Cologne Bonn Airport

Cologne/Bonn is the airport where you see three completely different worlds on a single day. At midday, Eurowings jets and leisure aircraft taxi to the main runway; in the evening, the big freighters of UPS and FedEx float in; and in the west of the grounds stand the gray government jets of the Flugbereitschaft. CGN is not a connecting hub like Frankfurt or Munich – but for spotters, this very mix is the appeal.

From air base to 24-hour airport

The roots of the airport are military. In 1938, the Luftwaffe built an air base on the training area in the Wahner Heide. After the war, civil traffic began on a small scale around 1950, a first international scheduled connection started in early 1951, and in 1957 a civil administration took over the site. With the main runway, which went into operation in 1961, the jets arrived – and because Bonn was the capital, Cologne/Bonn became the government airport of the Federal Republic. State guests landed here, including US President John F. Kennedy in 1963.

In 1970, Terminal 1 opened, designed by the architect Paul Schneider-Esleben: a building of exposed concrete with two star-shaped piers that still shape the look today. Since 1994 the airport has borne the name of the first Federal Chancellor, Konrad Adenauer, though in everyday speech almost everyone simply says “Köln/Bonn” or “CGN”. A spectacular moment for aviation fans was the 1983 visit of the Space Shuttle Enterprise, which landed on the back of its carrier aircraft and attracted numerous onlookers.

The real turning point came in 1986, when UPS made Cologne/Bonn its hub in Europe. Since then, the airport has been above all one thing: a cargo location that also works at night.

Three runways, new numbers

Cologne/Bonn has a runway system that is unusual by German standards. The main runway 13L/31R is 3,815 meters long and carries most of the traffic – from the A320 to the fully loaded 747-8F. To the west alongside it lies the short parallel runway 13R/31L at 1,863 meters, close to the military area. To the north, the crosswind runway 06/24 at 2,459 meters crosses, used depending on the wind situation.

Important if you read older photos or spotter guides: until April 18, 2024, the parallel runways were called 14L/32R and 14R/32L. Because the Earth’s magnetic field is shifting and runways are named after their magnetic heading, they were renumbered. The crosswind runway remained unchanged. The logic behind it is explained in the post on Runway designations at airports.

Runway direction: 31 or 13?

Aircraft take off and land into the wind. With the westerly weather patterns common in Germany, operations in Cologne/Bonn therefore tend toward the northwest, that is, on 31 or, with suitable wind, on 24. If the wind turns east, takeoffs and landings are on 13 or 06.

For you, this has direct consequences. The observation deck plays to its strengths with landings on 13L, because aircraft then taxi toward the terminal after touchdown. If they land on 31R, that happens far to the southeast of the airport – then the fence spots at the south end are the better choice. How to assess wind and runway direction before heading out is covered in the post Understanding runway direction at airports, and you can check it live with flight tracking via ADS-B.

Cargo: the real heart of CGN

By passengers, Cologne/Bonn is number six in Germany, by cargo number three. In 2025, a good 842,000 tonnes were handled – most of it in dedicated freighters, not in the bellies of passenger jets. The absence of a general night curfew makes it possible: express services need exactly the hours when it’s quiet elsewhere.

UPS Airlines has operated its most important hub in Europe here since the 1980s. In the evening you see the brown jets in series – including the Boeing 747-8F, the freighter version of the 767 and the 757F. FedEx Express has used Cologne/Bonn as a hub for Central and Eastern Europe since 2010 and sends, among others, the Boeing 777F. DHL is also represented with a logistics center at the airport.

A special case is the McDonnell Douglas MD-11, which was part of everyday life in Cologne for a long time. After the crash of a UPS freighter in November 2025 and the grounding that followed, UPS permanently retired the type in early 2026. Since the grounding was lifted in May 2026, FedEx has been bringing its aircraft back step by step. As of October 2026, an MD-11 in Cologne is a matter of luck.

Passenger traffic: Eurowings, Turkey and leisure aircraft

In passenger traffic, Cologne/Bonn is a classic point-to-point airport. The picture is shaped by Eurowings, the low-cost airline of the Lufthansa Group, which has aircraft based here. It flies mainly the Airbus A320, the A321 and the A319. The history of the location is closely tied to the group: until 2014, Cologne/Bonn was the home of Lufthansa CityLine, until 2020 of Germanwings, and from 2015 to 2018 Eurowings long-haul even took off from here – before it moved to Düsseldorf.

