I just checked my flights this am and the flight MCO to BOS is showing up again but only showing first class availability and times are changed again by 5 min. I went to my itinerary and no changes had been made to that but when I checked to see how full the plane was the plane had been changed again and didn't list my seats. I called Delta and they still had me listed with the old seats and said all the changes hadn't shown up in the system yet. He said they automatically reassign the seats when they change the planes. I'll just have to keep chcecking often today. It's going to be a long 8 months.
