International travelers were studied for all the selected Airports in the study area. Basic Data Envelopment Analysis (DEA) was used as a technique for the analysis. MaxDEA 7 Software used in running the analysis. Operational performance measures were carried out, showing the airports that are operating at a productive and efficient level amongst the selected airports. From the analysis, the result show that, the international wing of Abuja International Airport, the Domestic wing of Abuja International Airport, the International wing of Aminu Kano International Airport and the Domestic wing of Maiduguri Airport were operating at efficient level of 100% (=1) only in 2018 while the rest of the selected airports are not productive and efficient in 2018 because they were operating below the efficiency score of =1 which is not the ICAO standard in terms of airport benchmarking. Policy implications were made on how to regulate the aviation industry to meet the ICAO standard by benchmarking the inefficient airports using those airports that were operating at =1 (100%) efficiency score.
