I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Delayed. Hot. Passenger next to me was so large I couldn’t move.

2+hrs delay without any reason provided and a cramped flight

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

The crew, and fellow passengers, were super gracious and kind. There seemed to be plenty of bin space even though the plane was full. It’s nice to get a glass of wine with dinner in Premiere seating, and there was a lot of food.

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Originally, I was booked in economy. I paid several hundred additional dollars to upgrade to first class. Then I paid several more hundred dollars to change my flight to a slightly earlier flight. I asked if the changed flight would also seat me in first class, and I was told that it would. When I boarded the plane, however, I was seated in economy. So, I paid $500-600 more than I paid for my original ticket for an upgrade and a changed flight - received the changed flight (which was nice), but did not receive the upgrade. So, I was not completely satisfied.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.
