Abstract: Techniques are provided for managing airport slot reservations using a shared database network. A computing device receives information of one or more open airport slots. The availability of the open airport slots is validated through the shared database network and is stored in a shared ledger of the shared database network. The open airport slots are published to one or more carriers to initiate electronic transactions of the open airport slots. The computing device receives one or more bid transactions from the air carriers for the open airport slots. Each bid transaction has associated bid information. The bid transactions are validated using predefined validation rules, and they are allotted to corresponding open airport slots based on the predefined validation rules and the bid information. The bid transactions allocated to the corresponding open airport slots are published to the shared ledger.
