I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

The flight was an hour and a half late departing which was inconvenient

The flight was great. The gate location was way to far away!!!

The flight attendant in first class was beyond rude and didn't care at all about her job. AND the gate agent was even worse than the flight attendant for rudeness. She was awful.

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Food was surprisingly good but the WiFi was not great

this crew didn't care much. bumping carts into seats more times than i care to remember

Everything was fine except the entertainment was not working for half of the flight.

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.

We didn't take off until an hour after we boarded.

Wish they had the seat-back video screens for watching movies or playing games.

Very good but wish they had the seat-back video screens for movies & games

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.

Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

This flight never occurred because AA couldn’t get their act together.
