I think there should be an option for an ATC to tell an aircraft to divert to a close airport due to weather or it is over capacity. This could be a thing for advanced only so it isn’t over used.
We have an airport is full message
It would be cool if you could only do it when you need it (e.g. If it’s really windy)
Message is only available for to we r at the moment, and we don’t have any way to notify what kind of delay there is, or if it is reopening…
