Flybe has stepped in to secure the vital air link between Aberdeen to London City Airport.
The regional airline will start twice daily flights on Monday, October 27 with seats from £49.99 one way.
The news has been welcomed by Prime Minister David Cameron, who had promised to help secure the route after British Airways announced it was walking away at the end of the summer.
“I welcome today’s announcement that Flybe will introduce daily flights from Aberdeen to London City later this year – a vital route that helps support the north-south economy,” he said.
“Keeping our cities connected is part of our long-term economic plan to encourage investment and promote growth so we can generate jobs, pay our way in the world, and create stability, security and a brighter future for our country.”
