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
  • IATA Winter Season - starts on the last Sunday of October and ends on the last Saturday of 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
