Why no cancellation notification

Hi-

I put in a notification for this flight:

flightaware.com/live/flight/UAL5 … /KSFO/KPHX

and it was cancelled according to google, etc.

flightstats.com/go/FlightSta … aign=co-op

Why didn’t flightaware pick this up?

It will eventually drop off. As far as I know there is no “cancel” in the status field - just scheduled, diverted, and enroute

Not sure what you mean.

In the notification alerts the following events are listed

Alert Events

FlightAware will send you an alert when any of the selected events occur:
Flight Plan Filed:
Departure (wheels-up):
Arrival:
Cancelled:
Diverted:

What is the point of the “Cancelled:” alert if it doesn’t fire when a flight is cancelled?

Our cancellation alerts only apply to flights that have already departed.
