Increased long-haul carryings and holidaymakers from the UK and Europe gave low-cost carrier Norwegian Air Shuttle a boost in August.
Total passenger numbers rose by 9% to more than 2.5 million last month over August 2014.
The load factor increased by 6.1 percentage points to 89.7% with 97% of long-haul seats filled in the month.
The airline took delivery of two Boeing 737-800 aircraft in August, of a total of ten in 2015.
Norwegian also entered into an agreement to acquire two Boeing 787-9 Dreamliners in August with delivery in 2017. The carrier will have a fleet of 19 long-haul aircraft by 2018.
Chif executive, Bjørn Kjos, said: “Holidaymakers in the UK and Europe contribute positively to this month’s traffic figures.
“I’m very pleased that an increasing number of customers in the UK, Germany, Spain and the US choose Norwegian’s high quality flights at affordable fares.
“It proves that the company is even better equipped to meet the tough international competition going forward.”
Norwegian operated 99.9% of its scheduled flights in August, with 80.2% departing on time.
