Calendar and Process of Coordination

 

The scheduling calendar is based, not on the civil year, but on two scheduling seasons, Summer and Winter, defined as follows:

  • IATA Summer Season - starts on the last Sunday of March and ends on the last Saturday of October (where the following Sunday is still in October)​
  • IATA Winter Season - starts on the last Sunday of October and ends on the last Saturday of March (where the following Sunday is still in March)
For each season, predetermined steps rule the process of coordination:
 
  • Distribution of SHL (Slot Historical List)
  • Submission deadline for receiving SCR
  • Distribution of SAL (Slot Allocation List)
  • IATA Scheduling Conference
  • Slot Handback  Deadline
  • Handling of Ad-hoc flights
  • Start of Season
  • End of Season
