A new deal has been agreed to secure flights between London and Dundee into 2020.
Loganair will continue to operate the route between Dundee City airport and Stansted.
The UK and Scottish governments and Dundee City Council have agreed a public service obligation contract.
The airline will run 11 flights a week, with the size of the aircraft used increasing from 33 to 48 seats from next May.
UK aviation minister Paul Maynard said: “I am pleased to announce the extension of the London to Dundee route into 2020.
“This decision supports jobs and allows businesses to access global markets – as well as connecting friends and family. This is another example of how the UK Government is delivering for Dundee and the surrounding region.
“The renewal of funding is a clear demonstration of this government’s commitment to strengthen the vital ties between Scotland and the rest of the UK and our ambition for a thriving economy across the whole of the UK.”
Michael Matheson, Scottish government cabinet secretary for transport, told the BBC it would improve connectivity for Dundee and the surrounding area.
