This study aims to explore key factors affecting the individuals' perceptions on the usefulness of travel apps and sheds light on the causal paths predicting the individuals' dispositions to use them. Design/methodology/approachQuantitative data was gathered from 1,320 research participants, who were members of popular social media groups. They were analyzed through a composite-based partial least squares approach. FindingsThe results confirm that information quality, source credibility and the functionality of travel apps are significantly affecting the individuals' perceptions about their usefulness as well as their intentions to continue using them in future. They also indicate that there are highly significant indirect effects within the information technology adoption model. Research limitations/implicationsThis study integrates the information quality and source credibility factors from the information adoption model (IAM) with a functionality construct that was drawn from electronic service quality. This study examines their effects on the technology acceptance model (TAM)'s perceived usefulness and behavioral intentions. Practical implicationsThis research implies that there is scope for the travel service providers to enhance the quality and functionality of their mobile apps to improve their consumers' perceptions about the utilitarian value of these ubiquitous technologies. Originality/valueThis contribution raises awareness on the importance of incorporating a functionality construct in addition to IAM and/or TAM usability factors to better understand the individuals' dispositions to avail themselves of online content and/or to adopt interactive innovations. In this case, it implies that certain functionality features of travel apps, including their responsiveness and technical capabilities, can trigger users to increase their engagement with these mobile technologies on a habitual basis.eninfo:eu-repo/semantics/openAccessModerating RoleAdoptionInformationPurchaseWebsiteCredibilityHospitalityVariablesMediaEwomModerating RoleAdoptionInformationPurchaseWebsiteInformation qualityCredibilitySource credibilityHospitalityFunctionalityVariablesTravel appsMediaInformation technology adoption modelEwomPerceived usefulnessArticle188207214WOS:00091700350000110.1108/JHTT-12-2021-03452-s2.0-85146202582Q2Q1
