I’m not delta, but I live in ATL and commute to DEN. Fairly painless with lots of direct mainline flights... latest usually go out around 10pm from ATL back to DEN. Plenty of options/airline variety.

Only issue I’ve had was when it gets hot here and flights get payload optimized.. agents bumped off 20 people and I got left behind a few weeks ago when it was 105 here. Afternoon storms love to pop up in Denver and screw with evening arrivals but I’ve only been based here during the hot months so not sure about commute issues in the winter.
