It is located near the village of Sečovlje, 6 km (3.7 mi) south of Portorož, and less than 300 m (980 ft) from the Croatian border.

In addition to Portorož, the airport serves a number of other tourist destinations in the region, including Piran, Izola, Koper in Slovenia, Trieste in Italy and Umag in Croatia.

The airport is intended for passenger and cargo transport, sport, tourist and business flights.

In 1962, ground preparations were initially made for the creation of a sports airport with a 400 m (1,300 ft) grass runway.

The following year, 12 February 1973, the ZUCZP granted permission to register and license Portorož Airport for aviation sports purposes.

Upgrades to the airport continued and, in the same year, a fueling station, which supplies Avgas 100LL, was built.

Also in 1981, the airport facilities were further expanded and included the construction of a control tower, border crossing, meteo and FIO.

On 20 March 1986, construction work was completed on a technical aircraft hangar and airport fire station.

As a consequence, on 21 March 1989, the Federal Secretary for Transport and Communication issued a permit, which allowed night operations.

Furthermore, a permit was issued for take-offs and landings of aircraft with a maximum weight of 27 tonnes (54,900 lbs.).

Investment in Portorož Airport continued and, on 15 April 1991, the Casino Touristic Company Turistično podjetje p.o.
