This really depends on the server you’re on, and what events are happening. During an FNF, Controlling PHNL Tower on the Advanced server, I had a friend control ground, he managed at least 15 planes at any time just crossing runways, operating off of 04L and 04R for departures. Other times newer Advanced Controllers can get 4-5 planes in 10 minutes. Controlling KSAN on the Playground server will be different then controlling Oshkosh on the playground server. So it really is just what server you fly on, what time you fly at, and the experiences you have. LAX could easily be the busiest airport in Infinite Flight on the Playground Server, but if you only fly on the Advanced Server, you might say EGLC or EGBB because you’ve never experienced KLAX be busy enough to be counted here. That’s all I’m saying, have a good night!
