Norwegian’s low-cost long-haul network saw a 56% jump in passenger carryings last month over October last year.
Europe’s third largest budget carrier achieved a long-haul load factor of 95% in the month.
Total carryings rose by 16% year-on-year to almost 2.8 million passengers with a load factor up by 0.6 percentage points to 88.4%.
Chief executive Bjorn Kjos said: “We are very pleased to see that more customers choose to fly with Norwegian and that the positive development continues in all markets.
“Our long-haul routes are more or less full, which proves that customers on both sides of the Atlantic appreciate high quality and low-fares.”
Norwegian expanded its transtlantic network from Gatwick earlier this week by starting Boeing 787 Dreamliner flights to Las Vegas.
Passengers flying with easyJet rose by almost 7% in October to more than 6.8 million.
The 6.9% year-on-year rise came as the load factor fell back by 3.1 percentage points to 90.2%.
The October figures gave the UK’s largest budget carrier a rolling annual total of 73.5 million passengers, representing a rise of 6.3% with a load factor marginally down at 91.3%.
