Adria Airways and Ljubljana airport feature on a list of 15 companies and organisations to undergo privatisation as the government steps up measures to generate additional funding.
The flag-carrier is among five entities formally approved for privatisation for which procedures have already begun.
Procedures have "not yet commenced" on another 10, says the Slovenian finance ministry. These 10 include Adria's main base, Ljubljana airport, as well as its maintenance division Adria Tehnika.
The ministry says the government's approval of the draft text of a National Assembly decision clears the way for the state and various organisations - including financial holding companies, pension funds and insurance firms - to dispose of their investments.
Slovenian government measures to shore up public funds also include raising VAT from the beginning of July, the prime minister's office states.
