All Air Carriers operating to and from coordinated airports must always submit a request for the allocation of landing and/or take-off slots to the coordinator and receive approval before operating.
We advise operators to request their slots at least three business days before operation. Messages must be sent through a SCR format (Slot Clearance Request/ Response) in conformity with chapter 6 of the IATA SSIM Manual.
Dates, days and times will be strictly in UTC.
Likewise, due to apron restrictions, all requests (except those of home based operators) must be sent in transit/turnaround format using IATA aircraft subtypes only.
When a slot cannot be allocated as requested, clearance offers made by the Coordinator will be valid for three business days only. If no reply is received offer will be cancelled.
This is applicable for the submission as well as for any later modifications and cancellations.
Re-clearance of the slot on the actual day of operation should be requested only when  flight is delayed to the following day.
Allocation of slots is based on the capacity declared by the airports in which priorities are as follows:

1· Primary Criteria 

  • Historical Slots
  • Changes to Historic Slots
  • New entrants
  • Year-round services


2· Additional Criteria

  • Effective period of operation
  • Size and type of market
  • Competition
  • Curfews
  • Frequency of operation
  • Local guidelines
