benchmarks of the performance of air transport service companies in improving
competitiveness. Flight delays generally occur due to certain factors that

The study was conducted at Yogyakarta Adisutjipto International Airport
and the research time during the time specified for the method used in the
research in this thesis is the Fishbone Diagram on the analysis of on time
performance at Yogyakarta Adisutjipto International Airport. The results of this
study are expected to provide a comprehensive and systematic picture of the
identification and optimization of on time performance of departures for the
airlines concerned

environmental and commercial categories of 59% (Environment 33% and
Commercial 26%) and sub-factors Accessibility to Airport, Ground Support
Equipment (GSE), Millitary training, Technical interruption of aircraft, Rotation
of 48% with the percentage of each as follows: Accessibility to Airport 12%,
Ground Support Equipment (GSE) 11%, Millitary training 9%, Technical
