The 2,339,515 passengers who used the airport last month represented the highest ever number of September travellers ever and a 6.4 percent increase over September 2013.
It also marked the 18th month in a row that the airport set a monthly passenger record.
“If we look to our main competitors, the other European hub airports, we remain in a very comfortable position in terms of growth this year. Our stable traffic growth throughout the summer programme is part of the reason that we have been able to secure one of the highest growth rates in Europe,” Thomas Woldbye, the CEO of Copenhagen Airport, said in a statement.
The airport reported that international traffic was up 6.7 percent in September and domestic traffic was up 3.4 percent. Transfer traffic increased by a full 14.5 percent.
“The major part of the intercontinental traffic out of our region still departs from Copenhagen, and the solid transfer growth therefore strengthens our hub,” Woldbye said.
Through the first nine months of 2014, over 19.7 million passengers have travelled through Copenhagen Airport, a 7.1 percent jump over the same period last year.
In June 2014, Copenhagen Airport had its busiest month ever but that record was toppled the very next month when 2.6 million passengers used the airport in July.
