What it means
Crandall joined American Airlines in the 1970s and rose through finance and marketing roles before becoming its chief executive in the mid-1980s. He ran the company during the years after US airline deregulation, when carriers were suddenly free to set their own fares and routes.
Competition was fierce and many airlines struggled. His best-known contribution is yield management.
An aircraft seat is a perishable product: once the plane departs, an empty seat earns nothing. Airlines learned to split seats into fare classes, sell some cheaply in advance to fill the plane and hold others for last-minute travellers willing to pay more.
American also launched the AAdvantage frequent flyer programme in 1981, which rewarded customers with miles that could be exchanged for travel. It built loyalty, collected data on customers and created a valuable liability on the airline's balance sheet.
Today, miles are sold to banks and retailers, and loyalty programmes can be worth a large share of an airline's value. American's computer reservation system, Sabre, was the technology behind these pricing decisions.
It allowed fares and seat availability to be changed in real time, which made sophisticated pricing possible. The nuance is that Crandall was also controversial.
He was an aggressive competitor, and a famous recorded phone call in the early 1980s led to a competition lawsuit over price discussions with a rival, which was ultimately dismissed. Business students study him for both the innovation and the lessons about competition law.
Beyond pricing, Crandall is remembered for tight cost control and an emphasis on operations. He pushed for efficient scheduling, hub-and-spoke route networks that funnelled passengers through central airports, and labour contracts that gave the airline more flexibility.
These ideas helped American stay profitable when rivals were failing.
In practice
Real-world examples.
Example
A hotel chain uses yield management ideas first popularised in airlines. It sells rooms at lower rates in advance and raises the price as the event date approaches and availability shrinks. The revenue manager reviews the forecast every morning and adjusts the rate bands.
Example
A rental car company creates a loyalty scheme, borrowing from the AAdvantage model. Frequent renters earn points, which gives the company data on its best customers and encourages repeat business. The marketing team uses that data to send targeted offers, such as a weekend upgrade for customers who have not rented for three months.
Example
A theatre uses dynamic pricing for tickets, with different prices for different seats and dates. The manager says the approach comes straight out of the airline playbook developed in the 1980s. Prices for a sold-out concert rise, while mid-week shows are discounted to fill empty rows.
Case study
Seen in the real world.
Skylark Air is a fictional regional carrier created for this illustrative case. Its managers noticed that planes flew 60% full on average but that the best flights were sold out weeks in advance while others left with many empty seats.
Inspired by methods associated with Robert Crandall, the airline divided each flight into four fare buckets and let its system release cheaper seats only while demand was low. The revenue team reviewed booking pace every week, closing the cheapest bucket early on busy flights. In a simple test, it filled 20 extra seats per flight at an average of $120 each without reducing prices for business travellers who booked late.
Over a year, the airline estimated that this added several million dollars of revenue, since the extra passengers cost almost nothing to carry. The extra cost was small items such as a snack, fuel for the added weight and a booking fee. The managers also launched a modest miles scheme to encourage repeat bookings, and the combined effect improved profit without adding aircraft.
Watch out
Common mistakes.
- Thinking yield management is only about raising prices. It is about matching price to demand so that more seats are sold at a profitable level.
- Assuming Crandall invented every part of airline pricing. Many people contributed, and he is best known for driving its adoption at scale.
- Ignoring the competition law lessons. Discussing prices with rivals can be illegal, whatever the intention.
Questions
People also ask.
Why is Robert Crandall important to finance?
His work showed how pricing, data and loyalty programmes can raise revenue from a fixed capacity. It also showed how a balance sheet liability, such as unused miles, can become a major source of value.
What is yield management?
It is the practice of adjusting prices for a limited, perishable resource such as seats or hotel rooms to maximise revenue. The key measure is revenue per available seat, not just the number of seats filled.
Where is the approach used today?
Airlines, hotels, car rental firms, cruise lines, event organisers and even ride-hailing apps use similar methods. Any business with fixed capacity and uneven demand can apply the same logic.
