Airport expansion

[stattohogg2020]

Question for those with more experience than I, is it quite predictable when an airport will expand? Or fairly variable?

I assume when 99% of slots are filled, it can't be far away, suely. Please?!

Also - a feature suggestion for Sami - resale of slots like in the real world! :-)

Generally you can rely on historical events to happen around the same time they did in real life but certain things like the arrival of particular aircraft models is randomized within reason. Airport replacements are definitely included and your flights will move automatically in that event. However I've never considered expansions as I tend to avoid the big time airports.

The airport expansions will happen based on how busy / occupied the airport is, but also randomly for smaller airports.

There's a threshold on slot occupancy which after the airport becomes a potential candidate for the expansion, but don't have the figures right here. There is also a limit of how quickly after previous expansion it can re-expand, and limits on how much these can happen worldwide.
