Long ago I played this game called Airport Mania.
In it you’re an ATC. There’s like 10 stages (airports), with several levels in each stage in increasing difficulty. There are different capabilities to add to the airport (such as de-icing, defogging, upgraded terminals, upgraded fuel pumps, layover spaces, additional runways etc). Different types of planes had different patience levels (for example, Concordes needed quick service) etc. Very sophisticated. It was fun.
About 5 years ago a slightly watered down version of it was available on Android. I think it’s gone now. Even as an adult I found it engaging. It may look childish in the screenshots but it’s really fun.
It’s the only game I have bought online. They sent me the CD from Portland Oregon to my home on the opposite side of the Earth.
