German reunification led to significant changes to the European aviation market, and in particular in Berlin: German airlines now gained access to the city. In 1991, Air Berlin (which had 90 employees at the time) was restructured as Air Berlin GmbH & Co. Luftverkehrs KG, a German-registered company, with several German investors joining Kim Lundgren, the original founder, thereby bringing the ownership in line with German foreign-control requirements. Joachim Hunold (de), a former sales and marketing director with LTU International, now led the company.
