Hugo Cantergiani Regional Airport — Caxias Do Sul, Brazil

Hugo Cantergiani Regional Airport, identified by the code CXJ, serves Caxias do Sul, the heart of Rio Grande do Sul's wine country and a city shaped heavily by nineteenth-century Italian immigration. Vineyards blanket the surrounding Serra Gaúcha hills, and the city's grape harvest festival draws visitors eager to sample regional sparkling wines, giving the airport a steady stream of both business travelers tied to local manufacturing and tourists chasing agritourism experiences. Named for a pioneering local aviator, CXJ offers domestic connections to major Brazilian cities, functioning as a practical regional alternative to the larger airports serving Porto Alegre.
