This chapter explores the relationship between the transatlantic migration movement and passenger shipping conferences. By analysing records from the New York Continental Conference, which regulated prepaid and return business, it reconstructs the price brackets for major shipping firms in the final quarter of the nineteenth century. It also reveals how conferences attempted to neutralise internal and external competition. Analysis of the head agent’s correspondence offers a view of the organisation of passenger business that proves particularly insightful due to a scarcity of other contemporary sources.
