This document discusses revenue management theory and practice. It summarizes that revenue management has established principles including demand forecasting, optimization, and overbooking models. However, airlines face many constraints applying these principles including strategic differences across airline types, legal/regulatory issues, technical system limitations, organizational challenges, and competitive pressures. Therefore, revenue management analysts must understand both the underlying science and its real-world implementation given the complex constraints faced by individual airlines.
2. Theory and Practice
• Revenue Management is now an established science. The
science of RM includes:
– Estimation of price elasticities
– Statistical analyses of demand patterns
– Regression-based forecasting
– Overbooking based on no-shows & cost of over-booking
– Mathematical optimization including linear programming
• On the other hand, there are a multitude of constraints to
an individual airline’s application of the science
– Strategic, Financial, Legal, Technical, Organizational, Competitive
• A revenue management analyst today should understand
the science but he must also understand its use – and
misuse – in real world challenges his airline faces.
4. Legal/Regulatory
• In the U.S., legal constraints
exist:
– In both raising and lowering
fares
– On pricing in airline partnerships
• Over the past year, the
government has shown new
interest in regulating ancillary
fees and e-merchandising

5. Systems/Technical
• Every RM system has data limitations and model
assumptions which inhibit optimality
• System providers regularly implement “improvements”
– Not appropriate for all users; not fast enough for others
• Pricing interaction with Operations, Marketing,
Customer Service, Loyalty calls for integrated systems
– In addition to links to third party systems

6. Organization and Culture
• The “ideal” RM organization
doesn’t exist
– Trade-offs in costs, flexibility,
responsiveness, control
– …Within RM
– …Between RM & rest of
organization
• “Culture” and capabilities are bigger than just RM
– Conflict mgmt, decision-making across the airline
– Skills, experience, talent management
8. Competitive
• “This industry is always in
the grip of its dumbest
competitor.”
– R. L. Crandall, 1992
• Competitive issues remain
the largest constraint to
optimized, rational pricing
