I booked JFK/LAX/PDX a couple of months ago. Just now, I received an email saying my trip was cancelled.

AA1 is still bookable so I know flight itself wasn’t cancelled. AA chat support doesn’t know why my reservation was cancelled. Im still on hold with them.

I guess I can rebook but why would this have happened? What if I rebook and it happens again?

If you have data points, I’m very interested to hear them. Thank you!
