The growth in low-cost long-haul routes helped Norwegian boost carryings last month.
The Scandinavian budget carrier saw passenger numbers rise by 6% to almost 2.4 million in October over the same month in 2014.
The load factor increased by 6.2 percentage points to 87.8%. The load factor on long-haul routes was 96%.
The airline, which started flights from Gatwick to Puerto Rico this week, said: “Future bookings are good and the growth on long-haul routes – particularly out of London Gatwick – continues.”
Chief executive, Bjørn Kjos, said: “This month is characterised by stable growth in the Scandinavian market, not least in Norway, where many have predicted a decline in passenger demand.
“When corporations need to save cost on employee travel, they look for high quality flights at a lower fare.”
