Day Air Credit Union was founded in 1945, by 26 employees of the United States Air Force Depot – Gentile Station (later known as DESC); who came together as a group to help each other improve their individual financial situations. After much discussion, the original members decided to combine the words “Dayton” and “Air Force” creating the name we know, “Day Air.” To date, Day Air’s field of membership includes anyone who lives, works, worships or attends school in Montgomery, Greene, Warren, Butler, Clark, Champaign, Darke, Preble, and Miami Counties.
