Norwegian has bought 28 weekly slots at Gatwick in time for next summer.
The slots have been bought from Small Planet Airlines and will allow the low cost carrier to grow its operation from the 4.6 million passengers it currently carries to more than 30 destinations.
Norwegian chief commercial officer Thomas Ramdahl said: “London Gatwick is at the heart of our global growth ambitions so securing these crucial new slots will allow us to offer our passengers even more new routes, additional flights and affordable fares.
“Together with the launch of new routes to Argentina, Chicago and Austin in 2018, gaining extra capacity at London Gatwick is another huge boost as we get ready for our biggest ever year in the UK.”
