Motivation:So What Has Happened?(Some level of causality seems obvious)
Percent of Continental Airlines Domestic Tickets sold through Internet
1998 1999 2000 2001 2002 2003 2004 2005
Continental Airlines' Average Yield in 2004 Cents
1998 1999 2000 2001 2002 2003 2004 2005
Industry Structure obviously changed…
Domestic US Low Cost Carrier growth.

Rise of Internet
Most customers believe that Airline Pricing Behavior Changed
• But I’m not sure…• We still match and go on sale and run off-peak
sales and amuse ourselves with our alphabet soup of fares and restrictions…
• And DCA3 and PFS et al. limited “Internet-only” and channel-specific activity…
• There have been relatively few innovations: Priceline/Hotwire, weekly specials, clubs,…
The Costs of Distribution Definitely Changed…
Continental Airlines' Average Distribution Expense as a Percent of Fare Paid
1998 1999 2000 2001 2002 2003 2004
But other cost changes overwhelmed it…

We Had Expected
Fragmentation
And, most importantly, Customers Changed
Expectations
& Behaviors
Preliminary Qualitative Study• Method
– 15 open-ended interviews; all referrals; mixed demography and geography, and
– All were “Experienced travelers”• All had purchased in the pre-Internet time• Limitation: homogeneity of age; all between about 30 and 60.• Advantage: Perspective; Most previous studies have been on
students (who never used a TA) or clients of a particular firm
• Data – Analyzed using Glaser and Strauss– Initial set of codes from literature (11): search duration,
dynamics, range, timing, fare levels, fit, loyalty, and adjectives and descriptors of control, trust, choice and cooperation; evidence of co-production
– Final set (50) cluster into 6 categories
weatherhead.case.edu/edm/archive/details.cfm?id=10288&topic=23Or Google: Brunger Impact Airline
Five Findings1. Switch was not perceived primarily about lower
fares; about control & transparency/search breadth.
2. Unexpectedly, the actual search protocols that most respondents perform are quite simple.
- Effects of trip type, FFP status & demography? 3. Some formed new levels of “involvement” with the
Search. Some became “search enthusiasts”. 4. For some, enabled, facilitated, reinforced rich new
set of traditional (and web) social interactions.5. Change with respect to timing, specifically the
decision about when to purchase the ticket.
& They Believe that They Find Lower Fares
Can We See Evidence of the Change?
Yield by Channel
Online Agencies Travel Agents
But this is primarily a market segmentation effect…
Fare Paid for "clearly LEISURE" Itineraries (Net of all fees; fares and inventory were the same)

Internet Agency Traditional TA
On Average, Internet Agency customers pay 11.5% less
What am I going to look at next?
Customers who use Internet/OnlineTravel Agencies (OTAs) to purchase leisure trips pay significantly less (11.5% in our sample) for similar itineraries in the same markets than those who purchase through traditional travel agencies even though the fares and inventory offered by the airlines are identical. The purpose of this study is to examine this Internet Price Effect (IPE).
Other than Transparency Effects, what could account for 11.5%
differential in the IPE?• Trip characteristics
• Customer differences
• Market structure
• The “Value” of the seat
• Then the question is, controlling for these attributes, does IPE persist?
What do I
expect to find???
Using My Regression Equation:
FP= ß0 + ß1*DC + ß2*TC+ ß3*CD + ß4*MS + ß5*OpV + ε

Some Very Early Findings…
• Continental’s Top-25 Markets
• June,2006, every nonstop simple roundtrip
• Only “clearly leisure”• OTA and Traditional Agencies (No CO.com)
• Group size < 9; Coach cabin only
• CO “shipped” the same Fares and Inventory to all channels!
