Norwegian Air carryings declined by two percent in November to 1.3 million passengers.
The Scandinavian airline described the year-on-year reduction as being in line with “significantly reduced” capacity of six per cent to match the winter low season.
An average of 66 aircraft were operated last month with a high level of punctuality.
While Christmas and the new year will be a busy travel period in line with expectations, Norwegian Air said it was “well positioned navigate the quieter winter trading season”.
In addition to capacity adjustments, the airline is “comfortably hedged” for jet fuel at “attractive prices” for the coming year.
The airline is to operate 40 routes to new destinations as part of its recently released summer 2024 schedule
Chief executive Geir Karlsen said: “Norwegian has delivered very solid traffic numbers in a month where seasonal demand is normally at a low point.
“We have adjusted our capacity considerably to meet the fluctuating demand in the winter, and we are particularly satisfied with our strong load factor of 82.3%, up three percentage points from November last year.
“Additionally, we have delivered an outstanding performance when it comes to regularity with close to all of our almost 10,000 flights taking place in November.”
He added: “We continue to see strong demand for air travel. Many of our customers took advantage of our latest sales campaign to book their next journeys.
“Our newly launched summer programme has been well received, and we notice that travellers have already started to plan their flights for 2024, earlier than last year.”
