What it means in plain language
Unconstrained demand is the theoretical ceiling - what you would have sold if you'd had infinite inventory at the right rate. Forecasting models estimate it to surface compression nights where MinLOS, closeouts, or rate increases will outperform. Without it, you're optimizing a constrained metric (occupancy) and missing real revenue lift.
How Unconstrained Demand fits in the bigger picture
Unconstrained Demand doesn't live alone - it sits inside the Forecasting & Demand category and connects to 3 closely related concepts most working revenue managers track in the same breath. Pair this definition with the related terms below to build a working mental model - definitions in isolation are easy to memorize and easy to misuse.
