Work will see a 50% increase in the size of the terminal building and a comprehensive transformation of current passenger facilities.

The first phase of what will be a three year project will get underway in May 2016.

This will involve the construction of a two-storey extension to the south of the existing terminal building.

At ground level, the extension will accommodate all facilities for international arriving passengers as well as domestic baggage reclaim. Two business lounges will be located on the upper level.

Carol Benzie, Managing Director of Aberdeen International Airport, said: “Not only does this investment represent the most significant upgrade to the airport since the current terminal first opened in 1977, it demonstrates our commitment to providing passengers with high quality facilities.

“We have long recognised the need to expand the terminal and we are doing so with the long term future of the airport in mind.

“It is one of the most important pieces of transport infrastructure in the North East of Scotland and it plays a crucial role in supporting the wider economy.

“Now more than ever, it is vital that we invest in our airport to help improve the region’s attractiveness as a key investment destination and that we provide passengers, airlines and the city with an airport they can all be proud of.”
