Search youtube for "Airport DLC walkthrough"

Just make sure to start a new airport, so you can see where you went wrong on the old one.

I broke my DLC airport once by using Network Multitool to change the road on the terminal building. Planes stopped spawning until I put back the original road.

Have you done anything like that?

For any hope of an accurate explanation you would need to contact someone from Colossal Order who fully understands how the DLC was designed to operate. You'd probably stand a better chance of finding out who was the second shooter on the grassy knoll.

@mistermcd once i noticed that i wasnt getting planes, i tried using i think it was more network stuff so i could se plane pathing and tried drawing it in myself but that didnt seem to fix it, so i deleted that mod. the only mods i have that can affect pathing is tmpe, transfer manager CE and more path units

Airports DLC has always been less than reliable, and building flight paths in game has always been a problem. Much better to build flight paths with Editor pre game. Either way you should always try to wait until you see planes flying overhead before you build airport, and never build airport directly under flight paths.

For these and many other reasons I prefer to use....

to set the terminals and

to build and attach the taxiways and runways.

That's me ... You do you. :)
