Hello and welcome to the community. Great idea for wanting to make a group flight. Definitely a fun way to spend using Infinite Flight.
I have a couple of suggestions here for you and that would be to check out the Live category along with a sub category in Events. You can use these tools to create your own events here on the IFC. Another good route would be that if you are in the Official IF discord, to go there and create an event/group flight. Also do check out the Guide to the Community
These are just a couple of suggestions that’ll help get the ball rolling for you. Have a nice day!
