Well airline CEO does not do a bunch of other things either what are present here, otherwise this whole game would be just nonsense if we just simulate only what a ceo does (= sits in meetings).
Read again what I wrote previously about playability. And read again the three points I wrote in the second to last message.
In real life crew scheduling for example may be computer planned initially but it is not and never can be fully automatic to the last flight. Same goes for the aircraft scheduling. There are full time staff that plan and manage those on planning (early) and operational (daily) basis (if we are talking of a normal midsize airline at least). So it is most definitely not some "elementary" thing that works like a childsplay in real life like you make it sound.
(Feel free to code or plan a program that in real time arranges your flights to nice schedules minimizing delays and maximizing utilization when you have 500 aircraft in service. ...ah, thought so... May be a bit difficult - perhaps not impossible but not worth the huge effort
