British Airways is raising frequency to Bermuda and switching the service from Gatwick to Heathrow.
It will be the first time the airline has flown from Heathrow to Bermuda since 1989.
Daily flights will operate from March 28, 2021, with departures from Heathrow Terminal 5. Return fares start at £510.
The airline currently serves the island from Gatwick five times a week.
The route will be served by a Boeing 777-200, which will soon feature the airline’s new Club Suite.
BA network and alliances director Neil Chernoff said: “This is the first time we have flown to Bermuda from London’s biggest airport for over three decades.”
Bermuda transport minister Neville Tyrrell said: “We are delighted to continue our partnership with British Airways, an airline connecting Bermuda to London for more than 85 years.
“The island’s leading industry groups see clear benefits for international business and tourism as a result of this decision, which should prove pivotal in the island’s pandemic recovery.”
