Hi! Welcome to the community! I would recommend that you check IFAE- Global Air Forces | Year of our Pilots! | Official 2022 thread, it is a virtual airline that you can join if you want to fly with other fellow military flight simmers (check their requirements to join such as grade level, flight time, etc).
Since you are new to the community, I would also recommend that you take a look at this: Guide to the Community, so that you can know all of the rules for posting, commenting, etc.
Other than that, if you ever want to do any formation flying, I am always up for a group flight! I am super active on the #screenshots-and-videos category (just started up again recently), so I would be more than happy to try out some group flights with different aircraft! If you have any questions, feel free to DM me, or any other members or regulars for assistance! Welcome again!
