Data Description Cost Data for U.S. Airlines, 90 Oservations On 6 Firms For 15 Years, Source: These data are a subset of a larger data set provided to the author by Professor Moshe Kim. They were originally constructed by Christensen Associates of Madison, Wisconsin. I consider following data set Cost vs Fuel price and Load factor, the average capacity utilization of the fleet. Output
