Possibly, but it is the summer flying season and very late notice, as well as the fact that usually to my knowledge they don't have standby FAs sitting at the airport, just on call when they miss their check in time. At least this was the experience with another airline that someone I dated worked with. That said, my knowledge from this FA I know also leads me to believe that you shouldn't assume that FAs really know that much about ops as they tend not to be told much other than their own anecdotal information.
