I keep getting this erroneous notification. There's no change to the aircraft configuration that should be triggering it, and it
always says the original aircraft type is "Airbus A330-300 (333)" and new type is "333".
I've seen something
sort of like this a couple of times when creating alerts for WestJet 787 flights, where upon setup it initially detects "789". It then very quickly issues an alert that it has changed to "M89", as though it's pulling the data from two different sources where WestJet has used different codes, such that the alert is triggered even though there's no change. But in that case, it seems to settle down and stay as "M89" and not issue any more alerts.
So whether that's related, I don't know.
