Cabin Revenue Model

Stochastic spill model with configurable cabin classes

Cabin Classes

Enable 2–5 classes (top → bottom by fare). Everything below adapts to the enabled set.

Global Settings

Model Type

Uses a Normal distribution with K-factors for demand variability.

Demand Distribution

Symmetric demand around the mean with σ = K × mean.

K-Factors (Demand Variability)

K-factor controls demand variability: σ = K × mean. Higher K means more spill even when mean demand is below capacity.

Nested cabin spill

Same-flight cross-cabin recapture is active (downgrades and upgrades).

Load Factor Cap

Recapture Matrix

Fraction of each cabin's spill recaptured. Rows are the spilling cabin (from), columns the receiving cabin (to). Upper-right = downgrades, lower-left = upgrades into leftover seats, Net = recapture elsewhere in the network.

Any remaining spill after these fractions is treated as lost to competitors or abandoned demand.
