Norwegian Air achieved the greatest level of monthly passenger carryings since before the pandemic in July.
The Scandinavian airline saw 9% year-on-year growth to 2.5 million passengers – the highest number since 2019 – while regional sister carrier Wideroe flew 331,035 last month.
However, Norwegian Air’s punctuality across its fleet of 87 aircraft was down 5.6 percentage points to 67.6% over the same month last year.
This came as European air space was heavily congested with several air traffic control restrictions.
This resulted in a lower than usual punctuality across European airlines, Norwegian Group said.
The load factor increased by 0.1 percentage point from July 2023 to 92.5%, an increase of more than 8 percentage points from the previous month.
Chief executive Geir Karlsen said: “I am very pleased with the incredible job all our colleagues have been doing during the busiest travel month of the year.
“Their hard work is reflected across all our numbers, including a record high number of passengers who have chosen to travel with the group.
“For Norwegian, I am particularly pleased that we that we delivered an improved load factor versus last year while at the same time increasing capacity by 10%.
“We are excited to see a solid booking momentum for August and further into the autumn season.”
