The regional airline announced its intention last week to move the flights – currently linked to the capital via London City and Stansted – to the London hub subject to government consent.
The approval has now been received from transport secretary Mark Harper, affirming the move of Derry and Dundee services into Heathrow’s Terminal 2 from 6 May.
This will be the first ever link between Derry and Heathrow, and for Dundee, restores an air link last offered almost 40 years ago.
Loganair’s services from Kirkwall airport in the Orkney Islands and Sumburgh airport in the Shetland Islands via Dundee will also fly to Heathrow from 7 May.
Jonathan Hinkles, Loganair’s chief executive, said: "This is a milestone moment for Loganair – and indeed for regional connectivity.
"It will be revolutionary for connectivity for Derry and Dundee and the regions that the airports serve, and the benefits will be felt as far afield as Orkney and Shetland too."
