2. Southwest Airlines
• Founded in 1971 by Rollin King and Herb
Kelleher
• The third-largest airline in the world
• The United States’ most successful low-fare,
high frequency, point-to-point carrier.
• Known as a “discount airline” since 1973
- offers low fares
- no-frills service
- basis for Southwest's popularity and rapid growth
3. Corporate Culture
• Tickets must be bought from the airline itself, the
phone or online
• Extra Rapid Rewards
- frequent flier program
- credits for online booking users only
• Customers are assigned to a boarding group
depending on check-in time
- find their own seats on the plane
• Colorful boarding announcements and crews that burst
out in song instead of no video entertainment
• Meal service is less than on historically full service
airlines
4. Basis for profitability
• Fuel hedging
– Purchased fuel options for years in advance to
smooth out fluctuations in fuel costs
– substantially increased its hedging in 2001 in
response to projections of increased crude oil prices
– Advantaged after Sep. 11, 2001 attack, the oil shock
from Iraq War, and Hurricane Katrina
• Operated only one model of aircraft
– Boeing 737, medium range-narrow body commercial
passenger jet aircraft
– easy to replace parts and ground support equipment
5. The Southwest Effect
• A trend that indicated the success and
profitability of Southwest’s business model
– less expensive than driving between two
points in the early 1970s, during the first
major energy cost crisis in the U.S.
• Basis of lean operations and high aircraft
utilization
• When a low fare carrier enters a market,
profit grows dramatically
6. Fight against high speed rail
• In 1991 Texas TGV Corporation planed to connect the
“Texas Triangle” (Houston – Dallas – San Antonio) with a
privately financed high speed train system at a lower fare
rate
– The same model Southwest Airlines used 20 years
earlier to break in to the Texas market
• The original estimated cost was $5.6 billion, but the task
of securing the necessary private funds proved
extremely difficult
• Southwest Airlines created legal barriers to prohibit the
consortium from moving forward with the help of
lobbyists.
• In 1994, the Texas TGV Corporation has failed and
withdrew high speed rail development
– lost $40 million to be invested
7. Conditions for price discrimination
• A firm must have some market power to price
discriminate
– The demand curve the firm faces must be
downward sloping
• Southwest knows that it can attract more
customers at lower fare price
• The firm must have some information about the
different amounts people will pay for its product.
– Southwest must know how reservation prices or
elasticities of demand differ across consumers
• A firm must be able to prevent resale, or arbitrage.
– Customers need to present an identity card before
boarding
8. Third-Degree Price Discrimination
• The firm identifies different consumer groups, in
the market, each with a different demand curve.
– Southwest Airlines recognizes that any given flights
has different types of travelers
• business travelers vs. vacation travelers
• To maximize profit, the firm sets a price for each
group by equating marginal revenue and
marginal cost.
– Equivalently, by using the inverse elasticity pricing
rule (IEPR)
9. The Inverse Elasticity Pricing Rule
(IEPR)
• The rule stating that the difference
between the profit-maximization price and
marginal cost, expressed as a percentage
of price, is equal to minus the inverse of
the price elasticity of demand.
10. Price elasticity of demand
• The percentage change in quantity demanded
(Q) that occurs in response to a percentage
change in price (P)
• Estimates of the price Elasticity of demand for Airline
Category Estimated EQ,P
Airline travel, leisure - 1.52
Airline travel, business - 1.15
*Source: Tea Hoon Oum and Jong-Say Yong, “Concepts of Price Elasticities of Transport Demand and
Recent Empirical Estimates,” Jounal of Transport Economics and Policy (May 1992):139-154
11. Examples
• Using the inverse elasticity pricing rule to determine the ratio of
between tickets for business (PB) and vacation travelers (PV)
– The IEPR tells that (PB – MC)/PB = -(1/e)
• Substitute the estimated price elasticity of demand for
business travelers, e = -1.15
• solve for MC: MC = 0.13 PB
– The IEPR also tells that (PV– MC)/ PV = -(1/e)
• Substitute the estimated price elasticity of demand for
vacation travelers, e = -1.52
• solve for MC: MC = 0.342 PV
• Equate these two expressions for MC: PB /PV = 0.342/0.130 = 2.63
• Thus, Southwest Airlines will maximize profit by charging
2.63 times as much for a business travel ticket as it
charges for vacation travel ticket
– (the exact prices of the tickets will depend on the marginal cost)
12. Advertising campaigns
• “Just Plane Smart”
• “The Somebody Else Up There Who
Loves You”
• “THE Low Fare Airline”
• “Symbol of Freedom”
• “Wanna get away?”
– “[ding] You are now free to move about the
country”
13. Livery
• Some southwest
planes feature special
themes, rather than
the normal livery
– Shamu One/Two/Three
– California One
– Arizona One
– Lone Star One
– Triple Crown One
– Sliver One
14. 2005 Financial Statistics:
• Net income: $548 million
• Total passengers carried: 88.4 million
• Total RPMs: 60.2 billion
• Passenger load factor: 70.7 percent
• Total operating revenue: $7.6 billion

16. Incidents and Accidents
• On March 5, 2000, Southwest Airlines Flight
1455 overran a runway at the Burbank airport in
California
– Leaving 43 injured but no fatalities
– Resulted in the dismissal of the pilots
• On December 8, 2005, Southwest Airlines Flight
1248 skidded off a runway at Midway Airport in
Chicago, Illinois, in heavy snow conditions
– A young boy was killed in a car struck by the plane
after it had skidded into a street
– Several minor injuries reported from passengers
onboard the aircraft and on the ground
17. Conclusion
• Southwest Airlines uses third-degree price
discrimination to fill the plane with
travelers in the most profitable way
• Depending on the price of elasticity of
demand for tickets
– Charge a higher price for business travelers
who have relatively inelastic demands
– Charge a lower price for vacation travelers
who have relatively elastic demands
