Revenue Management

Overbooking

Deliberately selling beyond physical capacity to offset expected no-shows and cancellations.

Academic definition

Overbooking is the deliberate practice of accepting more reservations than a hotel has physical rooms, in order to offset the rooms expected to go unsold through no-shows, cancellations, and early departures. Because a room left empty by a no-show cannot be resold after the night passes, a calibrated level of overbooking protects against lost revenue from unrealised bookings. The overbooking limit is derived from historical no-show and cancellation rates by segment, day of week, and season, often expressed through a wash factor. The risk is that more guests arrive than can be accommodated, requiring the hotel to relocate, or "walk," guests to other properties at its own cost and reputational expense. Effective overbooking balances the expected revenue recovered against the expected cost of walking guests, and is recalibrated as forecasts and pickup data evolve toward arrival. It depends on accurate measurement of no-show and cancellation behaviour.

Worked example

With 100 rooms and an expected 8% no-show and wash, the overbooking limit ≈ 100 ÷ (1 − 0.08) ≈ 109 reservations — capturing revenue on the rooms no-shows would otherwise leave empty.

The ProfitPAR^™ lens

Overbooking is a calculated bet, and like any bet it should be sized on profit, not just on filling rooms. The upside is the revenue rescued from a room a no-show would have left empty forever; the downside is the cost of walking a guest — relocation, transport, goodwill, and a damaged relationship that dents lifetime value. ProfitPAR™ frames the decision as an expected-value problem in profit terms: overbook to the point where the margin recovered from avoided empty rooms still exceeds the expected cost of the walks it causes. Done crudely it trades a small revenue gain for an expensive reputation hit; done on the leak math, it converts forecast no-shows into retained profit.

Size the overbook on the margin recovered versus the cost of the walk, not on heads.
