This is my first time playing around with the aiports dlc and it was extremely fun to build this, however I am just looking for critiques from a realism standpoint, I tried to fit my passenger and cargo airports onto the same 2 runways but I ended up having cargo backups, so I gave the cargo airport its own runway, I'm just worried that the perpendicular runways are unrealistic and wonder what would be done in the real world instead?
