Since the governments of Chile, Colombia, Mexico, and Peru inaugurated a new Latin American integration mechanism, the Pacific Alliance, in 2011, the bloc has recorded both encouraging and disappointing results, depending on the evolution of the Alliance's main five aspects-political, economic, institutional, cooperative, and societal linkages. Although economic integration did not advance at the expected pace, owing to the abolition of a Mexican visa for Peru and Colombia, between 2011 and 2019, there has been a significant increase in social exchanges of nationals of the four countries, which included activities such as tourism, education, business trips, and others of similar nature (the Pacific Alliance's fifth element). Yet, despite these developments, scholars did not attempt to examine the societal linkage within the bloc, referred to in this article as the "fifth element" of the Pacific Alliance. To narrow the gap, this article examines the path of the Alliance toward deep integration by identifying the effect of strengthening social interactions, using a transnationalist framework and paying particular attention to the changing patterns of individual trips over more than 10 years of the Alliance's existence.
