We plan to issue the sixth in a series of periodic updates to our airline industry metrics report. The report graphically identifies trends in aviation demand and capacity, aviation system performance, airline finances, and service to small communities. The focus of the current edition will highlight concerns related to system performance this summer, especially in key hub markets where new aircraft fleet mixes, expanded low-cost carrier service, and returning demand could result in a level of congestion and delays that rivals the summer of 2000.
