I felt bad calling when all the airlines are busy with Ian, but, after some unpleasant exchanges with a completely incompetent agent via chat I went ahead and plugged my phone in on speaker and listened to elevator music for 45 minutes while working until I got a live person with Delta. After the initial attempt of them trying to keep me on a redeye, and the person clearly understanding what my complaint was, she said yes she should could put me back on the afternoon flight to ATL that was only 13 minutes different than what I previously booked. She just had to go get override codes. 10 minutes later she was back on and fixed everything.

I can't think of any reason other than trying to get me on cheaper flights that they would try such a thing seems how the price has doubled since I booked in May. Complete scam IMO.
