Can you schedule flights to airports that have not yet opened?
Said differently, Why can't we schedule flights in advance of the airport opening? Aren't arilines allowed to schedule flights in advance of the opening so that the slots are available?
You can up to (I think 1.5 months) at last 1 month though (usual procedure I do, esp. in earlier game worlds)
You just need to afford having the plane not flying for a month (or one week, if it is first seen in the scheduling display)
