For me, one of the biggest gripes of the game is the way contracts and flights work.
I have posted a similar topic on here before and I once again refer to a game called Airport Inc which I spent a lifetime playing in my childhood.
on Airport Inc you would sign a contract with an airline and that airline would have a ‘hub’ of ‘hubs’ from which they conduct their flights and said airline would fly routes from said hub to your airport and in time would propose your airport with a ‘hub request’ and would then begin to offer different routes form your airport.
At the moment flights are very random and unrealistic on ACEO and i know the devs are looking at polishing the contracts and flights section of the game.
it would also enable modders to add hubs to their airline mods to add an extra touch.
Devs, keep up the great work!
