international regular flight from Ljubljana linking it to Austrian city of Klagenfurt. After WWII, the company, rebranded as JAT Yugoslav Airlines, further developed and expanded the domestic network. A major break-trouth happened in the 1960s with the creation of a regional company, Adria Airways (known until 1986 as Inex-Adria Aviopromet because of its links with the Serbian company InterExport). Initially formed in Zagreb in 1961, the airline changed its headquarters to Ljubljana in 1964 with the opening of the new Ljubljana airport. It linked, along JAT, Ljubljana with numerous domestic and international destinations, and even included, since 1965, charter flights to the United States. Also, in this period, numerous foreign companies opened regular flights to Ljubljana. Later, with the independence of Slovenia, Adria Airways became the country's flag-carrier. Air transport in Slovenia is quite limited, but has significantly grown since 1991. There are three international airports in Slovenia. Ljubljana Jože Pučnik Airport in the central part of the country is by far the busiest, with connections to many major European destinations. Around 1.4 million passengers and 15,000 to 17,000 tonnes of cargo pass through it each year. The Maribor Edvard Rusjan Airport is located in the eastern part of the country and the Portorož Airport in the western part. It has no scheduled or chartered passenger or cargo service as of 2018, but sees a lot of private flights. Adria Airways was the largest Slovenian airline until September 2019, when it declared bankruptcy and ceased all operations. Since 2003, several new carriers have entered the market, mainly low-cost airlines. The only Slovenian military airport is the Cerklje ob Krki Air Base near the Slovenia–Croatia border in the southwestern part of the country. There are also 12 public airports in Slovenia.
