Glasgow Prestwick Airport is now in public ownership after it was bought by the Scottish Government for £1.
It is understood the deal to acquire the site from previous owner Infratil was completed late on Friday night.
Confirmation of completion of the deal comes about six weeks after the Scottish Government’s plans to acquire the South Ayrshire base, to secure its future, were announced at Holyrood by Deputy First Minister Nicola Sturgeon.
She told the Scottish Parliament at that stage that Infratil had estimated the total annual losses to be in the region of £7 million.
Announcing the development, Ms Sturgeon said: “With this deal concluded, we can now focus on the future of Glasgow Prestwick Airport and making it the success we know it can be.
“This acquisition secures continuity of service and we will now begin work, with our local partners, on developing our vision for the business so we can maximise its contribution to the local, regional and national economy.
“As we stressed at the start of this process, Glasgow Prestwick Airport remains fully open for business and existing staff remain employed at the airport.
“Senior advisory staff will be appointed on an interim basis to make recommendations on strategic business development, building on the commercial opportunities identified during the acquisition process, and on longer-term management arrangements.
“I will make a statement to Parliament in due course to set out our plans in more detail.”
