Your airport can have no more than two Runways. New levels give you a chance to upgrade the Runways so that you can send any type of plane into flight. The Runway zone has two parts: Runways and bearing tracks that enable planes to move around during takeoff and landing without getting in each other’s way. If you are sending several planes into flights simultaneously, there is no need to worry: each one will take its place on a bearing track and start the voyage in its turn.
