We‘ve been changed twice by Delta for October trip. First change was to our benefit: nonstop arriving MCO 11:35 p.m. changed to one arriving 8:15 p.m. Second change, last weekend, changed us back to the 11:35 p.m. arrival, but also changed our 8:15 a.m. return flight to 6:00 a.m. We were able up change that to a 2:45 p.m. return. Worst part is that our 7 seats were all pretty close together; best we could do was to get 3 together and then 4 together.
