In 1992 a system of self-financing replaced the previous method of financing by means of air navigation fees and directly from the federal budget. As is internationally common, since 1st January 1993 the expenses for airport coordination were covered by the airspace users, that is to say, the airlines.
Since January 2013 the airlines, owners of aircraft with a German registration and the coordinated and schedule facilitated German airports share the annual costs. Every year the Federal Ministry of Transport and Digital Infrastructure determines the cost unit rate per slot which the airport coordination then charges to the users according to the amount of their requested slots.
In order to ensure the economic basis as well as transparency, an airport coordination interest group advises the Airport Coordinator and the Ministry. Members are representatives from German airlines as well as BARIG, representing the active airlines on the German market, representatives for general aviation operators and since 2013 representatives from the German airports.
