Shares in Norwegian were off to a flier today, after the news late on Friday that its British subsidiary had been given the go-ahead to operate flights to the US.
Shares in the airline rose as much as 6.49 per cent in Oslo during the morning.
The low-cost carrier has been waiting to receive the go-ahead from the US Department of Transportation, and announced on Friday that it had been given a permit to operate flights between the UK, Europe and the US.
Using the new traffic rights, Norwegian has announced plans for new routes to Singapore, which kicks off this week, and Argentina starting in February 2018.
With a US foreign carrier permit now received for Norwegian UK, the airline said it will be able to establish a "seamless operation" and more effectively utilise its long-haul fleet.
Norwegian boss Bjorn Kjos said on Friday: "Our Norwegian UK subsidiary has already opened the door to a range of new markets, so securing access to the US is the final piece of the jigsaw, allowing us to operate a seamless operation with affordable fares to a range of global destinations."
Norwegian currently employs over 1,000 pilots and crew at London Gatwick, and has announced plans for further growth.
It emerged last week that the airline has been recruiting dozens of Ryanair pilots, as its rival battles through the fallout of a wave of flight cancellations, saying it had messed up the planning of pilots' holidays.
Norwegian, which has been bolstering its transatlantic charge this year, said it had recruited 400 pilots since the start of the year, and 140 of those have come from rival Ryanair.
