Online Coordination System (OCS)
-
The OCS is an online system that can provide real-time information on slot availability
at selected airports including HKIA and allow a registered user to manage its own slot
portfolio by requesting new slots or cancelling cleared slots.

Please visit the portal of the OCS at www.online-coordination.com for detailed information (including
the application procedures for creating an OCS account to become a registered user).
