Assignment
We have been asked by Airlines for America (“A4A”) to provide an
independent economic assessment of the current state of airline
industry competition and consumer choice for U.S. air travelers.
Our analysis relies on a variety of publicly available data and
information sources, including:
Data from various U.S. Department of Transportation (“DOT”) databases,
including the Origin & Destination Survey (“DB1B”), Form 41, On-Time
Performance and T-100 databases.
OAG schedule data.
SEC filings, news releases and other publicly available airline industry
information sources.
Published academic research.

Summary of Findings
An analysis using established criteria for assessing airline industry
competition demonstrates that there is robust competition in the U.S.
airline industry. In particular:*
U.S. consumers currently enjoy a wide array of choices among competing
airlines and products.
The “Southwest Effect” is alive and well and there are now several rapidly
growing carriers that substantially lower fares in the markets in which they
compete.
Robust competition spurred by both the continued growth of lower cost
carriers and the expansion by all carriers at competitors’ hubs has resulted in
fare levels among the lowest in U.S. aviation history.
Following external shocks that severely impeded the economics of serving
small communities, service at small airports has been growing.
Improved financial health has enabled U.S. carriers to invest heavily in their
products and services, create thousands of well-paying airline jobs, and
substantially increase compensation levels for airline employees.
The U.S. airline industry’s operational performance and customer
satisfaction levels are at all-time highs.

1. U.S. Consumers Currently Enjoy an Abundance of
Choices for Air Travel at Some of the Lowest
Prices in History

Overall, the Average Number of Competitive Choices for Air Travel Has
Increased Over the Past Two Decades
The average number of competitors per
city-pair has increased consistently for
almost two decades.
For example, between Dallas and New York, a
market with close to 3,000 passengers per day
each way (“ppdew”), the number of
competitors increased from two to five
including the addition of two low cost carriers.
Similarly, between Austin and Los Angeles (over
800 ppdew), the number of competitors
increased from three to five (including two low
cost carriers one of which is new).
Simply put, the lack of entry barriers has
made it easy for all carriersincluding low
cost and ultra low cost carriersto continue
entering and expanding into more city-
pairs.
Average Number of Competitors on U.S. Domestic City-Pairs
Sources: U.S. DOT DB1B Database.
Notes: A carrier is defined as a competitor on a city-pair if it has at least 5% of O&D passengers. Average number of competitors is weighted across city-pairs by
passengers. Airports in the following metropolitan areas are grouped: Chicago (ORD, MDW), Cincinnati (CVG, DAY), Cleveland (CLE, CAK), Dallas (DFW, DAL), Houston
(HOU, IAH), Los Angeles Basin (LAX, BUR, LGB), Miami (MIA, FLL), New York (LGA, JFK, EWR), San Francisco/Bay Area (SFO, OAK), Washington DC/Baltimore (DCA, IAD,
BWI), and Tampa (TPA, PIE).

The Number of Competitive Choices per City-Pair Remains
Robust Across Cities of All Sizes
Sources: U.S. DOT DB1B Database; T100; FAA (https://www.faa.gov/airports/planning_capacity/passenger_allcargo_stats/categories/).
Notes: Bars show average number of competitors per city-pair where one end of each city-pair includes cities in that size category (based on 2007 enplanements). A carrier is defined as a
competitor on a city-pair if it has at least 5% of O&D passengers. Average number of competitors at each city is computed as the passenger-weighted average of competitors on all city-pairs
from that city. Average number of competitors for each city size is calculated as the simple average across cities in a size category. City categories are based on 2007 enplanements with:
Large Cities greater than 1% of U.S. enplanements, Medium Cities greater 0.25% of U.S. enplanements, Small/Nonhub less than 0.25% of U.S. enplanements and more than 10,000 annual
enplanements. Size cutoffs based on FAA airport size definitions. The following airports are grouped into cities: Chicago (ORD, MDW), Cincinnati (CVG, DAY), Cleveland (CLE, CAK), Dallas
(DFW, DAL), Houston (HOU, IAH), Los Angeles Basin (LAX, BUR, LGB), Miami (MIA, FLL), New York (LGA, JFK, EWR), San Francisco/Bay Area (SFO, OAK), Washington DC/Baltimore (DCA, IAD,
BWI), and Tampa (TPA, PIE). All other cities are individual airports.
Overall and at large cities, there has been
an increase in the average number of
competitors per city-pair since 2007.
There was a slight decrease in the number
of competitors per city-pair from medium
and small cities, but the average city-pair
to/from small cities still has close to two
competitors while medium cities average
over three competitors.
The worsening economics of 50-seat (and
smaller) regional jets and sharp declines in
short-haul travel due to the post-9/11
“hassle factor” have been the primary
causes of the decrease in service at smaller
cities.

The Assertion That “The ‘Southwest Effect’ is Long Gone” Has Been
Proven to Be Untrue
Some industry observers have
asserted that since its merger
with AirTran “The ‘Southwest
Effect’ is Long Gone.”*
