1. A computer-implemented method for presenting rates for travel services, the method, as implemented by one or more computing devices, comprising: obtaining a dynamic range of available rates for a travel service over a selected date range; subdividing the dynamic range of available rates into a plurality of pricing bands, wherein each of the plurality of pricing bands represents a portion of the dynamic range of available rates; determining an approximate rate for the travel service based at least in part on a pricing band, of the plurality of pricing bands, within which an exact rate for the travel service on a first date of the selected date range falls; and causing, in an interactive interface, presentation of the approximate rate for the travel service using a characteristic associated with the pricing band, the approximate rate presented concurrently with an additional approximate rate for the travel service on one or more alternative dates of the selected date range, the additional approximate rate presented using a second characteristic associated with a second pricing band of the plurality of pricing bands.
