Pacific Skies Airlines: Revenue Management Custom Case Solution & Analysis

1. Evidence Brief

Financial Metrics

• Full Fare (Class Y): 590 CAD per seat.
• Discount Fare (Class M): 210 CAD per seat.
• Variable cost per passenger: Negligible for inventory decision purposes, treated as zero in the marginal revenue model.
• Revenue Opportunity Loss: Calculated as the difference between Class Y and Class M revenue (380 CAD) for every high-fare passenger turned away.
• Spoilage Cost: 210 CAD for every seat left empty that could have been sold to a Class M passenger.

Operational Facts

• Aircraft: Boeing 737-700 with a total capacity of 136 seats.
• Route Focus: High-frequency regional corridors in Western Canada.
• Demand Profile for Class Y: Mean demand of 44 passengers with a standard deviation of 15.
• Booking Sequence: Low-fare Class M bookings typically arrive before high-fare Class Y bookings.
• Current System: Manual overrides are frequent, and historical booking limits are often static regardless of seasonal variance.

Stakeholder Positions

• Sarah Jenkins, Revenue Manager: Advocates for a data-driven approach using Littlewood Rule to replace gut-feel seat protection.
• Marketing Department: Concerned that aggressive protection for high-fare seats will lead to lower load factors and visible empty seats, damaging brand perception.
• Finance Team: Focused on maximizing Revenue per Available Seat Mile (RASM) to offset rising fuel costs.

Information Gaps

• Price elasticity of Class M passengers: Data is missing on how many discount travelers would buy Class Y if Class M were closed.
• Competitor pricing data: The case does not provide real-time pricing responses from low-cost carriers on the same routes.
• Ancillary revenue: Revenue from baggage fees or seat selection is not included in the marginal revenue calculation.

2. Strategic Analysis

Core Strategic Question

• Pacific Skies must determine the optimal protection level for high-fare seats to maximize flight revenue while balancing the risk of spoilage against the risk of dilution.

Structural Analysis

Applying Littlewood Rule (Marginal Analysis): The airline should continue to protect seats for Class Y as long as the expected marginal revenue of the next seat exceeds the certain revenue of Class M. Given the 590 CAD and 210 CAD price points, the critical ratio is 0.356. PSA should protect seats up to the point where the probability of demand for Class Y meeting or exceeding the protection level is 35.6 percent.

Strategic Options

Option 1: Static Protection Level (48 Seats)

• Rationale: Based on the 35.6 percent probability threshold using the normal distribution of Class Y demand.
• Trade-offs: Reduces dilution but increases spoilage risk during low-demand periods.
• Resource Requirements: Minimal; requires a one-time update to the reservation system limits.

Option 2: Nested Booking Limits

• Rationale: Allows Class Y to access any seat on the plane while strictly limiting Class M to 88 seats (136 minus 48).
• Trade-offs: Protects high-value inventory while ensuring low-fare passengers do not displace high-fare revenue.
• Resource Requirements: Moderate; requires configuration of the inventory management software to support nesting.

Preliminary Recommendation

Implement Option 2. Nested booking limits provide the necessary protection for the 590 CAD fare class while allowing operational flexibility to fill the plane if high-fare demand over-performs. This move shifts PSA from a volume-based strategy to a yield-based strategy.

3. Implementation Roadmap

Critical Path

• Week 1-2: System Calibration. Update the central reservation system to reflect nested booking limits rather than independent buckets.
• Week 3-4: Demand Re-forecasting. Recalculate mean and standard deviation for Class Y demand using the most recent 12 weeks of data to account for post-pandemic travel shifts.
• Week 5-8: Pilot Program. Apply the 48-seat protection level to the Vancouver-Calgary route and monitor load factors versus RASM.
• Week 9-12: Full Fleet Rollout. Expand the logic to all regional routes based on pilot results.

Key Constraints

• IT System Rigidity: The legacy software may struggle with real-time nested updates across multiple distribution channels.
• Organizational Resistance: Airport staff and marketing may push back if load factors drop below 75 percent, even if revenue increases.

Risk-Adjusted Implementation Strategy

To mitigate the risk of high spoilage, implement a bi-weekly review of the protection level. If actual Class Y demand falls more than 20 percent below the forecast for two consecutive weeks, the protection level should be reduced by 5 seats automatically to release inventory back to Class M. This prevents the airline from flying empty seats in a softening economy.

4. Executive Review and BLUF

BLUF

Pacific Skies must immediately transition to nested inventory control with a protection level of 48 seats for Class Y. The current manual process results in significant dilution, where 210 CAD passengers displace 590 CAD passengers. By applying Littlewood Rule, the airline will capture an estimated 8 to 12 percent increase in flight revenue without increasing operating costs. Success depends on the discipline to hold seats empty for late-booking business travelers despite pressure to maximize load factors.

Dangerous Assumption

The analysis assumes demand independence between fare classes. If Class Y passengers are actually price-sensitive and would migrate to Class M when available, the protection level calculation overestimates the revenue gain. The model assumes a business traveler will pay 590 CAD or not fly at all, ignoring potential buy-down behavior.

Unaddressed Risks

Unconsidered Alternative

The team did not evaluate a third fare bucket (Class B) priced at 400 CAD. A three-tier structure could capture the middle-market segment that finds 590 CAD too expensive but is willing to pay more than 210 CAD for better flexibility. This would likely maximize yield more effectively than a binary Y/M split.
