Wonderful, I think that would do nicely. However, it tells me
"As defined, more than 1,000 flights a week will trigger this alert.
To enable high-volume alerts, please contact us to learn about Enterprise accounts."
Of course if truly filtered on diverted, this error is incorrect and now I need to ask, how to bypass this error? I'll see if there is a way to contact support.
What airport were you using?
