since a few days, I would think since the update to version 1.0, I have a problem with the flight planner in manual and automatic mode.
Problem is that the planner denies to place flights to international stands even when they going from Poland to Egypt and other international destinations…
Do you play in the realistic international mode or the default one? (check gameplay settings)
In the default mode, only large stands are handled as international, the destination does not matter at all.
