Budget airline Norwegian is raising premium class capacity on long-haul routes.
The expanded premium cabin on new Boeing 787 Dreamliners will have 60% more seats
The 56-seat cabin configuration will offer passengers more than a metre of legroom and 11 inch Panasonic monitors providing free in-flight entertainment.
The new cabin will be fitted on 20 Dreamliners set for delivery from February.
Ten out of 11 new aircraft to be added to the airline’s long-haul fleet from Gatwick will feature the new premium cabin.
Twelve new Boeing 737 MAX aircraft will join the fleet this year to serve the carrier’s transatlantic routes from Edinburgh, Belfast and Ireland to the US east coast.
Norwegian will begin to expand in-flight wi-fi on long-haul routes at an unspecified date later in the year.
The number of transatlantic flights from Gatwick will see Boston gain a daily service up from increases from five flights a week with fares starting at £134.90 one way.
The airline also plans to increase Oakland-San Francisco frequency to a daily service.
More flights are planned to Los Angeles, with twice-daily departures on selected days of the week.
Norwegian’s first route to South America starts on February 14 with flights from Gatwick to Buenos Aires available from £299 one way.
Four Dreamliner flights a week are scheduled to Argentina.
This will be followed on March 25 with a new daily route to Chicago from £149 one way and to Austin, Texas, three times a week from March 27 with single fares starting at £164.90.
Chief commercial officer Thomas Ramdahl said: “This year will see us fly to new heights as the UK will continue to be centre stage for our international growth.
“We want to fly people further for the best possible value which is why we’re investing for the future in low-cost long-haul travel.
“We’re upgrading the long-haul passenger experience by introducing a bigger premium cabin, inflight wi-fi and more brand-new aircraft to service our expanding network.
“It has never been a better time to fly Norwegian and we’re excited to launch affordable flights from London to Argentina where we have active plans to take-off this year.”
