In the business year 2019, DFS, the German air navigation service provider, was able to increase its revenues and Group earnings, despite a slight decrease in traffic demand and an increasingly difficult external environment. In 2019, 3.334 million controlled flights were recorded in German airspace, 0.4 percent fewer than in the previous year. As a result of the corona crisis, traffic in the first quarter of 2020 decreased dramatically. At the end of March, the traffic volume in Germany was 84.7 percent below that of the previous year.
