Germanwings
Germanwings GmbH was a German low-cost airline wholly owned by Lufthansa which operated under the Eurowings brand. It was based in Cologne with hubs at Cologne Bonn Airport, Stuttgart Airport, Hamburg Airport, Berlin Tegel Airport, Munich Airport and further bases at Hannover Airport and Dortmund Airport. Germanwings operated independently as Lufthansa's low-cost carrier until October 2015, when Lufthansa decided to fully transfer the brand identity of its low cost short haul-product to Eurowings. After 2016, Germanwings operated as a wet lease operator for its sister company Eurowings, with the Germanwings branding being phased out at this time. The IATA code "4U" continued to operate under the Eurowings brand until March 2018, when it was abandoned and replaced with the Eurowings designator EW.
