Click on New to create a new season. (Alternatively, the user use the 'Copy' function).
The length of the season
The planning period where the schdule hasn't been published
The date when the season is published. (release of SSIM file)
Date when the season is Archived and closed for changes.
Generate IATA seasons
This option will auto generate 10 years of IATA seasonsbased on the last sunday in March and October
When the user clicks on Save, the new season is then added to the list.
The Start/End fields are the defined season period.
The Planning/Publish period fields do not have any effect on N-OC functionality. They are intended more for information purposes for the user(s).
