Debrecen International Airport — Debrecen, Hungary

Hungary's second-largest city relies on DEB for air links that bypass a lengthy road or rail trip to Budapest, making the airport an alternative gateway to the country's eastern Great Plain region. Debrecen carries deep historical weight as a center of Hungarian Protestantism and briefly served as the nation's provisional capital during a turbulent period in the twentieth century. Low-cost carriers, including a Wizz Air base established at the field, have expanded route networks in recent years, connecting the city to Western European labor markets and to visitors drawn by the region's thermal spas. DEB underwent modernization to accommodate this growth, upgrading facilities that once served far fewer passengers. Cargo operations and flight training round out the airport's modest but steadily growing role.
