This research evaluated how rate transparency, component bundling, price, and savings of vacation packages influence online purchase decisions. Subjects chose between 12 pairs of Cancun vacation packages, one transparent (individual component pricing displayed) and one opaque (total package price only). The price and savings of the packages were systematically varied in a within-subjects design using a simulated online booking questionnaire. Price was the strongest determinant of choice, but transparent pricing increased favorable impressions of fairness and value. Transparent pricing was most effective when the pricing was different from an opaque alternative, enhancing the impact of a lower price and mitigating the impact of a higher price. There appears to be minimal benefit to transparent pricing if it is the same as an opaque alternative, and it can be detrimental if the savings is not revealed. Online travel providers can use the results to enhance their pricing strategies through the display of information.
