Revenue management system (RMS)
A revenue management system (RMS) is software that forecasts demand and recommends or sets prices and inventory controls — which booking classes stay open on a flight, which rates and stay restrictions apply to a hotel night — to earn the most from fixed, perishable capacity.

What an RMS does
- Forecast. Expected demand per flight or night, from booking history, booking pace, cancellations, seasonality and events.
- Optimise. How much capacity to sell at which price, and how much to hold back for later, higher-paying demand.
- Control. Opens and closes fare classes for airlines; sets best available rate, minimum stays and closures for hotels.
- Overbook. Sells slightly beyond capacity where no-shows are predictable.
Airline and hotel RMS compared
| Airline | Hotel | |
|---|---|---|
| Unit sold | A seat on a flight leg or itinerary | A room-night, often across a multi-night stay |
| Main lever | Booking-class availability | Rate level and stay restrictions |
| Competitor data | Competing fares on the route | A competitive set's rates, from rate shopping |
| Output goes to | Reservation system and distribution | PMS and the channel manager |
The room to price freely
In the EU, Article 22(1) of Regulation (EC) No 1008/2008 lets Community air carriers freely set fares for intra-Community air services, which is the legal space airline revenue management operates in. Disclosure duties still apply to how the resulting price is shown, as described under dynamic pricing.
What it means for price data
An RMS updates prices whenever its forecast moves, so any single observation is a snapshot. Useful datasets are time series with a fixed cadence and the market recorded; the storage side is in storing price time series, and the airline mechanics in how airline revenue management works.
FAQ
Questions
Something not covered? Write to contact@arcproxies.io.
Is a revenue management system the same as dynamic pricing?
Dynamic pricing is the outcome: prices that change with demand and time. A revenue management system is one way of producing it, by forecasting demand and setting prices and availability controls.
Do revenue management systems use competitors' prices?
Many do, especially in hotels, where a competitive set's public rates are a standard input alongside the hotel's own bookings and forecast.
How often does an RMS change prices?
As often as it is configured to re-optimise and as demand moves — for busy dates, several times a day is not unusual. Measuring the actual frequency for a route or hotel takes sampling at a fixed cadence.
Who uses revenue management systems?
Airlines, hotels, car hire firms, cruise lines, rail operators and event venues — any business selling fixed capacity that expires on a date.
