One of the worst flights ever. I got to the airport early for my 6:48 pm flight and tried to get on the 4:30 ish flight. The gate agent was one of the worst customer service people in my 20 yrs of flying Delta. Very rude and wouldn’t even talk to me about riding standby. Then flight took off 3 hrs late and when Landed in Atlanta, the gate people wouldn’t even try to get me on the plane. It was still there but door was closed. For all of my almost 2 million miles, the worst experience from Delta. I am highly disappointed as it was not my fault I have to sleep in Atlanta and not Jacksonville Florida
