Percent Dispatch Reliability is defined as the percentage of flights that departed as scheduled without delays or cancellations. Percent Schedule Reliability is defined as the percentage of arrivals and departures that arrived or departed as scheduled without schedule interruptions (delays, cancellations, turnbacks, or diversions). (sources: Holloway [2003] and Friend [1992]).
