Online Coordination System (OCS)

The Online Coordination System platform provides online access to live airport slots databases and allows users to edit their slots online. Access rights to airports are granted by the coordinators and are separate from other administration services provided by third parties (e.g. account creation). More information and registration instructions can be found on:

Processing of requests through OCS is automated and subject to coordination parameters and rules governing the slot allocation process. All processed requests are monitored by HSCA.

Misuse or abuse of automation and coordination procedures may result in suspension of access through the OCS platform.
