Norwegian Air Shuttle will configure its Boeing 787 aircraft with 291 seats, with 259 in the economy-class cabin and 32 in premium-class.
The low-cost carrier plans to take delivery of its first Dreamliner in April next year as it launches long-haul services from late May to New York and Bangkok from Oslo and Stockholm.
All-leather Timco-supplied seats will be fitted throughout the aircraft. The economy-class seats will have a pitch of 31in (79cm) and those in the premium-class cabin will have a pitch of 46in.
Norwegian is recruiting staff from Bangkok to serve both new destinations and says the "hiring process is well underway".
It plans to have a total of 23 pilots and 70 cabin crew for each 787, says Norwegian, with training for flight crew already under way.
As part of the carrier's livery it displays images of famous Scandinavians on the vertical stabilizer of each aircraft. It says that figure skater and film star Sonja Henje will appear on its first Dreamliner.
