Does "online" include games with multiplayer support?
If so, I've played FA1 through FA2.5, AH, and very briefly WB3. Also EAW MP mode and IL2~AEP MP mode.
I never liked jets as my love for aircraft stays strictly with WW2 era planes.. so I haven't played much jet sims.. and the last helicopter sim I've played was "Gunship" for DOS more than 10 years ago.

The best in the entire category of "WW2-era air combat simulation" genre, I'd have to say, is FB/AEP.
The best as a strict MMOG, is no doubt AH.
