PurposeIt is inherent in human nature to pursue a fulfilling life. The art-of-living approach provides strategies to help individuals attain higher well-being. Based on current research approaches on the art-of-living, we aimed to develop, implement and evaluate an online training that enhances art-of-living and well-being scores of flight attendants.Design/methodology/approachThe training focused on six art-of-living components – self-knowledge, savoring, bodily care, coping with events, positive attitude toward life and serenity. In total, 94 participants were randomly assigned to 3-day (n = 34) or 9-day (n = 30) training groups or to 2 corresponding control groups (CGs) (n = 30). Art-of-living and well-being were measured using self-reported questionnaires at pre-intervention, post-intervention and two-week follow-up.FindingsResults showed significant pre-post differences in art-of-living and well-being scores in both experimental groups, while scores for the CGs remained stable across assessments. Intervention effects were sustained over the two-week follow-up period. We found no significant differences in efficacy between the shorter and longer training, suggesting that brief training can be effective.Practical implicationsThese results demonstrate that well-being can be enhanced through online art-of-living training, which is promising in terms of the practical implementation of such training in resource-constrained work environments.Originality/valueThe presented, conducted and evaluated work intervention represents the first study to apply the multi-component approach of “art-of-living” in an online setting, comparing two trainings of varying durations. This approach offers a framework perfectly suited for future implementation in flight attendants’ work settings to increase well-being and a possible subsequent implementation in other professional groups that would benefit from online training (e.g. in a hybrid work context).
