Social and regulatory pressures and competitiveness are increasingly encouraging companies to invest in diversity to manage differences in the workplace. In service industries such as hospitality, tourism, and transport, the relationships and interface between customer and service are critical (Singal, 2014). According to this approach in aviation companies, the subject of this is study, diversity management takes on even greater importance than in other industries (Steven et al., 2004). The commercial aviation industry is a high-tech service industry, extremely competitive and sensitive to the customer-employee relationship, since it is obviously a service that is consumed at the same time it is delivered (Appelbaum, Fewster, 2004). It appears known from the literature that diversity management plays a significant role in the organization’s outcomes (Lorbiecki, Jack, 2000). This study seeks, in fact, to provide a brief review of the history of diversity management in organizations, aiming to identify how, from the business side, diversity management is perceived and considered and which strategies have been implemented, or are in the planning stages, that may prove useful. In order to analyze the intangible aspects of airline and how attention to diversity can become an element of competitive advantage, a qualitative research methodology using a multiple case study was chosen in the paper, through an unstructured questionnaire interview. Specifically, direct interviews with three management figures in the aviation industry were chosen as the source of information collection. This first explanatory research confirms that the best combination of differences and, thus, the management of human resources enable the enhancement of diversity in organizations, with performance level benefits. Therefore, through the interview some strategies in aviation industry in order to sustain diversity management are highlighted. The limitation concerns the number of pilot cases observed (three) Future lines of research will be focused on the study of other company to acquire more data on the topic.
