The airline said net profit for the period was 435.9 million Norwegian kroner ($74 million), compared with 628 million kroner a year earlier. It said it spent just over 100 million kroner on replacing the 787s, dubbed Dreamliners, and compensating delayed passengers.
Third-quarter sales rose 15 percent to 4.88 billion kroner from 4.22 billion in the same period 2012.
