This paper adds to a growing body of literature which views global citizenship education as part of a broader social and cultural process of subjectivity production. Rather than focus on global citizenship in relation to pedagogy or curriculum content, as much of the previous research literature has done, this paper examines it in relation to the practice of travel. Drawing on data generated in ethnographic fieldwork in two UK schools, the paper explores the way in which the young people in these settings used travel to position themselves as successful, mobile, global citizen subjects. The paper argues that these subjectivities were negotiated as part of a dynamic process: one which took place across multiple spaces, in a myriad of different relationships, and in the deployment of a number of different power relations. The paper concludes with some thoughts about the practice of school travel and how it might effectively be focused upon in future research.
