Increasing numbers of long-haul and business passengers helped push September carryings by budget carrier Norwegian up to almost 3.5 million.
This represented a rise of nine per cent or 281,823 passengers over the same month last year.
The increase came as capacity went up by 32% year-on-year.
Europe’s third largest budget carrier achieved an overall load factor of 88.6% with long haul flights at 92.4%.
While yield was reported as positive, the airline was negatively affected by a new Swedish passenger tax and because it operated more longer flights than the same time in 2017.
As the revenue per passenger kilometre is lower on longer flights, the company’s total yield falls as the share of long-haul flights increases, according to Norwegian.
The airline was last month named as the most fuel-efficient carrier on transatlantic routes for the second time by the International Council on Clean Transportation.
Norwegian CEO Bjorn Kjos said: “We are very pleased that an increasing number of passengers choose Norwegian for their travels, especially business passengers.
“I’d particularly like to point out our long-haul routes where the demand is high and continues to increase.
“The recognition from ICCT is truly the highest form of industry praise and proves that our investment in brand new planes reduce our environmental footprint.
“New aircraft is win-win for our customers, the environment and the company.”
The airline took delivery of two Boeing 737 MAX 8 and one Boeing 787-9 Dreamliner in the month.
Norwegian will take delivery of 11 Boeing 787-9s,12 Boeing 737 MAX 8s and two Boeing 737-800s this year.
