Our DCA-MCO flights for early April were just changed. Our flight to MCO went from a non-stop evening flight to one with a stop in Nashville getting us to Orlando at 1am. I was able to change this to an earlier in the day non-stop. Our return flight moved about 90 minutes later but remained nonstop. I think it's really important if you get notification of a change to act on it ASAP before everyone else beats you to it.
