There is a growing interest in determining the factors that influence a journal's flipping to Open Access (OA). Using semi-structured interviews combined with bibliometric indicators, this paper uncovers the perception of Spanish managers related to Open Access and the decision to flip. The key research questions are twofold: How well do bibliometric measures reflect the changes in the status of the journal? How do journal managers perceive the flipping process? In order to answer these, twelve semi-structured interviews were conducted with journal managers of Spanish Journals. The findings suggest the great majority of managers are aware of the indicators, but only two mentioned they reflect their reality. An increase in the number of submissions, visibility, or internationalization since the transition is perceived as a benefit while the loss of interchanges with other institutions is seen as the major drawback. Although flipping to OA is perceived by the managers to have many advantages, it raises some challenges too, especially the need for funding, lack of resources capacity for technical support, and the creation of alliances.
