Trend Analysis of Airline Passenger Trip Delays

The purpose of the Air Transportation System (ATS) is to provide safe and efficient transportation of passengers and cargo. The on-time performance of the ATS is measured by flight-based metrics such as flight delays and flight cancellations. Researchers have shown that flight-based metrics do not accurately reflect the passenger trip experience, and especially underestimate the impacts of cancelled flights and missed connections on passenger trip time. This paper describes a segment-based trend analysis in passenger trip time for the years 2004 and 2005. This paper uses the "estimated passenger trip delay (EPTD)" caused by delayed and cancelled single-segment flights to measure the passenger on-time performance. The EPTD passenger-based metric captures the passenger delays (40M hours) caused by small amount of cancelled flights (<2%). The trend analysis indicates that a small increase in operations (+0.5%) in conjunction with an increase in cancellations (+1.5%) and higher load factors (+5.4%), resulted in 17.4% increase in Estimated Total Passenger Trip Delays in 2005 over 2004. This result reveals the complex nonlinear relationship between the number of operations, the number of cancellations, load factor and passenger trip delays.
