(b) Available seat mile ("ASM") — A basic measure of production. One ASM represents one seat flown one mile.
(c) Passenger load factor — The percentage of available seats that are filled with revenue passengers.
(d) Yield — A measure of airline revenue derived by dividing passenger revenue by RPMs and expressed in cents per mile.
(e) Passenger revenue per available seat mile ("PRASM") — Passenger revenues divided by ASMs.
(f) Operating cost per available seat mile ("CASM") — Operating expenses divided by ASMs.
(g) Passenger enplanements — The number of passengers on board an aircraft, including local, connecting and through passengers.
(h) Block hours — The hours measured from the moment an aircraft first moves under its own power, including taxi time, for the
purposes of flight until the aircraft is docked at the next point of landing and its power is shut down.
(i) Average stage length — The average of the distances flown on each segment of every route.
(j) Average passenger journey — The average one-way trip measured in miles for one passenger origination.
(k) Express statistics include Piedmont and PSA, as well as operating and financial results from capacity purchase agreements with Air
Wisconsin Airlines Corporation, Republic Airways, Mesa Airlines, Inc. and Chautauqua Airlines, Inc.
(l) Total revenue per available seat mile ("RASM") — Total revenues divided by total mainline and Express ASMs.

Operating revenues:
Mainline passenger $ 6,752 $ 8,183 (17.5)

Total operating revenues $ 10,458 $ 12,118 (13.7)
Total operating revenues in 2009 were $10.46 billion as compared to $12.12 billion in 2008, a decline of $1.66 billion or 13.7%.
Significant changes in the components of operating revenues are as follows:
• Mainline passenger revenues were $6.75 billion in 2009 as compared to $8.18 billion in 2008. Mainline RPMs decreased 4.4% as
mainline capacity, as measured by ASMs, decreased 4.6%, resulting in a 0.2 point increase in load factor to 81.9%. Mainline
passenger yield decreased 13.7% to 11.66 cents in 2009 from 13.51 cents in 2008. Mainline PRASM decreased 13.5% to 9.55
cents in 2009 from 11.04 cents in 2008. Mainline yield and PRASM decreased in 2009 due to the decline in passenger demand and
weak pricing environment driven by the global economic recession.
• Express passenger revenues were $2.5 billion in 2009, a decrease of $376 million from 2008. Express RPMs decreased by 2.6% as
Express capacity, as measured by ASMs, decreased 3.9%, resulting in a one point increase in load factor to 73.6%. Express
passenger yield decreased by 10.7% to 23.68 cents in 2009 from 26.52 cents in 2008. Express PRASM decreased 9.5% to 17.42
cents in 2009 from 19.26 cents in 2008. The decreases in Express yield and PRASM were the result of the same passenger demand
declines and weak pricing environment discussed in mainline passenger revenues above.
