The route will operate twice-daily Monday to Friday starting 8 March, with a single Sunday flight.

From 28 March, weekend services will increase to include a Saturday morning flight and two Sunday services.

Customers will be able to connect onto British Airways, Air France-KLM, Emirates, Turkish Airlines, United and Qatar Airways services from Heathrow through Loganair’s interline agreements.

Weekday flights, scheduled to take around 75 minutes, will depart Teesside at 6.50am and 5.55pm, with return legs departing Heathrow at 8.50am and 7.50pm.

Fares lead in from £69.99pp one-way. Frequent flyers will be able to accumulate Clan Loganair points with each journey, which can be redeemed against flight tickets.

"We’re very happy to be returning to Teesside International, and we are back for good," said Loganair chief executive Jonathan Hinkles.

"There’s no doubt air travel is having a difficult time right now, but I’m confident our plans for Teesside International are both viable, appropriate and flexible now and for the longer term."

Ben Houchen, mayor of Tees Valley, added: "Securing flights into the capital with Loganair is another feather in our airport’s cap.

"The fact that in the next few days, you will be able to go on to the websites of the likes of British Airways, Qatar Airways and United Airlines and book flights from Teesside to hundreds of destinations across the globe shows just how far we’ve come since taking the airport back into public ownership and saving it from closure less than two years ago."

Houchen added the airport was working on restoring catering and hospitality services for passengers at the airport, as well as adding my check-in desks and bolstering security in anticipation of increasing passenger numbers after the pandemic.
