Union Island International Airport — Union Island, Saint Vincent and the Grenadines

Union Island International Airport, coded UNI, serves the small island of Union Island in the Grenadines, part of Saint Vincent and the Grenadines in the eastern Caribbean. Despite its modest size, the airport carries international designation and accommodates flights connecting travelers to nearby islands and regional hubs, supporting the area's yachting and tourism economy. Union Island is popular among sailors and visitors heading to nearby destinations such as the Tobago Cays, a renowned marine park. The airport's short runway limits it primarily to smaller aircraft, yet UNI remains an essential link for tourism-dependent Grenadine communities, enabling quicker access than lengthy interisland ferry journeys.
