[Suggestion] Link real-life events/rules to in-game
The first part of my suggestion is similar to suggestion issue #245, which proposed big events increasing demand. Here I suggest that the irl events may be linked to in-game demand, or even things like airport closure in-game. For example, freak natural events such as Hurricane Florence and Super Typhoon Mangkhuy would lead to airport closure and rerouting of certain flights to avoid the storm. This would force the airlines to cancel flights to the affected areas, and even reduce demand in the days and weeks after the typhoon.
Another part of the suggestion will be to look at irl rules and regulations and how it affects flights, especially after the implementation of political restrictions. For example, flights are not allowed between China and Taiwan, or India and Pakistan, without prior agreement from the governments (or China authorities in the former's case). These would make the airline route planning more realistic (like there won't be international flights into DCA from Madrid or Paris when the airport has no customs)
