Copenhagen International Airport (CPH) celebrated a historic milestone in September 2025, when it counted 3.1 million passengers passing through its gates. The number, which signals a 9% increase compared to the same month of last year, also marks the busiest month in the airport's 100-year history.
The impressive figure highlights the high demand for flights during the transition season while proving Copenhagen's growing status as a global transportation hub.
The most notable trend is the rise in transit flights, where the airline recorded a 35% boost in passengers who chose to opt for connecting flights via Copenhagen compared to last September. Many of the travelers originated from Norway, Sweden, and Finland.
The average load factor for incoming and outgoing flights reached 80%, a level never recorded in autumn. Airlines are addressing the rising demand with more efficient and economical aircraft, including Airbus A320neo and Boeing 737 MAX, which now represent about 37% of the active fleet at the airport, compared to just 5% in 2019.
The shift to new models will also reduce noise and pollution, bringing a significant advantage for an airport situated in the heart of a dense European capital.
Despite the impressive achievements, September also presented challenges, as drone incursions into the airport's airspace led to delays and flight cancellations. These incidents once again underscored the increased need for close cooperation among airport management, authorities, and airlines to facilitate effective risk management.
Forecasts indicate a continuation of positive momentum into the fall and upcoming holiday season. On certain days, up to 115,000 passengers are expected, with the bulk of the traffic stemming from short city tourism and weekend flights to popular destinations across Europe.
