I'm coming from TTD Patch and OpenTTD! I'm trying to figure out why I can't get passengers into my busses then to the airport for a flight to a neighboring city. Setting up all the hardware was easy, Road Depots, Bus Stops and Busses. Bus station at Airports too.

Airports have taxiways, runways, loading areas, Depots and terminals.

No problems getting the aircraft to fly from one to the other. The software is the problem, the people are missing! I'm using Pak128 and I don't use Lines when setting up the routes, I wonder if this might be a problem?
Thanks!
