Airline Data, Analysis & Insight
Update in progress
Last update to this page was June 2, 2010.
This page will provide an overall summary of the large legacy airlines covered by this website and compare selected metrics for year ending 2009 with year 2000.
Note: Year 2000 was the last year of the most recent industry growth period. It was also the last year before the tragic events of 911 caused the largest financial destruction the airline industry has ever experienced.
American Airlines acquired selected assets of TWA in April of 2001. TWA data is combined with American from year 2001 forward. Where noted, AA and TW data is adjusted proforma for year 2000.
Delta acquired Northwest in October 2008. Year 2008 data for DAL and NWA is primarily from the BTS and may not reconcile with the SEC filings.

Some data has been excluded due to bankruptcy accounting or/and having irrelevant impact for comparison.
Some calculations use cumulative data with a year ending divisor which may cause a distortion of the conclusion.

Glossary of Terms-
ASM— Available Seat Mile. A measure of capacity. ASM’s equal the total number of seats available for transporting passengers during a reporting period multiplied by the total number of miles flown during that period.
RPM— Revenue Passenger Mile. One revenue-paying passenger transported one mile. RPM's equal the number of revenue passengers during a reporting period multiplied by the number of miles flown by those passengers during that period, RPM’s are also referred to as “traffic”.
Yield— The amount of passenger revenue earned per RPM during a reporting period.
RASM— Operating Revenue per ASM. The amount of operating revenue earned per ASM during a reporting period. RASM is also referred to as “unit revenue.”
PRASM— Passenger Revenue per ASM. The amount of passenger revenue earned per ASM during a reporting period. Passenger RASM is also referred to as “unit revenue.”
CASM— (Operating) Cost per Available Seat Mile. The amount of operating cost incurred per ASM during a reporting period, also referred to as “unit cost”.
LF-- Passenger Load Factor — A measure of utilized available seating capacity calculated by dividing RPMs by ASM’s for a reporting period.
Average fare-- Represents the average one-way fare paid per flight segment by a revenue passenger
o/w -- One way
Disclaimer: Data source includes SEC, BTS, labor web sites & Corporate Reports. Except where noted, recognized affiliate revenue and costs were removed to provide mainline comparisons. All data is subject to unintentional errors. For more equivalent comparisons, some UAL, NWA & DAL data immediately pre & post bankruptcy was used.
