Idk if you guys have a discord or not if you do what’s the code?
If you’re talking about an official Infinite Flight Discord, there isn’t one.
However, many VAs and VOs (including IFATC) use Discord as their primary communications app. If it’s a Discord environment you’re looking for that’s related to Infinite Flight, joining a VA/VO might your best bet!
Or you could go to Disboard and take a chance on some of the fan-made Discord servers.
