Norwegian Air has announced the year-round service, which will begin on June 30, 2025.
The route will provide a link for British travellers to explore Western Denmark, home to attractions such as Legoland Billund Resort.
To celebrate the new route, Legoland Billund is offering free entry for children from the UK who fly to Billund with Norwegian.
Sara Neergaard, director of communications and public affairs at Norwegian Denmark, said: “Norwegian and Billund Airport have had a strong partnership for many years, and we see great potential for growth in this region.
“With Ryanair’s recent exit, we now have a unique opportunity to strengthen our presence in Billund and Western Denmark.
“The new route to London Gatwick is just the first step, and we are continuously evaluating opportunities to expand our offerings from Billund.”
Billund Airport is located in the town of Billund, which is home to Legoland and the Lego House.
The town is also a gateway to Denmark’s west coast, small towns, and cultural and outdoor experiences.
Jan Hessellund, CEO of Billund Airport, said: “This is fantastic news – not just for Western Denmark but also for the many British travellers visiting us each year.
“With Norwegian’s new direct flights, it’s now easier than ever for UK families and business travellers to reach Billund.
“We value Norwegian’s commitment to strengthening international connectivity to our region.”
The new route is expected to be popular with both leisure and business travellers.
London is a popular city-break destination for Danish travellers, and Western Denmark is home to many large international companies.
Jennifer Newman, airlines relations manager at London Gatwick, said: “We are delighted to welcome Norwegian’s new direct year-round service connecting London Gatwick with Billund.
“This route provides essential connectivity for both business and leisure travellers, further strengthening Gatwick’s extensive European and long-haul network.”
The new route will have six weekly departures during the summer peak season.
Tickets are available now, and families flying from the UK can take advantage of Legoland Billund’s special offer of free entry for children, along with a full paying adult, for the entire 2025 season.
Terms and conditions apply.
