It is possible to integrate operators with 3rd party vendors through Leon, like: Avinode, PrivateFly, Jettogether, or StrataJet.
The advantage of being integrated with these softwares is that your flights will be available to brokers worldwide. In order to integrate your system please contact Leon support at email@example.com.
Once you have been integrated with some 3rd party vendors you can find the settings in section Sales > Schedule Export.
On the screen (tab General) you can see columns representing particular vendors, where you can define what aircraft should be integrated (mark chackboxes and save settings).
