There have long been voices calling for a decrease in energy consumption in the commercial airline industry. Though successful efforts have been made in various areas of the industry, resultant achievements cannot be said to be widely known. Here, published data are examined and studies currently made in pursuit of reduction in energy consumption are reviewed. In U.S. airline companies during the period from the first quarter of 1985 to the second quarter of 1986, the flight rate was 0.07-0.25 km/kg and the flight rate multiplied by the number of paying passengers was 7-27 passengers'km/kg. The flight rate multiplied by the weight of paying load was mostly in the range of 1-3 x 10 sup 3 kg'km/kg while fuel accounted for 25-63 percent of the overall costs. In such a situation, some U.S. airline companies have started to replace large airplanes with medium-sized ones, which consume less fuel, because an increase in the number of flights of large airplanes on a route will lead to a decrease in boarding rate, resulting in a decrease in productivity.
