 Between 1955 and 1963, the newly founded East German national airline operated under the same name but, having lost a lawsuit with the West German company, it was liquidated and replaced by Interflug.From 1926 until the outbreak of World War II in 1939, Deutsche Luft Hansa built up an extensive network centred on its base at Berlin Tempelhof Airport covering many German cities and towns, as well as the major European cities.There were early interline agreements which granted Luft Hansa passengers access to the flight network of leading European airlines of that time and vice versa.
