This study examined the effects of the predictable flight schedule and the holiday schedule of airline cabin crew on their enthusiasm about a task and their leisure satisfaction. For doing this, airline cabin crew s leisure satisfaction were theoretically explored through literature review. An online survey consisting of items used in studies on 259 aircrew working for K airline was conducted. The higher the relative predictability of both duty schedule and vacation, the higher leisure satisfaction in psychological, educational, social, and relaxing aspects. Work engagement was connected with the absolute predictability of flight schedule. However, it was identified that the relative predictability of both duty schedule and vacation was important in leisure satisfaction. It implies that leisure satisfaction when duty schedule or vacation are relatively better than those of immediate supervisors and peers is higher than when fixed duty schedule or vacation are offered. This can be an opposite of the result showing the implication of leisure satisfaction is to be much more or more predictable in
psychological and emotional respects. Based on these results, it was found that strengthening communication about not only the cause for changing duty schedule and vacation, but also predicting vacation was important when airline cabin crew have a plan for vacation.
