Abstract: Flight delays usually occur at airports due to several reasons. These delays affect passengers and would cause several dissatisfactions among them and delays also create financial constraint for airlines as some delays are due to technical faults which had to be repaired by the airlines. This paper had denoted the delays of FireFly Airlines at Subang Airport for a period of five days. Scatter plots and trendlines were produced to represent these delays and correlations were made between the time of the day and the duration of delays. The results were intriguing and several discussions and conclusions were made.
