Norwegian will look at the Boeing 787-9 as its customer base grows, says chief executive Bjorn Kjos.
"As we grow the market through low prices, as we tend to do, then it's highly likely we will look at the -9," he says at the delivery of its first 787-8 in Seattle on 27 June.
The Oslo-based carrier has eight 787s on order, which are split between five leased from International Lease Finance (ILFC) and three on its own books, including the one has taken delivery.
Norwegian has a letter of intent for three more 787-8s, Flightglobal's Ascend Online database shows.
The airline will use its 787s on flights between Oslo and Stockholm, and both Bangkok and New York from August, and between both Copenhagen and Stockholm and Fort Lauderdale from November.
"To me, it's all cost, cost, cost," says Kjos on Norwegian's long-range aircraft ordering decisions. He was referring to per passenger operating expenses.
Norwegian is unlikely to look at the newly launched 787-10. "I think the -10 will be a fantastic aircraft but we need the range to go to the Far East and, in that respect, it's highly likely that the -9 is the aircraft we would need in addition to the -8," says Kjos.
