Cologne Bonn Airport (German: Flughafen Köln/Bonn „Konrad Adenauer“) (IATA: CGN, ICAO: EDDK) is the international airport of Germany's fourth-largest city Cologne, and also serves Bonn, the former capital of West Germany.

[6] The airport is named after Cologne native Konrad Adenauer, the first post-war Chancellor of West Germany.

[7] The airport is located in the district of Porz and is surrounded by Wahner Heide, a nature reserve.

After World War II the British military took over and expanded the airport (as RAF Wahn - B-119).

[9] Cologne Bonn Airport was chosen by United Parcel Service (UPS) in 1986 as the location for their European hub.

Several new parking lots, a new control tower and a second terminal were built, and in 2004 a new long-distance railway station connecting the airport with InterCityExpress trains was opened.

Also, the Canadian Forces began to use the airport as a staging area to move troops and supplies in support of humanitarian missions and possible anti-terrorism roles.

Also in 2006, a daily transatlantic flight to New Jersey's Newark Liberty International Airport by Continental Airlines was established, operating with a Boeing 757-200.

[26] In December 2014, Lufthansa announced it would base Eurowings' new long-haul operations at Cologne Bonn Airport with flights to Florida, Southern Africa and the Indian Ocean to start by the end of 2015.

It features a u-shaped main building with shops, restaurants, check-in and service facilities and a visitors deck on its roof as well as the star-shaped piers B and C with five aircraft stands each plus a central airside hall between them added in 2004 with joint security-check facilities, more shops and restaurants as well as three additional stands.

As part of a plan-approval procedure the airport is currently seeking approval for building an airside connection between both terminals.

[103] The airport has its own exit (named Flughafen) on motorway A59 which links it to the city centres of Cologne and Bonn as well as the Ruhrgebiet.

[104] On 28 October 2015, a new coach terminal opened and is used for remote bus services to other German cities and many other European countries.
