Each month, the actual blocked times of all airlines serving the coordinated airports are sent by the Moroccan National Airports Office (ONDA) to the coordinator.
Slot Monitoring is performed by the coordinator, comparing the allocated slots to airlines with the actually operated times in order to determine whether variations have occured.
Irregularities in relation to allocated slots are then identified and listed in three categories:
- Flight coordinated and non-operated
- Coordinated flight operated with a time significantly different from the allocated slot
- Flight operated without assigned slot
The airlines concerned are systematically informed of irregularities detected and invited to take appropriate measures to remedy this dysfunction.