Add low-cost carriers like Ryanair with the Boeing 737-800 and the 737 MAX 8. A strong block is Turkey traffic, driven by the large Turkish community in the Rhineland: Pegasus, SunExpress, Turkish Airlines and Corendon are seen considerably more often in summer than in winter. Depending on the season, other leisure airlines are added.

Scheduled long-haul passenger flights have not existed since the withdrawal of Eurowings long-haul. One event stays in spotters’ memories nonetheless: in September 2009, an Airbus A380 landed in Cologne/Bonn for the first time.

Government aircraft and military

A unique feature is the military section in the west of the grounds. The Flugbereitschaft of the Ministry of Defense has been at home here since 1959. On its apron, depending on the day, stand government jets such as the Airbus A350-900, aircraft of the A320 family or business jets. Since 2020, a multinational NATO unit with tanker aircraft based on the A330 has also used the airport, and the Canadian armed forces have a logistics base here too.

For spotters, this is a stroke of luck – but one with an expiry date. In the long term, the Flugbereitschaft is planned to move to the government terminal at Berlin Brandenburg Airport; 2032 is named as the target year. Until then, the aircraft often fly empty from Cologne to Berlin to pick up passengers there. How to plan specifically for government aircraft is explained in the post Spotting government aircraft.

Spotting in Cologne/Bonn

The easiest way in is the observation deck on the roof of Terminal 1. It is free and lies outside the security area, so you need neither a boarding pass nor screening. From above, you look across the Terminal 1 apron to the main runway and west to the military apron. According to reports from the spotter scene, there is an upper, open level without glass – ideal for photography. All details on access, focal length and light are in the spot guide to the observation deck at Cologne Bonn Airport.

If you want to get closer to the runways, you’ll find numerous fence spots and elevated parking decks around the airport. Many of them are in the Wahner Heide, where leaving the paths is prohibited in some sections. Respect that, don’t lean ladders against the fence and don’t block access roads. You’ll find the general rules of the game in the post Is plane spotting allowed?, and drones stay on the ground in the airport’s control zone anyway – more on that under Drones at airports.

Night, light and season

Because there is no general night flight ban, Cologne/Bonn is one of the few German airports where operations continue after 10 p.m. For photographers, that opens a discipline of its own: taxi traffic with position lights, freighters in the floodlights of the aprons and long exposures of takeoffs. How to do this technically is covered in the post Photographing aircraft at night. The rules of other airports in comparison are summarized in Night flight bans at German airports.

In summer, the passenger and cargo waves merge: leisure aircraft in the afternoon, first freighters in the evening light. In winter it gets harder – then cargo movements are almost entirely in the dark, and Turkey and leisure traffic is thinned out. On hot days, heat haze over the large apron makes distant aircraft go soft; concentrate then on aircraft taxiing by up close.

Cologne/Bonn compared

In the Rhineland, Düsseldorf Airport is the bigger neighbor with more passengers and long-haul; there you have the observation deck at Düsseldorf Airport at your disposal. For long-haul in series, there is no way around Frankfurt Airport, which is quickly reachable from Cologne/Bonn by ICE.

If you like the cargo in Cologne, also take a look at Leipzig/Halle Airport: DHL operates its large European hub there, and the observation deck at Leipzig/Halle is the fitting counterpart to CGN. For a trip to the neighboring country, Brussels Airport is an option. A bigger overview is given by the list of the best spotting spots in Germany, and if you’re brand new, Plane spotting for beginners helps.

Conclusion

Cologne Bonn Airport is no place for long-haul passenger jets, but one of Germany’s most versatile airports. Eurowings and Turkey traffic fill the day, UPS and FedEx the evenings and nights, and on the military apron the Flugbereitschaft waits with a fleet you won’t see anywhere else in Germany – at least as long as it is still stationed in Cologne.

With a train station under the terminals and a free rooftop deck, getting started is as easy as it gets. What makes the difference are runway direction, time of day and season: anyone who arrives at midday in summer, hopes for landings on 13L and stays until the evening takes more away from Cologne/Bonn than from many a bigger airport.
