Airline Service Quality Performance 234 (On-Time performance data): [2011-02]

This CD presents data reported by U.S. certificated air carriers so that information on the air carriers' quality of service can be made available to consumers of air transportation. Carriers within 1% or more of the total domestic scheduled service passenger revenues are required to report data for flights involving any airport in the 48 contiguous states accounting for 1% or more of the domestic scheduled service passenger enplanements. The regulation also provides for the voluntary reporting of a carrier's entire domestic system and voluntary reporting by other carriers. Some of the data elements included are departure, arrival, and elapsed flight times as shown by the Official Airline Guide; the carrier's computer reservation system and the carrier's actual performance; and selected differences among the three sources, such as delay and elapsed time difference. Data are available since 1987.
