Union Island International Airport

Union Island International Airport (TVSU) is a medium airport in Union Island, St. Vincent & Grenadines. Pilots and dispatchers reference it by ICAO code TVSU or IATA code UNI. It sits in North America.

Union Island International Airport is a regional commercial airport that doubles as a busy private-aviation base. Operators benefit from full instrument approaches and an FBO infrastructure scaled for regular jet traffic, often without the congestion of the nearest major hub.

Union Island International Airport sits near sea level at 16 ft.

Local operations run on America/St_Vincent. Scheduled airline service is light enough that it rarely interferes with charter movements, though planners should still expect to coordinate with the handling agent for international turnarounds.
