walk-in

Refers to guests who arrive at a hotel, tour office, attraction, or other travel service provider without a prior reservation, seeking immediate service or same-day booking. In the operational fabric of tourism, these guests represent spontaneous demand, often driven by last-minute decisions, flight disruptions, or on-the-ground recommendations. For front desks, ticket counters, and local agents,…

product allocation

Refers to the controlled distribution of a finite travel inventory—such as hotel rooms, airline seats, tour spots, or cabin categories—across different sales channels, markets, and time periods. In the operations and distribution landscape, it is the quiet discipline that ensures the right product is available to the right customer, at the right price, through the…

last minute

Refers to travel products—such as flights, hotel stays, package holidays, cruises, or tours—booked very close to the intended departure or check-in date. In industry practice, this typically means reservations made within a short booking window, often from a few days to a few hours before travel. Within Travel Operations & Distribution, this concept is central…

release back

Refers to the process by which unsold, pre-allocated travel inventory—such as hotel rooms, airline seats, or tour spaces—is returned by an intermediary (typically a tour operator, wholesaler, or consolidator) to the original supplier once a contractual deadline has passed. In the intricate ecosystem of Travel Operations & Distribution, this mechanism allows suppliers to regain control…

availability

Refers to the number of bookable units—such as hotel rooms, airline seats, cruise cabins, rental cars, or tour spaces—currently open for sale within a given system, date, and price category. In the realm of travel operations and distribution, it is not merely a count of remaining inventory, but a dynamic, system-governed status that determines what…

booking window

Refers to the length of time between when a traveler makes a reservation and the actual date of travel or stay. Within the operations and distribution ecosystem, this time frame is a critical metric that helps airlines, hotels, tour operators, cruise lines, and online travel agencies understand how far in advance different market segments tend…

guaranteed booking

Is a confirmed reservation in which the travel provider or intermediary formally commits to honoring the booking under the agreed conditions, regardless of subsequent availability or demand fluctuations. Within travel operations and distribution, this concept represents a crucial assurance mechanism: once space is confirmed as such—whether a hotel room, tour seat, cruise cabin, or flight…

overbooking

Refers to the deliberate practice of confirming more reservations than the actual capacity of an airline, hotel, cruise, or tour operation, based on the expectation that a certain percentage of guests will cancel or fail to show up. In the travel operations and distribution landscape, this technique is both a revenue-management tool and a logistical…
