Trstenik Airfield (Serbian: '''Аеродром Трстеник''', Latin: Aerodrom Trstenik) also known as "Odžaci" is a recreational aerodrome in Serbia, 2.5 km from the town of Trstenik and 12 km from the spa of Vrnjačka Banja. The airfield is within the closest vicinity (60 kilometres-about 50 minutes by Bus, instead 2 hours 45 mins from Niš Constantine the Great Airport transfer) to the famous Kopaonik mountain ski resort, and is also 20 kilometres from the Goč mountain.
The grass runway is 80abbr=offNaNabbr=off wide with concrete runway beginnings on both thresholds 30abbr=offNaNabbr=off in width and 300abbr=offNaNabbr=off in length.
In 1990, construction work came to a finish on the building of both a new control tower and underground fuel tanks.
On 4 July 1965, Jat Airways, then known as JAT Yugoslav Airlines, opened route between Belgrade and spa resort Vrnjačka Banja with a Convair CV-440 Metropolitan aircraft.
In 2007, the Vrnjačka Banja resort and the Trstenik airport requested approval for opening the airport to the public. The government will most likely accept the proposal.
