Lufthansa CityLine GmbH is a German airline with its headquarters on the grounds of Munich Airport.^[2][3] It is a wholly owned subsidiary of Lufthansa and maintains hubs at Frankfurt Airport and Munich Airport,^[4] from where it operates a dense domestic and European network as a member of Lufthansa Regional.

The airline's corporate headquarters are at the Flight Operations Center (FOC) at Munich Airport.^[2] In May 2013 it was announced that the management and administration offices of CityLine would be relocated from Cologne to Munich.^[15][16] The move was completed as of September 2014.^[2]

The airline was previously headquartered at Cologne Bonn Airport.^[17] In 1998 the airline moved its offices to the security area of that airport; several of its departments however were in Munich. In 2009 the airline moved its head office into the former Cologne/Bonn Airport administrative building.^[15]

• On 6 January 1993, Lufthansa Flight 5634 from Bremen to Paris, which was carried out under the Lufthansa CityLine brand using a Contact Air Dash 8-300 (registered D-BEAT), hit the ground 1800 metres short of the runway of Paris-Charles de Gaulle Airport, resulting in the death of four out of the 23 passengers on board. The four crew members survived. The accident occurred after the pilot had to abort the final approach to the airport because the runway had been closed due to the aircraft ahead, a Korean Air Boeing 747, suffering a blown tire upon landing.^[25]
• On 28 December 1999, a passenger on board Lufthansa Flight 5293 from Prague to Düsseldorf, which was operated by Lufthansa CityLine using a Bombardier CRJ100 aircraft (registered D-ACJA), claimed to have a bomb on board and demanded the flight be diverted to the United Kingdom. The pilots convinced him to have a fuel stop at Düsseldorf Airport, where all passengers left the plane (many of them unaware of the hijacking attempt), and the perpetrator was arrested.^[26]
• On 5 July 2014, Lufthansa Flight 1360 from Frankfurt to Katowice, operated by Lufthansa CityLine using a Bombardier CRJ700 aircraft (registered D-ACPJ), landed on an unopened and under construction runway at Katowice Airport. The pilots performed a normal approach from the East in good conditions and visibility before landing on the closed runway. No one was hurt, and the aircraft later made a technical flight to land on the correct runway. The Polish State Commission on Aircraft Accidents Investigation made recommendations to add additional markings to the runway (in the form of red X shapes on the runway), and to modify the ATIS to include warnings about the closed runway. The CAT I ILS was disabled due to the construction, and the aircraft featured an older EGPWS that lacked a "Smart Landing" mode and high resolution map of the area which prevented it from informing the crew of the situation. During the approach, PAPI and threshold lights were set to maximum brightness. The incident is still being investigated by Polish authorities.^[27]
