We released the second in a series of periodic updates of airline industry metrics. Based on data obtained from the Department, FAA, and Air Transport Association, we developed 24 metrics for monitoring airline industry trends related to domestic system demand and capacity, performance, finances, and air service at small airports. The metrics provide decision makers with past, present, and future indicators of domestic air service levels and the general state of the airline industry.
