did you originally book these flights by calling Delta, or online?
I booked on-line at the Delta website. In the past they have called me when changes happened, but not this time. This disturbs me more today than it did last night. Not only was it possible for us to miss our first flight, but we would have been stranded in ATL on the return home. And then there is the issue with the first class not really being first class, even when the airplane has a first class section. Delta's computer charged me the big money, and then sat us in coach for 2 of the 4 flights (which is what it was yesterday when I first noticed it).
