This article contributes to the lack of research on refugee journeys by examining the factors influencing Afghan refugees’ plans to stay in Greece or Turkey or migrate onwards as a continuation of their fragmented refugee journeys. Following from the seminal article of BenEzer and Zetter (2015), this article examines the four conceptual challenges of refugee journeys of: temporal elements, drivers and destinations, the process of the journey, and the wayfarers characteristics. Using a quantitative approach with a unique original dataset of 364 Afghans in Greece and Turkey, regression analysis is used to examine the decision-making of Afghans to stay or migrate onwards within the context of the four conceptual challenges of refugee journeys. The results show that all the conceptual elements are significant in influencing Afghan decision-making for the continuation of their refugee journeys. The article further contextualizes these results and highlights policy implications.
