London City has resumed services to Danish town Billund, marking the return of business traffic from the airport.
Danish carrier Sun-Air has brought its 32-seat Dornier 328 back to the airport and will offer six weekly flights from London.
It has not flown from the airport since before the pandemic.

New flights are at “convenient flying times” and there is the opportunity for flyers to earn tier points and Avios, said the airline.
Meanwhile the airport’s biggest carrier, British Airways, will end some of its summer leisure routes and will instead add extra capacity on core business routes.
Edinburgh will increase from 30 weekly rotations in August to 46 in September and Dublin will go from 23 weekly rotations in August to 36 this month.
Anne Doyere, London City aviation director, said: “Brick by brick we’ve built back our network and we’re delighted to welcome back Sun-Air and connections to and from Billund.
“Thanks to our excellent operational performance and consistent speed and convenience, we have enjoyed a strong summer and many new passengers have had the opportunity to experience the exceptional and unique level of customer proposition that we provide at London City.
“Looking ahead, we are optimistic about the rest of the year, particularly with many of our key corporates indicating a desire to not only travel again, but travel from an airport they can rely on.”
