Europe’s third-largest budget carrier, Norwegian, saw passenger numbers rise by 15% in February to more than 1.8 million.
The year-on-year rise came as the airline increased capacity by 19%. The load factor was 85.6%, up 0.8 percentage points.
Norwegian started its first routes between Paris and New York, Fort Lauderdale and Los Angeles in the month.
Chief executive, Bjørn Kjos, said: “We are very pleased that we have attracted more new business and leisure travellers this month.
“The growth is primarily due to international expansion, particularly our intercontinental operation.
“Domestic flights in Spain and the routes between the French Caribbean and the US east coast are also preforming well. Demand in the Nordic region is good and stable.”
The first of 30 new and larger Boeing 787-9 Dreamliners entered the fleet last month with four to be delivered this year.
