[HELP] How to increase the number of planes landing at the airport?

[Dqiaowei]

In the map of Prague airport, I have 5 landing sites as shown in the picture (4S,1M). But the maximum number of planes landing is only 3. I noticed that when there are 2 S planes and 1 M airplane at the airport, the game immediately says “no arrivals available”. The question is how can I increase the number of planes at the airport?
Thank you.

You need in NPC airport’s open more arrivals slot’s by money or by servicing plane from those destination. Like on picture, you can see that I can receive 11 different plane from 1 destination.
