For most Fleet management systems out there there is already a functionality to send the fleet schedule to Avinode.
If you want to do this, please contact the Avinode support team and we will help you set this up. This is free of charge.
What we will do is create an API token. This token needs to be implemented in your Fleet management system. (in this step you might need the assistance of your own fleet management system's support team whom can show you were to insert the token).
Once this step is done you notify Avinode and we will switch your aircraft from manual schedule updates to automatic integration. After this Avinode will mirror what you have in your own system and you will not be able to make any manual updates anymore. Depending on your settings, your schedule will be updated frequently night and day for as long as you want.
Any empty legs posted in your schedule will be automatically marketed in Avinode.
