The amount of the contracted rooms/seats to be specified in the allotment contract is a result of the estimated, during the negotiation, volume of sales to be realized by the
tour operator. Tour operators book a certain number of rooms in hotels or seats on carriers and have the right to use them by a given date, also known as a release date, that usually is some days prior to
tourist's arrival (hotels)/departure (carriers). The allotment contract reduces the risk of any unsold products by the supplier and grants relative price advantage to the travel organizer helping him to stay competitive on the market by offering extra
discounts. Tour operators obtain discounts, through allotment or commitment contracts, primarily depend on the firm size and the bargaining power exercised; they can vary from 10% to 50% according to the period of the year, the destination, the quantity and quality of services contracted upon. Some big tour operators are able to obtain up to 70% of discount. ==References==
