My advice to new people or people that are bored with flying air - air only, join a squadron. Even if they aren't flying on one of more popular servers like 104th or 51st, they probably have their own mission going on. Those servers you see that are passworded are sometimes training flights for their own squadrons. Also find one that flies at the times that match yours.
I have just returned to flying after a 5 year gap. Rejoined the 51st and yes we were flying last night in a 3 ship in the 51st server. Being part of a good squadron, having Teamspeak 3 is an absolute must for online flying. Otherwise yes, I could see how it would get boring. Single ship, no TS3, lower SA. Easy target for a well coordinated squadron.
