In ICAO (International Civil Aviation Organisation) Europe Region, the ATFCM (Air Traffic Flow and Capacity Management) is managed by EUROCONTROL (European Organisation for the Safety of Air Navigation) for a long time. Planned ATFCM applications on nowadays and future time periods are not well enough to solve the airport congestion in an effective way. In the present case, main purpose of this study is to give alternative solution suggestions for narrow airport capacity and to ease the parking positions by making new departure time offers to the airline operators. In the scope of this study, to create free parking positions in every hour zone, air traffic flows are arranged from the imaginary airports to the target arrival airport in the MS Office Excel programme. The possible advantages and disadvantages of this study are discussed in the result section.
