An expansion programme at Aberdeen Airport is expected to create as many as 1,200 new jobs.
Under the £10 million first phase of the programme, the international arrivals hall at the airport will be extended and refurbished, providing a larger terminal capacity, a larger customs and immigration hall and new baggage reclaim facilities.
A 300-metre runway extension will also be started, which will increase the range of international destinations available from Aberdeen.
The plan, which has been approved by Aberdeen City Councillors, forecasts that passenger numbers could reach four million by 2015 and 5.9 million by 2030, from three million earlier this year.
Aberdeen Airport's managing director Andy Flower told the BBC: "Our strategy is to attract more airlines and we are confident more jobs will come."
Ian Dunlop of VisitScotland said: "The ambitious plans which BAA Aberdeen Airport has set out in its master plan are very exciting for the north-east, as they can only bring huge benefits to the area and help to really put Aberdeen city and shire on the international map."
