 The closure of Kemayoran in 1985 meant that Halim would serve as the secondary airport of Jakarta, mostly handling charter flights, general aviation, and flying school base for the next 29 years.In the 1990s the Directorate General of Civil Aviation mandated that Halim would serve non-scheduled flights, as well as scheduled flights with aircraft under 100 passengers capacity.To ease congestion at Soekarno–Hatta, the Halim airport authority has announced that it will give 60 flight slots per hour for scheduled flights and, for the first time, the 2013 Haj pilgrims used this airport.
