It has become my habit to check all my flights every Sunday morning. When I checked today, my return flight from SXM to CLT on Thursday 2/23 was changed from a 3:42 departure to a 5:00 departure. It still gives me 2 hours to make my connecting flight, so I am comfortable with the change.
Out of curiosity, I checked to see if by chance AA added a second flight that caused mine to be pushed back and it turns out that the only flight that day from CLT now lands at 4:40, about an hour and a half later than previously scheduled. Don't know about others, but I prefer to arrive earlier in the day to get settled.
