Scottish regional airline Loganair is to significantly increase its presence at Heathrow after shifting two important routes from Stansted and London city.
It will add services from City of Derry and Dundee after securing former flybe slots from British Airways.
In a complex deal, Loganair has agreed to a leasing arrangement of 30 weekly slots from British Airways, which had previously leased them from the closed airline flybe.
It will be the first time the the Northern Ireland airport has had a connection with Heathrow and the first time in almost 40 years for the Dundee route.
All operations will be based at Heathrow terminal two and services are expected to begin in early May. Details of schedules and pricing can be found at loganair.co.uk
