Scandinavian budget carrier Norwegian is ordering another 19 Boeing 787-9s, with options on a further 10 of the type.
Norwegian has previously ordered 11 787-9s through lease deals and operates a fleet of eight of the smaller 787-8.
No engine selection has been disclosed for the additional -9s but the airline’s 787 fleet is fitted with Rolls-Royce Trent 1000 powerplants.
Chief executive Bjorn Kjos says the order is “essential to further strengthening the company”, adding that its long-haul, low-cost operation has been achieving average load factors above 90%.
The airframer says the order, which it values at $5 billion at catalogue prices, is the largest single deal for the type from a European customer.
Norwegian states that the first of the newly-ordered aircraft will begin in 2017. By 2020, it adds, the airline's long-haul fleet will comprise 38 787s.
It confirms that the 344-seat jets will be placed under the ownership of its Arctic Aviation Assets division.
Norwegian's fleet modernisation also covers 100 Airbus A320neo and 100 Boeing 737 Max jets.
