Argyle International Airport

Argyle International Airport carries the IATA code SVD — the three letters printed on boarding passes and baggage tags — and the ICAO code TVSA, used in flight plans and by air traffic control. It serves Kingstown, Saint Vincent and the Grenadines.

IATA codes are assigned by the International Air Transport Association for passenger-facing use; the four-letter ICAO code encodes region and country and belongs to the operational side of aviation.
