Some 274,000 more passengers travelled on Norwegian’s flights in July compared to the corresponding month last year.
Over 1.3 million customers flew with the airline over the course of the month, which represents an increase of 26 percent from July 2009. It is the third month in succession that Norwegian has set a passenger record.
Bjorn Kjos, Norwegian’s chief executive officer, said he is "very pleased with the great boost" in July’s traffic figures.
"The airline industry has been facing turbulent times recently due to the closing of European airspace and third party strikes," he explained.
"However, the heavy passenger growth proves that our customers are confident that Norwegian and the airline industry in general are back on track."
Despite the passenger increase, Norwegian recorded a load factor of 85 percent, which is a three percent decline from July last year.
The airline is Europe’s fourth-largest cheap flights carrier having accommodated more than 9.1 million passengers in 2008.
