This study aims to conduct an exploratory study in order to understand aspects of corporate sustainable activities across the flight catering supply chain at the corporate level. In order to achieve this purpose, adopting a convenient and criterion sampling strategy, 7 airlines, 3 global flight caterers and 3 global food suppliers were recruited. In addition, to improve the reliability of the data, this study has also conducted 18 in-depth interviews with the flight catering experts (for example, five airlines, three caterers, four food and three non-food suppliers and three logistics companies). As a result of these in-depth interviews, this study has demonstrated three points as follows. First, this study has found that environmental aspects include reducing emissions, conserving natural resources and waste reduction, recycling and packaging. Furthermore, as far as socially sustainable performances are concerned, whilst issues concerning people within the company are dealt with in two ways including basic human rights and welfare issues, those outside the company and their living environment relates to supporting local communities and health and safety/security issues. Second, there have been some differences in the level of adoption between the players when implementing corporate sustainable performances.
