Yes we've had it happen. We now book out of Boston because it's a direct flight. I'd call them. Especially after looking at what's available and then request to be put on another flight. They do it at no extra charge if THEY changed something.

Once they made adjustments and rescheduled us thru an airport we didn't like so I called and they made other arrangements. Another time our flight dropped off the schedule so I called to find out what had happened. Then at that time I asked if possible to be put on an earlier flight (hadn't chosen that one when I booked but now thought better of it). They said they could but at a change fee so I said you've caused me stress by dumping my rsvp so why not. And they DID change it at no charge.

Good luck!
