What Revenue management means
A seat that departs empty earns nothing, and a seat sold too cheaply early can displace a higher-paying traveller later. Revenue management balances these risks. Early systems were called yield management, but as MIT's airline management course notes, many airlines moved to the term revenue management because chasing yield alone can leave seats empty.
Pricing and revenue management are separate jobs. Pricing teams create fares and fare rules. Revenue management takes those fares as given and decides which booking classes stay open on each flight and date. Systems forecast bookings and no-shows from history, then set booking limits that are revised many times before departure.
Booking classes are usually nested: a higher-value class can always use seats available to a lower one, so a full-fare traveller is never refused while cheaper seats remain. Origin and destination (O&D) control goes further by valuing a seat by the whole journey, so a connecting traveller can be preferred over a local one, or the reverse. Overbooking accepts more bookings than seats to offset expected no-shows.
IATA notes that airline pricing has been dynamic in this sense since the early 1980s, which is why RM is the base on which dynamic pricing builds.
How Revenue management works
A typical RM system runs a continuous cycle of forecasting, optimisation and control for every future flight.
- Collect dataThe system stores historical bookings, cancellations and no-shows by flight, date and booking class.
- Forecast demandIt forecasts remaining demand for each class, and for O&D systems each itinerary and point of sale.
- OptimiseAn optimisation model sets nested booking limits or bid prices that protect seats for higher-value demand.
- Set overbooking levelsAuthorised capacity is raised above physical seats based on expected no-shows and the cost of denied boarding.
- Publish availabilityOpen and closed classes are sent to the airline's inventory, which GDSs and other channels read when shopping.
- Re-optimiseAs bookings arrive, the system re-forecasts and adjusts limits at checkpoints until departure, with analysts able to intervene.
Revenue management in practice
Illustrative nesting. An economy cabin has 140 seats and three classes: Y (full fare), B and M (lowest). Forecast demand is 30 Y and 40 B. The system protects those seats and sets nested limits of Y = 140, B = 110 and M = 70. Once 70 M seats are sold, M closes, but B and Y remain open; a Y request is accepted as long as any seat is left.
Illustrative O&D control. On a flight from Dhaka to Dubai, a Dhaka to London connecting traveller may bring more total revenue than a local Dhaka to Dubai traveller paying a higher fare on that leg. An O&D system can keep a low class open for the connection while closing it for the local market.
Who uses it
Advantages and limitations
Advantages
- Airlines earn more from the same capacity by protecting seats for later, higher-value demand.
- Overbooking reduces revenue lost to no-shows on busy flights.
- O&D control improves network revenue by valuing seats by the full journey.
Limitations
- Forecasting errors can lead to empty seats or turning away profitable demand.
- Availability tied to a limited number of booking classes restricts how finely prices can match demand.
- Overbooking can result in denied boarding, compensation costs and customer dissatisfaction.
Frequently asked questions about Revenue management
What is the difference between revenue management and pricing?
Pricing creates fares, price levels and conditions. Revenue management decides how many seats are available at each of those price levels on each flight and date, by opening and closing booking classes based on demand forecasts.
What does nesting mean in airline revenue management?
Nesting means booking classes share one seat pool in order of value. A higher class can sell any seat still available to a lower class, so the airline never rejects a higher fare while cheaper seats remain unsold.
Why do airlines overbook flights?
Some booked passengers do not show up. By accepting slightly more bookings than seats, based on no-show forecasts, airlines reduce the number of seats that fly empty. The trade-off is the cost and disruption when more passengers arrive than there are seats.
Is yield management the same as revenue management?
They describe the same discipline. Yield management was the earlier name; many airlines switched to revenue management to emphasise total revenue rather than revenue per passenger mile, since focusing only on yield can leave seats empty.
