A systematic literature review is used in theory-based, domain-based, method-based, metaanalytical and meta-systematic reviews (Paul et al., 2021). Elsbach and van Knippenberg (2020) proposed an integrative review (IR) as an alternative. IR synthesises literature and creates new perspectives on a topic or phenomenon (Post et al., 2020). It presents ideas founded in knowledge and identifies progress and significant gaps in the literature (Elsbach and van Knippenberg, 2020). The SPAR-4-SLR protocol was used to generate well-justified rationales following IR principles (Lim et al., 2022). It comprises three stages (assembling, arranging and assessing) and six sub-stages (identification, acquisition, organisation, purification, evaluation and reporting). 

At the assembling stage, we identified research questions and literature review domains to investigate DI discussions in H&T journals published by April 2023. The inclusion criteria are the keyword disability in conjunction with a set of industry-related keywords: (TITLE-ABS-KEY (disab*) AND TITLE-ABS-KEY (hospitality OR tourism OR travel OR food*)). Relevant publications from 2001 to 2023 were collected from two major databases (Scopus and Web of Science) with enhanced data quality (Mariani and Baggio, 2022) and reputable peer-reviewed journals (Mehraliyev et al., 2022). This chronology illustrates the evolution of DI in H&T organisations, emphasising the historical foundation and the current state of the research (Singh et al., 2023). In total, 6,098 peer-reviewed articles were collected during the assembling stage (1,229 Scopus and 4,868 Web of Science).
