United and Continental's combined consolidated traffic (revenue passenger miles) in August 2011 decreased 2.7 percent versus pro forma August 2010 results on a consolidated capacity (available seat miles) decrease of 1.6 percent. The carriers' combined consolidated load factor in August 2011 was down 0.9 points compared to the pro forma results from the same period last year.

United and Continental's August 2011 combined consolidated and mainline passenger revenue per available seat mile (PRASM) each increased an estimated 10.5 to 11.5 percent compared to the pro forma results from August 2010.

Hurricane Irene impacted United and Continental's operations in August, reducing the company's revenue results by approximately $40 million in the month and reducing consolidated capacity. As a result, consolidated PRASM year-over-year growth improved by approximately 1 percentage point, which is included in the above estimate.
