The low-cost carrier says the new seats are designed for greater comfort on longer routes and give passengers more personal space.
Norwegian was Boeing’s European launch partner for the 737 MAX last year and will take delivery of 12 of the new 189-seat aircraft in 2018, with a further 88 on order.
The first Norwegian 737 MAX to feature the new RECARO 3710C seat entered service last month.
The aircraft will service Norwegian’s transatlantic routes, replacing its older Boeing 737-800s.
It comes after Norwegian this week announced a weekly Gatwick-Tampa service while expanding a number of other transatlantic routes.
The airline also recently announced its first Canada route, flying daily to Toronto from Dublin.
